by Isma Nazli Bashir | Prof. Dr.Zrafar Iqbal Ch | Dr.Peter J.Irwin | Prof. Dr. Azhar Maqbool | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 2008Dissertation note: An epidemiological study of babesiosis in dogs was conducted at Pet center, University of Veterinary and Animal Sciences, Lahore, for one year and information on age, sex and breed was gathered. It was found that from a total number of 6204, dogs up to two years of age were more susceptible than other age groups (2-4, 4-6 and above 6 years).The data regarding genders revealed that males were more prone to the disease than female dogs. As far as the breeds were concerned, crossbred dogs were more susceptible followed by Pointers, Alsatians, German shepherds and Bull terriors.Hot and humid months (June to September) have greater impact on the occurrence of disease. The study regarding identification of ticks revealed that Rhiphicephalus sanguinus is the predominant vector of the disease in Pakistan. Molecular studies were conducted to characterize and identify the species responsible for canine babesiosis in Pakistan. In this regard, a nested polymerase chain reaction-Restriction fragment length polymorphism (PCR-RFLP) technique was employed on different specimens (Blood, Body tissues and Ticks). For this purpose blood samples were collected from twenty four chronically infected dogs and applied on the Flinders Technologies Associates (FTA) cards for transportation to Australia. Different body tissues (Liver, Spleen, Kidney, Intestine, Bone marrow and Pancreas) were procured after euthanizing the two dogs and DNA was extracted, for further studies. Similarly, the eighty eight ticks were also collected from the infested dogs in the 70% ethanol for transportation to Australia. A nested PCR-RFLP assay was used for the detection and differentiation of Piroplasm species on the basis of the 1 8S ribosomal RNA gene. The assay potentially amplified and identified Babesia gibsoni as the main canine piroplasm. Similar assays on the DNA extracted from body tissues and ticks revealed Babesia gibsoni as the main piroplasm. The PCR was found to have a high detection limit (equivalent to i0 dilution), when using the DNA extracted from blood applied to FTA cards, body tissues and ticks. A new technique was developed for extraction of DNA from FTA cards and tick, in this technique, instead of using the FTA specified punching machine, we used scalpel blades, and so the rest of the chemicals used are'generally and easily available. The same protocol was used for extraction of DNA from ticks, only chemicals used in different quantities with different spinning times. Both of which, resulted in cost reduction, less effort and speedy DNA extraction. The technique reported here has the potential to be standardized for routine DNA extractions from FTA cards and ticks. Availability: Items available for loan: UVAS Library [Call number: 1061,T] (1).

Material type: book Book; Format: print Publisher: 2009Dissertation note: Field study was conducted from September, 2007 to August, 2008 and a total of 2700 rectal faecal samples were collected from cattle farms of 3 categories i.e. Government Dairy Farm, Military Dairy Farm and Peri Urban Dairy Farms (Gawala Colonies) Lahore. Seventy five random samples were collected from each category of farms on monthly basis. The results of field study showed that overall prevalence of coccidiosis in cattle was 54.55%. Prevalence of coccidiosis in cattle at Military Dairy Farm Lahore was the highest (65.33%) during Autumn followed by summer (52.66%) then winter (47.66%) whereas the lowest (34.00%) during spring season. The highest (56.66%) prevalence was observed in animals between 6 & 12 month, whereas the lowest (46.33%) in animals under 6 months age. Prevalence of coccidiosis above 1 year of age was 50.66%. No coccidial oocysts was detected in calves less than 15 days old. In female animals prevalence was 51.22%.In the present study, the maximum oocyst per gram of feces (OPG) count was 65,000 whereas the minimum count was as 2000. The count was variable in different age groups and found to be decreasing in adult animals. The mean OPG in group A (under 6 month), group B (6 month to one year) and C (above one year) was 44000, 38000, and 22000, respectively. The four species of Eimeria were identified in all age groups i.e. E.bovis (29.28%) E.zuernii (26.03%) E. cylindrica (23.42%), E. ellipsoidalis (21.25%). The results of field study showed that prevalence of coccidiosis at Government Dairy Farm, Lahore was the highest during autumn (49.33%), followed by summer (44.33%), then winter (38.33%) where as the lowest during spring (30.33%). The highest (62.66%) month wise prevalence of coccidiosis was noted during August whereas the lowest (28.00%) during April. The highest ( 45.33%) prevalence of coccidiosis was observed in animals aged between 6 to 12 months, followed by 41.35% in animals under 6 months of age whereas the lowest (36.00%) above I year. Female animals were more frequently affected (41.28%) than males (39.50%).In the present study, the maximum OPG count observed was 55,000 and the minimum count as 2500. The counts were variable in different age groups and found to be decreasing in adult animals. The mean OPG of group A, B, C was 42,000, 35,000 and 20,000 . In the present study five species of Eimeria were E.bovis. E. zuernii E. cylindrica, E. subspherica, E. ellipsoidalis. The results of field study showed that prevalence of coccidiosis at Peri Urban Dairy Farms (Gawala colonies), Lahore was 71.55%. Month wise prevalence was the highest during August (90.66%) whereas the lowest (48%) during April. The seasonal prevalence indicated that it was the highest during autumn (84.00%), followed by summer (78.33 %), then winter (69.33%) whereas the lowest during spring (50.00%). The highest prevalence of coccidiosis (80.66%) was observed in animals under 6 months of age, whereas the lowest (62.33%) in animals above I year. Prevalence of coccidiosis in animals aged between 6months to 1 year was 71.66%. No coccidial oocysts were detected in calves less than 25 days old. Prevalence of coccidiosis was higher (74.61%) in females than in males (63.60%). In this study, the maximum OPG count observed was 65,000 and the minimum count as 2800. The counts were variable in different age groups and found to be decreasing in adult animals. The mean OPG of group A, B,C was 48,000, 38,000 and 23,000 respectively. Age wise analysis of Eimeria species showed that above mentioned five species were found in all age groups and most predominant species was E.bovis (26.39%) followed by E. zuernii (19.87%), E. cylindrica (23.60%), E.ellipsoidalis (18.63%), whereas the lowest prevalence of E.subspherica (11.49%)was noted (Table 16). The counts were variable in different age groups and found to be decreasing in adult animals. There was inverse correlation of OPG and the age of animals. The overall prevalence of coccidiosis was the highest during autumn (66.22%) followed by summer (59.66 %) then winter (51.77%) whereas the lowest in spring (38.22). The role of Meteorological data i.e. temperature, humidity and rain fall on the prevalence of disease was also studied. The bionomical showed that humidity and rain fall played a very important role in the causation and spread of disease and also help in the development of sporulated oocyst. Increased temperature showed higher prevalence of disease. The results of histopatholgical studies showed that there was an increase cellular infiltration of leukocytes, cellular debris in most of intestinal portion. Results of therapeutic trials by using toltrazuril, amprolium, sulphaquinoxaline, lasalocid are presented in table 17. The result of therapeutic trials showed that efficacy of toltrazuril was better than amprolium, sulphaquinoxaline and lasalocid. No clinical signs of disease were observed in treated animals while in diseased animals signs of disease were observed i.e. animals showed diarrhoea, loss of weight gain. From the results it was noted that efficacy of toltrazuril was better than other drugs . Statistically, there was no significant difference between efficacies of all four drugs. The efficacy of per oxygen based disinfectant was higher as compare to oocide while non- treated animals showed clinical signs of disease. Statistically, there was no significant difference between efficacies of both disinfectants Result of chemo prophylactic products are presented in table 19. It was noted that sonicated vaccine showed high antibody titer as compare to non- sonicated vaccine. Result of the challenge experiments revealed that the inactivated sonicated vaccines gave 100% protection to the challenge calves. Their faeces were normal and no clinical sign was recorded even 42 days post vaccination. Few remaining live oocysts were not able to produce the disease in calves. The weight gain of treated animals was higher as compare to non-treated animals. The FCR value in treated animals was better than non treated animals " Prevalence of coccidiosis was the highest during autumn followed by summer where as the lowest during spring. Farm wise prevalence of coccidiosis indicated that it was higher in Peri Urban Dairy Farms followed by Military Dairy farm where as the lowest at Government Dairy farm. " Prevalence of coccidiosis was higher in calves below 9 months of age than above 9 months. All the animals examined for coccidian were naturally infected with coccidiosis. These animals were not experimental calves and prevelance of infection was based on random selection of animals. Overall Prevalence of coccidiosis was slightly higher in females than male. Species wise prevalence indicated that Eimeria bovis is more pathogenic than other species. " Results of chemotherapeutic trials showed that among the four drugs used i.e. Toltrazuril, Amprolium, Sulfaquinoxaline and Lasalocid. Toltrazuril showed the highest efficacy followed by Amprolium, where as Lasalocid showed the lowest efficacy. No side effects of these drugs were noted when were given at their recommended dose rate and marked clinical improvement in animals was noted after treatment. " Two disinfectants were tried. Per oxygen based disinfectant showed better results than. Oocide disinfectant. " Histopathological studies showed inflammatory granulocytic infiltration of the mucosa and cellular debris in most of intestinal portions. There were necrosis of villi and degeneration of villi. Haemorrhages in mucosa and sub-mucosa were noted. Some of the glands in the sub-mucosa of intestine showed degeneration & necrosis. " Indirect Haemagglutination (IHA) antibody titer was higher in calves vaccinated with inactivated sonicated vaccines as compared to the calves vaccinated with inactivated sporulated vaccine. Results of the challenge experiments revealed that the inactivated sonicated vaccines gave protection to the challenge calves. Their faeces were normal and no clinical sign of disease were observed even 42 days post vaccination. " Weight in infected group was reduced. After treatment, high weight gain was reported in treated animals than control group. Recommendations: " Overcrowding should be avoided. " Provide good hygienic and managemental conditions in farms. " Proper drainage of rain. " Feeders and wateres should be above the level of the ground. " Regular use of coccidiostats is the need of the day. " Diseased animals particularly with diarrhoea should be separated from healthy animals. " Stocking density should be according to recommended of world Association of Parsitologists. " Contaminated faeces should be properly disposed off. " Grazing of animals during rainy season should be avoided. " Animals should be provided well balanced nutritive food. " Entry of visitors in the livestock farms should be restricted Availability: Items available for loan: UVAS Library [Call number: 1281,T] (1).

by Muhammad Yasir | Prof. Dr. Kamran Ashraf | Dr. Aftab | Prof. Dr. Azhar Maqbool.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2011Dissertation note: Caecl coccidiosis is caused by Eimeria tenella and E. necatrix and poultry industry is facing huge economic losses due to this infection world wide. Eimeria tenella is the most common cause of caecal coccidiosis but E. necatrix is also isolated rarely. In the present study, 400 caecal samples suspected for coccidiosis were collected from two districts (Lahore and Gujranwala). Ten samples from twenty farms of each district were collected and examined for coccidiosis and species identication. Prevalence of coccidiosis was found 68%. It was more prevalent in district Gujranwala (71.5%) as compared to Lahore (64.5%). Eimeria species were identified by conventional (Direct Microscopy, Sedimentation technique, Floatation Technique and Sporulation) and molecular technique (PCR). Polymerase chain reaction was found the most sensitive ands accurate technique for species identification as compared to all conventional techniques. The prevalence percentage of E.tenella and E,necatrix was found 68% and 12.5% respectively. E.tenella was more prevalent in district Gujranwala (71.5%) as compared to district Lahore (64.5%). E.necatrix was also more prevalent in district Gujranwala (13.5%) than district Lahore (11.5%). The difference in percent prevalence of coccidiosis and species of Eimeria may be due to difference in farm management, farming type, biosecurity measures.

by Abdul Sajid | Prof. Dr. Zafar Iqbal Chaudhry | Dr. Aftab | Prof. Dr. Azhar Maqbool.

Material type: book Book; Format: print ; Nature of contents: biography; Literary form: Publisher: 2010Dissertation note: Goat pox is the most important pox diseases of livestock and it usually causes huge economic losses. The economic losses occur in terms of mortality, reduced productivity and lower quality of wool and leather. The clinical manifestations of the disease include high temperature, lesions skin in the form of macules, papules, vesicles, pustule and scabs on hairless areas of the body. The disease is highly contagious having high morbidity and mortality in the infected herds. The present study was conducted to document the prevalence of goat pox disease in the different regions of Punjab. The study was based on clinical manifestation of the disease in various collecting spots including slaughter houses, cattle and hide markets and tanneries. The prevalence of goat pox at slaughter houses in different regions was 9.93% in arid region followed by 8.69% and 7% in southern and northern irrigated regions respectively. The prevalence of pox disease in sheep was highest (8.54%) in the northern irrigated region, 7.69% and 6.62% in arid and southern irrigated regions respectively. The prevalence of pox recorded in the hide markets shows a trend of high presence 7.29% in arid region followed by 6.22% and 3.84% in southern and northern irrigated regions. Whereas in sheep the overall prevalence was 0.51 %, 4.44% and 1.66% in northern irrigated, arid and southern irrigated regions. In tanneries the pox lesions were identified on the basis of method as adopted in hide markets. The overall prevalence of pox in goat was 3.96%, 4.06% and 4.09% while in sheep 9.58%, 2.41 % and 10% in northern irrigated, arid and southern irrigated regions. The overall prevalence of pox disease in goat was 5%, 5.79% and 5.34% in Northern irrigated, arid and southern irrigated regions respectively. Where as in sheep, pox was 3.133%, 4.11 % and 2.67% in Northern irrigated, arid and southern irrigated regions respectively. The highest trend of incidence of disease was present in the arid regions followed by southern and northern regions. The slaughter houses shows high incidence of disease as compared to cattle and hide market and tanneries. The result was significant (P<0.05) among the regions and samples collecting spots. A total of 100 samples consisting of 55 scabs and 45 skin tissues were randomly selected from the different collecting spots of the three regions. The scabs and skin tissue samples were processed on dehydrated minimum essential media tor virus isolation. The virus was isolated on Vero cell line culture and its characteristics were observed on the basis of specific cytopathic effects. All 55 scab samples consisting 20 from cattle markets, 20 from slaughter house and 15 from hide market and tannery were tested through cell culture. The cell culture positive result for scabs was 60% cattle markets, 20% hide market and tannery and 40% slaughter house. All 45 skin tissue samples including 5 from cattle markets and tannery, 20 from hide market and 20 from slaughter house were subjected to virus isolation on Vero cell line. The cell culture positive result for skin tissue samples was 100% cattle markets, 30% hide market and tannery and 60% slaughter house. In this way the total cell culture result for scabs and skin tissue samples from all areas become 41.82% and 51.11 % respectively. The isolated virus was confirmed through peR. All the collected samples were also analyzed through peR in order to compare the two techniques for disease diagnosis. Out of 40 samples from slaughter houses 18 scabs and 15 tissues sample were positive through peR with 82.5%. Out of 25 samples collected from cattle markets consisting of 20 scabs and 5 skin tissues, 17 of scabs and 5 skin tissues were positive with 92%. Similarly a total of 35 samples out of which 15 were scabs and 20 were skin tissues collected from hide markets and tanneries. The peR of 7 scabs and 14 skin tissues was positive with 60%. In this way the total peR result for scabs and skin tissue from all areas was 42% and 34% respectively. In the 3rd study of the present project the isolated virus was inoculated in to experimental animal to study the detail pathogenesis. The disease followed the same pattern as in the natural outbreak. But however the routes of inoculation affect the severity of the disease. During the study the diseased animals were periodically slaughter at weekly interval after the appearance of 1 st clinical signs. The detailed lesions were observed in different visceral organs and the tissues were collected and preserved in 10% formalin. The tissues were processed for histopathology and immunohistochemical examination. The IHC was successfully optimized for the detection of viral antigen in the tissues of skin, lung and lymph nodes.

by Hafiz Javed Iqbal | Prof. Dr. Azhar Maqbool | Dr. Muhammad | Prof. Dr. Athar Khan.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2011Dissertation note: Hydatidosis is a world-wide zoonotic parasitic disease which is caused by the larval stage of tape worm Echinococcus granulosus and E. multilocularis. It is highly endemic in some regions of the world. Keeping in view the importance of the disease, the present study was conducted to record the age, sex, species and season wise prevalence of hydatidosis in small ruminants. The study also includes comparison of the two serological tests used for the diagnosis of this disease and efficacy of mebendazole was aIso evaluated. Prevalence and organ specificity of hydatidosis was studied in 2400 sheep and 2400 goats of different age and sexes. The overall prevalence of hydatidosis in sheep and goats was 8.25 and 6.21 percent respectively. Sex wise prevalence indicated that it was 9.85 and 7.85 percent in female and male sheep respectively whereas in female and male goats it was 5.83 and 7.23 percent respectively. A reasonably higher prevalence of hydatidosis was observed in female animals as compared with males. In adult animals hydatid cysts were present in 11.38 and 7.77 percent in sheep and goatsrespectively while in lambs and kids it was 1.79 and 1.06 percent respectively. Statistically no significant difference was observed in any season through out the year in both the species. In the present study, lungs were found to be most commonly infected organ in sheep andliver in goats. Out of 198 infected sheep, 45.45 percent had cysts in lungs, 33.84 percentin liver, 10.10 percent in both liver and lungs, 2.53 percent in spleen, 2.02 percent in heart and 6.06 percent in abdomen and thoracic cavity whereas in goats organs specificity was 34.23, 40.27, 16.78, 0.67, 8.05 percent respectively for lungs, liver, lungs & liver both, spleen and abdomen and thoracic cavity. A total of 60 cysts in sheep were examined for fertility and it was found that out of 18 cysts of less than two centimeter size, maximum (50 percent) were suppurative orcalcified and minimum (16.7 percent) were fertile in nature. Of 30 cysts of 2-4 em size, 40 percent were suppurative and 40 percent were fertile and from 12 cysts of more than four centimeter size, maximum (66.7 percent) were fertile and only 16.7 percent were sterile in nature. In goats, of 15 cysts of less than 2cm size, maximum (46. 7percent) were suppurative, and minimum (13.3 percent) were fertile. Of 7 cysts, belonging to the group of more than four centimeter seize, 71.4 percent were fertile in nature and only 14.3 percent were sterile. Overall fertility rate in sheep and goats was 38.33 and 36.96 percent respectively whereas overall sterility rate was 23.3 and 32.60 percent in sheep and goats respectively. In sheep, total number of protoscolices found in 23 cysts was 936 of which 72.65 percent were fertile in nature. The mean of total proto scolices was 40.70 with standard deviation of 23.05 whereas the mean number of viable protoscolices was 29.57 percent with a standard deviation of 18.92. In goats, total number of protoscolices observed in 17 cysts was 719 whereas only 52.71 percent were fertile in nature. The mean of total protoscolices was 42.30 with a standard deviation of 17.13 whereas mean of viable protoscolices was 22.30 with standard deviation of 17.10. Blood samples of 40 positive and 40 negative sheep for hydatid disease were collected from slaughter house and serum was separated. ELISA and IHA test were applied on these samples. The sensitivity, specificity, efficacy, positive predictive value and negative predictive value of ELISA were 92.5 percent each whereas these values for IHA were 80 percent, 97.5 percent, 88.75 percent, 96.96 percent and 82.98 percent respectively. In goats, blood samples from 40 positive and 40 negative cases of hydatidosis were collected from slaughter house before slaughtering and ELISA and IHA were applied on all of these samples. The sensitivity and specificity of ELISA was 90 percent and 95 percent respectively whereas the sensitivity and specificity of IHA was 75 percent and 97.5 percent respectively. A total of 12 i.e. 6 sheep and 6 goats (healthy) were purchased and kept at Ravi campus Pattoki, University of Veterinary and Animal Sciences, Lahore. These were divided into experimental (4 sheep and 4 goats) and control group (two sheep and two goats). In experimental group, 100 eggs of Echinococcus granulosus were given orally to all animals and then mebendazole was given to two sheep and two goats on zero day and then after two months intervals. Blood samples were collected from all animals on zero day, 90 days and 180th day and serum was separated. ELISA and IHA were applied to all samples. Mebendazole was not found completely effective and ELISA detected the infection earlier than IHA. On postmortem examination, multiple cysts were found in all animals of group A and no cyst was found in group B. Eighty blood samples of humans i.e. 40 positive and 40 negative for hydatidosis were coilected, serum was separated and ELISA and IHA test were applied to all the samples. The sensitivity and specificity of ELISA was 95 percent and 97.5 percent respectively whereas the sensitivity and specificity of IHA was 82.5 percent and 97.5 percent respectively. The present study will be helpful in disseminating the informations regarding the prevalence, zoonotic importance, effect of mebendazole in animals and the use of immunodiagnostic tests for the diagnosis of hydatidosis in small ruminants and human beings.

by Zakir Ali | Prof. Dr. Azhar Maqbool | Prof. Dr | Prof.Dr. Khushi Muhammad.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2010Dissertation note: A study to investigate prevalence of different genera of hard ticks was carried out in three districts of the Punjab province, Pakistan (Faisalabad, Jhang and Khanewal). Overall prevalence of Hyalomma species is the highest at 61 % as compared to other genera of hard ticks. In sex-wise distribution, it was found that female Hyalomma species were the highest at 85% followed by A mblyomma species at 81 %, whi Ie Rhipicephalus (Boophilus) species and Haemaphysalis species were at 77%. Infestation rate in cattle at 70% was higher as compared to buffaloes at 34%. In tick infestation level study, high infestation level in cattle at 59% was higher as compared to that of buffalo population at 18%. In cattle population, peR results showed the prevalence of T annulata in H anatolicum and Hidromedari ticks as 50% and 40% respectively. No theilerial organism was detected in Himarginatum, Rhipicephalus (Boophilus) annulatus and Amblyomma variegatum ticks. Three different types of vaccines were prepared from different organs of ticks i.e., salivary gland, intestine or whole ticks of the same species of Hyalomma and they were injected to rabbits. It was found that vaccine prepared by grinding whole tick produced the higher level of antibody as compared to two other vaccines. Each of the whole tick homogenate vaccine prepared from either of the species of Hyalomma, Rhipicephalus or Amblyomma and injected to rabbits. These vaccines produced antibody as well and cross reacted with each other showing each of the hard ticks were antigenically similar. Efforts were made to prepare oil based whole Hyalomma tick vaccine with three different antigen concentration 5.0 mg, 7.5mg and 10.0 mg and evaluated its potency in buffalo calves. It was found that the vaccine dose containing 5.0 mg antigen per dose did not produced detectable antibody in buffalo calves while the vaccine containing 7.5mg or more antigen produced detectable antibody. Moreover, we concluded that montanide based bard tick homogenate vaccine with more than 7.5mg protein per dose is effective in producing antibodies against tick infestation in the dairy animals. The antibody level in vaccinated buffaloes as well as invaccinated rabbits reached to peak level on day 45 post vaccination and started declining thereafter. Capacity of vaccine in controlling tick infestation was assessed in 12 cross-bred calves. It was found tbat rejection percentage in immunized group was higher as compared to control group. There was no difference of engorgement period between immunized and control group. Reproductive index in immunized group was lower as compared to control group. The efforts were made to grow midgut cells insect culture media after isolation them from Hyalomma Ticks.. The purpose of this experiment was to grow midgut cell and then use these cells as a source of was found that the vaccine dose containing 5.0 mg antigen per dose did not produced detectable antibody in buffalo calves while the vaccine containing 7.5mg or more antigen produced detectable antibody. Moreover, we concluded that montanide based bard tick homogenate vaccine with more than 7.5mg protein per dose is effective in producing antibodies against tick infestation in the dairy animals. The antibody level in vaccinated buffaloes as well as in vaccinated rabbits reached to peak level on day 45 post vaccination and started declining thereafter. Capacity of vaccine in controlling tick infestation was assessed in 12 cross-bred calves. It was found tbat rejection percentage in immunized group was higher as compared to control group. There was no difference of engorgement period between immunized and control group. Reproductive index in immunized group was lower as compared to control group. The efforts were made to grow midgut cells insect culture media after isolation them from Hyalomma Ticks.. The purpose of this experiment was to grow midgut cell and then use these cells as a source of contamination for the tick cell culture which are extrinsic as well extrinsic. The growth rate of these cells in our study was not optimal so the media was not splitted to get more cells. Availability: Items available for loan: UVAS Library [Call number: 1416,T] (1).

7. Prasitic Contamination Of Vegetables Eaten Raw In Lahore

by Shafa-ul-Haq | Prof. Dr. Azhar Maqbool | Dr. Muhammad | Dr. Nisar Ahmad.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2012Dissertation note: Fresh vegetables are important part of human diet. Eating raw vegetable is customary in many parts of the world including Pakistan, but these raw vegetables can be a major source of parasites. A parasitic survey on vegetables collected from major markets in Lahore was conducted for the discovery of human and animal parasites. Ten species of vegetables: beet (Beta vulgaris), cabbage (Brassica denceal), carrot (Davcus carota) chili (Capsicum frutecense), coriander (Corriandum sativum) cucumber (Cucumis sativa), lettuce (Lactuca sativa), Mint (Mentha viridis), radish (Raphanus sativus), tomato (Lycopersicon esculentun) were evaluated in this study. Fifty samples of each vegetable were taken, comprising a total of 500 samples for the study. Hundred gram of each vegetable was washed with a cationic solution of Hyamin detergent containing glass particles for the elution of eggs. Concentration of eggs/cysts was achieved by centrifugal sedimentation technique at 5000 rpm for 5 minutes. Sediment was examined under microscope for the presence of parasite eggs, cysts and larvae. Examination of vegetables revealed twelve genera of parasites. All vegetables were highly contaminated with parasites with an overall prevalence of 31.2%. Of parasites studied, Ascaris eggs found to be the highest (37.1%), followed by Hook worm(10.8%) and Trichostrongyloides sp.(8.9%), while the least common parasite was Toxoplasma gondii (1.9%). Lettuce showed the highest contamination (48%), followed by Cabbage (44%) and Mint (podina) (42%) while chili showed the least contamination (16%). The results would seem to indicate that one of the important routes of parasitic infection is due to consumption of raw and unwashed vegetables. So, enlightenment programs for the public on necessity of food sanitation and personal hygiene should be intensified. Availability: Items available for loan: UVAS Library [Call number: 1419,T] (1).

by Asemah Anwar | Prof. Dr. Azhar Maqbool | Dr. Aneela | Dr. Nisar Ahmad.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2012Dissertation note: Pakistan is one of sub-tropical countries and its climatic conditions favor parasitic diseases along with disease vectors including mosquitoes. Mosquitoes of genus Aedes are causing Dengue fever. It has become one of infectious vector born disease of world. Annually it is striking around 100 million people with dengue fever and about 5 Lac people with Dengue Hemorrhagic Fever (DHF), resulting in 5 % deaths per year. Current study was conducted to evaluate efficacies of plant extracts against dengue fever mosquitoes of Aedes genus. Study target was to search some safer alternates than that of chemical pesticides. Also exhibiting characteristics like less toxic to environment, do not induce resistance in mosquitoes, do not harm non-targeted organisms, would not be toxic to human beings and will have biodegradation ability. Study has evaluated indigenous plants extracts as potent larvicidal and adulticidal materials. Mosquitoes were collected from different areas of Lahore and they were identified upto genus level only Aedes genus was identified upto species level, then Aedes aegypti was reared in laboratory to have F 1 generation, to have mosquitoes and larvae for testing the activity of plant extracts. Plant materials were collected from different areas of Lahore. Methanolic extracts of seeds and leaves of Azadirachta indica and lantana camara respectively, were extracted accordingly. Stock solutions were prepared from these extracts and then out of this serial dilutions were made. Experiment was performed in four groups A, B, C & D for both adults and larvae. Each group was representing total of 25 larvae/adult out of which one was kept untreated as negative control, one with deltamethrin as positive control while two were provided with test concentrations. LC50 and LC90 was determined by Probit analysis, using SPSS version 13.0 SPSS inc. 2004. lethal concentrations of A. indica mosquitocidal assay were LC50=30.44 mg/l and LC90=62.36 mg/l after 24 hrs and LC50=-9.87mg/l and LC90=59.102 mg/l after 48 hrs at ?= 0.05. X 2 value was significant for 24 h while for 48 h it was not significant. Maximum mortality observed after 24 and 48 hrs is 99% at 70 ppm. DMR test shows after 24 hrs., all treatment means are significantlt different from each other, from control and from mean of insecticide's mortality, control is significantly lower while insecticide treated group has significantly higher than rest. after 48 hrs. treatments were significantly different from each other while treatment mortality at 70 PPM is significantly higher than insecticide treated group and rest. Lethal concentrations for L. camara adulticidal assay were LC50=60.40 mg/l and LC90=113.61 mg/l after 24 hrs and LC50=48.20 mg/l and LC90=79.31 mg/l after 48 hrs at ?= 0.05. X 2 value was not significant at 24 h and is significant at 48 h. DMR test after 24 hrs. treatment, control and insecticide treated were significantly different from each while insecticide treated group has significantly higher than rest. After 48 hrs 4 and 5 treatment groups were found significantly higher than rest Larvicidal assay of A. indica has shown LC50 =52.36 mg/ l and LC90=105.42 mg/ l after 24 h and LC50 =80.70 mg/l and LC90=145.73 mg/ l after 48 h at ?= 0.05. X2 values for both 24h and 48h were not significant. DMR test after 24 hrs. insecticide treated was significantly lower than all above treatment groups. Treatment group 7 has significantly higher mortality than all other. After 48 hrs. there was not any significant difference. Lethal concentrations for L. camara LC50 =100.76 mg/100 ml and LC90=198.22 mg/100 ml at24 h and LC50 =61.27 mg/100 ml and LC90= 122.45mg/100 ml after 48 h at ?= 0.05. X2 value for both 24h and 48h was not significant. DMR test after 24 hrs. shows insecticide treated group i.e. 8 is significantly lower than all treatment groups except 1 which is at lowest treatment. After 48 4, 5 and 6 had came to same activity level no significant difference was found and were higher than all others. Conclusion: Hence it is concluded that crude plant extracts can act as potential Adulticide / Mosquitocide and Larvicides, though these are required in higher concentrations than that of synthetic insecticides and purified botanical products, but they have advantage of posssessing less resistance presentation and safe for aquatic life. It is also concluded that chemical insecticide used i.e. Deltamethrin has higher efficacy as adulticidal with drastic effects on environment and other beneficial insects. But it was found least effective as larvicidal compared to crude plants extracts. It is suggested that plant extracts can prove a better, safer and cheaper alternate these should consider as a better alternate to control most lethal disease of present time i.e. Dengue fever by eradicating its vector i.e. Aedes aegypti mosquito.

by Imtiaz Aziz | Prof. Dr. Azhar Maqbool | Prof. Dr | Prof. Dr. Kamran Ashraf.

Material type: book Book; Format: print Publisher: 2012Dissertation note: Due to intensification of fish culture practices, there is more likely the occurrence of various diseases in general and parasitic in specific in fish. However, there is a paucity of information regarding the prevalence of various parasites in local fish especially fishes of fresh water. Therefore, the present study has been planned to investigate the prevalence of various parasites of the gastrointestinal tract and liver of Wallago attu(Malee) ,Rita rita (Khaga), Channa marulius(Saul) and Mystus seenghala(Seenghari). Therefore, it was hypothesized that there is a variation in the occurrence of various endoparasites in various species of fish. A total fifty gut samples from each of breed of fish (Wallago attu (Malee),Rita rita (Khaga), Channa marulius(Saul) and Mystus seenghala(Seenghari) were collected from various fish markets located in Lahore City like Bhatti Gate, Samnabad, Tollinton Market, and were analyzed to determine the prevalence of various endoparasites in the intestine. The gut samples were collected in 0.9% physiological saline and were preserved in 4% formalin. The recovered parasites were fixed and identified on the basis of morphology to calculate the prevalence rate. The data thus collected was analyzed using a Pearson's chi-square. Results showed that out of 65 fish samples collected from Tollinton market that included Rita rita (n = 20), Wallago attu (n = 15), Channa marulius (n = 15) and Mystus seenghala (n = 15), 7 (10.76%) samples of gut harbored various parasites. Similarly, the prevalence rate of parasites in two other localities were 17.39% in Bhatti-gate fish market and 18.18% in Samanabad Fish market. The overall prevalence rate was found to be 15.5%. There was no statistical difference in the prevalence rate when data was assorted on the basis of localities. Both single and mixed infections were noted in fishes collected from all three localities and all four species of fresh water fish. The various parasites revocered from the intestines of the gut from all species included P. heteropneustus Cucullanus sp., Cucullanus sp., Phyllodistomum sp. and R. magna.

12. Epidemiological And Molecular Profile Of Hepatitis-C Viral Infection Among Different Groups Of Population In And Around Lahore, Pakistan

by Dr. Abdul Majeed Akhter | Prof. Dr. Muhammad Athar Khan | Prof. Dr. Azhar Maqbool.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2012Dissertation note: Hepatitis C is an infectious disease affecting primarily the liver, caused by the hepatitis C virus (HCV). The infection is often asymptomatic, but chronic infection can lead to scarring of the liver and ultimately to cirrhosis, which is generally apparent after many years. In some cases, those with cirrhosis will go on to develop liver failure, liver cancer or life-threatening esophageal and gastric varices. The present project was carried out to study the prevalence of laboratory based confirmed patients of Hepatitis-C in various public, private hospitals and in high risk groups among the population of Lahore metropolitan and its distribution and pattern with respect to person, time and place. Second part of the project was designed to study the risk factors of Hepatitis-C patients from out patient departments of various public and private hospitals of Lahore. Individuals at high risk from different organizations and occupations across the city population of Lahore metropolitan were also included in the study. The third part of the project was designed to investigate the distribution of genotypes of Hepatitis-C virus among patients through RT-PCR and theireffect on viral load, various haematological and biochemical parameters. Project-I Study-1: To estimate the prevalence of hepatitis C in various public and private hospitals of Lahore Metropolitan among different groups a total of 1399 individuals were tested to estimate the hospital based prevalence of HCV. Out of these 233 individuals produced positive result for Hepatitis-C virus infection. The overall hospital based prevalence was estimated to be 16.66% during the year 2009. The current study revealed that the highest prevalence was estimated in Dialysis patients and Organ recipients (41.17%) followed by General Patients of age > 12 years (14.60%) and pregnant women (10.84%). It was further observed that the least affected group was the Children of age ? 12 years (3.85%). Study-2: The results of estimated prevalence of Hepatitis C virus infection in high risk groups from the population in and around Lahore revealed that the highest prevalence was estimated in patients with HIV/AIDS (36.36%) followed by injecting drug users (36.09%), blood donors (17.78%), long rout truck drivers (14.70%), house hold and direct contact personal (14.6%) and prisoners (14.28%). It was also find out that the less affected groups were police department (10.66%), staff nurses and other health care workers (9.87%) and barbers and beauticians (6.97%) while doctors and dental surgeons were least affected (1.32%) among the high risk groups. Study-3: To find out the pattern and distribution of HCV patients with respect to person place and time a total of 924 patients were selected from the registry of Provincial Hepatitis Control Cell Lahore through systematic random sampling. Out of these, 154 fulfilled the inclusion criteria. Among these, 90 were male and 64 were females. Average age of male and female patients was 35.88±10.49 and 37.78±9.12 years, respectively. The age difference between male and female patients was statistically non-significant (P-value>0.05). It was further observed that 147 patients were Punjabi and 7 were from other provinces. Moreover, It was found that the highest number of patients was observed during the month of December (n=18) followed by November, 2008 (n=15), March (n=15) and July, 2009 (n=14) while the least number of patients were observed during the months of September, 2008 and May, 2009 (n=10). Project-II To study the risk factors associated with HCV infection an analytical cross sectional study was conducted. Study-1: Lower socio economic class, place of birth (hospital), delivery assisted by whom and breast feeding were significantly associated with HCV infection in children of age ? 12 years. The mean age of reactive and non-reactive general patients was significantly associated (P=0.012) with anti-HCV status. Marital status (OR=2.042), socioeconomic status, blood donation (OR=2.15), prescription by doctor or non-doctor (OR=2.664), route of drug administration, relative having hepatitis and towel sharing (OR=1.987) were also significantly associated (P<0.05) risk factors for HCV infection. The mean age of reactive and non-reactive pregnant women was 27.55±3.43 and 25.37±4.24 years, respectively. Educational level (OR=3.093) and occupational status (OR=2.228) were the important risk factors associated with HCV infection. Tattoo on the body (OR=11.833), comb sharing (OR=20.86) and razor sharing (OR=4.786) were significantly associated (P<0.05) with HCV infection. Pregnant women who gave the history of dental procedures and tooth brush sharing were 3.15 and 4.12 times more prone to get HCV infection, respectively. In 205 patients having dialysis and organ recipients 41.17% patients were reactive for Anti-HCV. Blood transfusion, glass sharing and qualification of the patients were significant factors in this group. Study-2: In case of doctors/dental surgeons a significant association was observed with history of blood transfusion and duties in medical and surgical wards. The nurses who worked in surgical wards, visited beauty salons were significantly associated (P<0.05) with HCV infection. Among health care workers age, gender and other factors did not have any significant influence on the reaction of HCV. Among blood donors female to male ratio was 1:16.5. It was found that the occupational status (p=0.002), place of surgical treatment (p=0.035), history of blood transfusion (p=0.000), ever pricked by sharps (p=0.045), habit of injecting drugs (p=0.04) and glass sharing (p=0.017) were significantly associated with occurrence of hepatitis C in blood donors. In long route truck drivers geographical status, surgical procedure, dental treatment and family history were significantly associated (P<0.05). Among the injecting drug users, demographic factors like marital (P=0.007) and educational status (P=0.000) were found to be significantly associated with HCV infection. Furthermore, the behavioral factors; use of injectable drugs with reused syringes (P=0.003), sharing of syringes in groups (P=0.004), place of shaving (P=0.000), use of disinfected ustra (razor) (P=0.003) and razor sharing (P=0.000) were significantly associated with anti-HCV status for IDUs. Among HIV/Aids patients a statistically significant (P<0.05) difference was present among the ages of reactive and non reactive patients. Comb sharing has also a positive effect of HCV but all other factors were not contributing in this group. In Police personals odds ratio for married persons was higher (9.57) but statistically insignificant. The mean age for reactive persons was 39.75±8.24 years. A non-sexual contact with HCV patient and spoon sharing were significantly associated. In prison inmates skin infection and sexual involvement were significantly associated (P<0.000) with HCV infection. In the group of 43 barbers/beauticians age, working shift, tattoo on body (OR=19.5), injecting drugs (OR=19.5) and pre-testing for HCV (OR=19.5) were significantly associated with HCV infection. In house hold and direct contact group previous history of accidents and family history of HCV (OR=18.36) were significantly associated with HCV infection. Project-III A molecular epidemiological study was conducted in which the HCV reactive patients as tested by ELISA test were subjected to viral load and genotyping through RT-PCR. The positive cases of Project-I were included in this project. In the present study 558 patients were reactive for Anti-HCV. Out of these, 34 (6.09%) patients had Type-1 genotype, 67 (12%) patients were accounted for Type-2 and 410 (73.47%) patients were positive for Type-3. Multiple genotypes were seen in 19 (3.4%) patients, 9 (1.61%) patients had un-type able genotype whereas in 19 (3.4%) patients genotype could not be detected. According to the distribution of genotype-1, 1a was present in 30 (88.23%) while 1b was seen in 4 (11.76%) patients. In patients of Type-2 genotype, 2a and 2b were present in 54 (80.59%) and 13 (19.40%) patients, respectively. In patients having Type-3, 3a and 3b were identified in 353 (86.09%) and 57 (13.90%) patients, respectively. Furthermore, Bilirubin, ALT, AST, ALPT, viral load, Hb, TLC, DLC, Platelet and ESR were statistically same in all genotype.

14. Serofpidemiology, Zoonotic Potential And Chemotherapy Of Neosporosis In Dogs And Cattle

by Muhammad Mudasser Nazir | Prof. Dr. Azhar Maqbool | Dr. Muhammad Lateef | Prof. Dr.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2010Dissertation note: The aim of current study was to demonstrate the most important features of Neospora caninum infection in Pakistan. In the present study, I examined the prevalence of N. caninum in 7 districts of the country and to accessed the efficacy of various drugs against the parasite in cell culture. For the achievement of this purpose, the core objectives were, To have an overview on the overall seroprevalence of neosporosis throughout the country by means of cELISA in aborting, at risk and clinically healthy cows. To check the correlation of Iscom ELISA and cELISA, and determination of prevalence of N. caninum by means of Iscom ELISA on milk samples. To identify the transmission of disease towards human. To determine the efficacy of various drugs against N. caninum. In phase 1, overall seroprevalence of N. caninum in dairy cattle (detected by means of cELISA, VMRD, Inc., Pullman, WA, USA) was found to be 43.4% with a significant difference (P < 0.05) of seropositivity among all 18 herds (n = 5 aborting herds, n = 13 non-aborting/clinically healthy herds) selected from 7 districts of Pakistan. The seropositivity of cattle to N. caninum antibodies was significantly higher in aborting animals (52.7%) as compared to non-aborting cows ( 41.5%), indicating a significant difference between aborting and non-aborting cattle. In case of pregnant and non-pregnant animals, similar findings were recorded in our study. A significantly higher rate of seroprevalence was observed in pregnant dams (59.8%) than non-pregnant cattle (35.2%). Overall, higher serological prevalence was evaluated during the summer season (61.1%) in all areas followed by autumn (46.9%), spring (34.9%) and least seropositivity was observed in winter season (26.6%). The difference in seropositivity was significantly different among all age groups, greater in animals older than 2 years of age. Furthermore, the prevalence was statistically significant (P < 0.05) among cattle of different breeds. Seroprevalence in cases of crossbred animals were higher followed by exotic and indigenous breeds. Phase 2, describes the seroprevalence of N. caninum in clinically healthy dairy cows. A selection of 760 animals from 13 dairy herds located in Punjab and Sindh Province, Pakistan to demonstrate the presence or absence of the Neospora caninum infection in commercial dairy cattle. The serostatus of the cows towards N. caninum was detected by cELISA (VMRD, Pullman, WA). Out of 760 animals, (43.2%) were seropositive to N. caninum. A significant difference of positivity was recorded among all 13 dairy herds. Age wise prevalence though not statistically significant among all age groups, was greater in animals over 2 years of age and least in heifers. Variation was also observed in samples from cattle of different breeds. A significantly higher prevalence was observed in crossbred animals than in purebred and nondescript cattle. Seasonal prevalence was higher during summer season than rest of the seasons. The seroprevalence of N. caninum in pregnant cows was significantly greater than in non-pregnant animals. Second experiment of this phase describes the seroprevalence of 240 animals from 5 herds with a high rate of abortion, the percentage of seropositivity observed in these herds was 43.8%, slightly higher than the clinically healthy and non-aborting cattle. No significant difference was observed among all sample locations in this experiment. However, significant difference of positivity was recorded among different breeds of cattle. Age wise prevalence, though not statistically significant (P > 0.05), was greater in animals older than 2 years of age. The assessment of milk samples from lactating cows were also determined for Neospora caninum antibodies by means of Iscom ELISA (SANOVIR® Sanova Biotech AB, Uppasala, Sweden) and showed a good level of agreement (r² = 0.9959) between the two tests (cELISA and Iscom ELISA). Although, the cELISA (VMRD, Inc., Pullman, USA) expressed a higher seropositivity and sensitivity than Iscom ELISA (Sanova Biotech AB, Uppasala, Sweden). Therefore, both of the ELISA tests (cELISA and Iscom ELISA) for the detection of N. caninum antibodies in dairy cattle can perform better in lactating animals. The Iscom ELISA has some advantages over cELISA as it's easy to collect milk samples than serum samples, moreover Iscom ELISA is cheaper and easy to use but has low sensitivity than cELISA and cannot be used in dry animals. The percentage of positivity detected through Iscom ELISA on individual milk samples were 61.4% and 76.6% by cELISA. In phase 3, an epidemiological study was conducted to determine seroprevalence of N. caninum in dogs of different breeds and age groups. The serum samples of dogs were analyzed by cELISA (VMRD, Pullman, USA) showed a seropositivity of 23.5%. There was no significant difference of seropositivity among various sample locations, highest prevalence was observed in Muzaffar Garh (31.9%), followed by Gujranwala (27.9%), Lahore (25.1%), Hafizabad (20.2%) and least prevalence was recorded in district Okara (14.6%). A significant difference in prevalence of N. caninum antibodies between male (26.1%) and female (18.8%) dogs were recorded. The difference in seroprevalence was not significant among all age groups. The samples with no age record showed a highest prevalence (29.5%) and least seropositivity was observed in adult dogs of 3-6 years of age (18.7%). During Summer season, highest positivity to N. caninum was (31.0%) recorded while the lowest prevalence (16.0%) was observed in Winter season. Phase 4, describes the seroprevalence and transmission of N. caninum in humans. A selection of 52 serum samples from humans was analyzed for the presence of N. caninum antibodies. The serostatus of the humans towards N. caninum antibodies (IgG) was determined by using commercially available antigen coated IFAT slides (VMRD, Inc., Pullman, Washington USA) and human conjugate. Overall very low prevalence (1.9%) of N. caninum antibodies was reported in this study. Only one case was found to be positive, these findings indicate that no strong evidence of N. caninum infection in humans. In phase 5, in vitro drug trials was conducted to access the best efficacy of three commercially available drugs. We found that among three anticoccidial drugs i.e Clindamycin, Diclazuril and Sulfadiazine, Diclazuril has best inhibitory effect against N. caninum tachyzoites in cell culture followed by Clindamycin and sulfadiazine.

by Masood Ul Haq Kakar | Prof. Dr. Azhar Maqbool | Dr. Muhammad | Prof. Dr. Yasmeen Nawaz.

Material type: book Book; Format: print ; Nature of contents: biography; Literary form: Publisher: 2012Dissertation note: Various epidemiological aspects of human and sheep fasciolosis were investigated in four districts of Balochistan (Pakistan) having different ecology i.e. district Bolan from (Plain zone), Lasbela (Coastal zone), Qilla Saifullah (sub humid and semi arid sub zone of Upland zone) and district Pishin from (Arid sub zone of Upland zone). Sheep samples were examined through Coprological examination showed overall prevalence of 10.26% in one year study period from June 2010 t0 May 2011. The uppermost prevalence was recorded in district Bolan (14.79%) followed by Lasbela (10.63%), Qilla Saifullah (8.75%), and the lowest in district Pishin (6.88%). Overall the highest prevalence by season was recorded in autumn (25.31%) followed by winter (9.22%), summer (6.41%) and lowest in spring (5%). Amongst the month the overall highest prevalence was recorded in the month of September (30.63%) and lowest in the month of May (1.88%). Sex wise prevalence was found highest in female more susceptible to infection (11.22%) than male (8.48), but sex wise difference was non-significant statistically. Amongst the age group significantly higher prevalence was recorded in adults young than adult of age group (5.91%). During one year study period prevalence (%) of human fasciolosis in some districts of Balochistan was recorded (0.42%), with overall district wise prevalence in Qilla Saifullah and Bolan (0.83%) and (0%) in Lasbela and Pishin. Overall season wise prevalence was noted the highest in autumn (1.25%) followed by summer (0.63%) and 0% prevalence in winter and spring. Month wise results showed 2.5% prevalence only in the month of August and October while 0% in the other months. Gender wise prevalence 0.42% was found only in male, no female samples were collected due to some religious, traditional and community problems. Prevalence by age was recorded the highest in above 20 years of age group (0.74%) while this value decreased to zero in below 20 years of age group. Antibodies against fasciolosis in serum samples through indirect (ELISA) were recorded 13.13% (63/480) in sheep and 0.42% (2/480) in human indicates the higher prevalence (%) as compared to fecal examination. Likewise district, age and sex wise seroprevalence (%) of fasciolosis was reported higher than coprological examination in case of humans as well as in sheep. In sheep positive correlation was noted between fasciolosis and relative humidity while negative correlation with temperature (ºC) and rainfall (mm). While in humans prevalence positive correlation was observed with temperature (ºC), relative humidity (%) and rainfall (mm). Overall 1123 snails belonging to different 5 genera were collected from different district from different agr-ecological zones of Balochistan from June 2010 to May 2011. Amongst the snails the highest prevalence (37.04%) was found for Indoplanorbis, followed by Bulinus (32.15%), then Lymnea (20.66%), Melanoides (5.52%) and the lowest Physa (4.63%). Comparative study for coprological and serological tests (ELISA) was conducted for four districts from different agro-ecological zones of Balochistan i.e. District Bolan from (Plain zone), Lasbela (Coastal zone), Qilla Saifullah (sub humid and semi arid sub zone of Upland zone) and district Pishin from (Arid sub zone of Upland zone) for one year i.e. from June 2010 t0 May 2011. Overall prevalence of sheep and humans was 0% and 8.13% by coprological examination and 13.13% and 0.42% by indirect ELISA tests. Prevalence by ELISA was found higher than fecal examination when analyzed statistically. Similar seroprevalence for month, districts, age and sex was noted higher than coprological examination for sheep and humans. ELISA Sensitivity (%) and specificity (%) was recorded >97.0% and 95% and 100%, 100%, respectively for sheep and humans. Indigenous plants i.e., Saussurea lappa (roots), Fumaria parviflora (aerial) and Caesalpinia crista (seeds) were used at dose level of 60, 70 and 80 mg/kg body weight against naturally infected sheep with fasciolosis and their effectiveness was compared with triclabendazole (10mg/kg body weight). Triclabendazole was found 100 % effective after second dose whereas all herbal medicine it reached up to this mark after administration of second dose of 80 mg/kg body weight. From this study we can conclude that these herbal medicines can safely replace the triclabendazole, which is not, only cost effective but have no side effects.

by Bushra Nazeer | Dr. Nisar Ahmad | Prof. Dr. Anjum | Prof. Dr. Azhar Maqbool.

Material type: book Book; Format: print Publisher: 2013Dissertation note: The study was designed to check the prevalence of nematodes in pheasants. A total of 200 faecal samples (100 from Lahore Zoo & 100 from Jallo Park Lahore) were collected from pheasants. Faeces were examined by using direct smear and centrifuge floatation technique. Forty six out of 200 Pheasants were found to be infected with nematodes. The overall prevalence of nematodes was 23%, while 20% & 26% prevalence was reported for Lahore Zoo & Jallo Park Lahore respectively. The overall species wise prevalence of nematodes reported as, Capillaria, Ascaridia, Coccidia, Trichostrongylus and Heterakis 23.9%, 30.4% 19.6%, 2.2% and 23.95 respectively. Then forty five birds were selected for chemotherapeutic trial by using fenbendazole and tetramisole and checked the efficacy of these drugs against the nematodes. The decrease in mean of EPG in faecal samples was calculated before and after treatment. All the Pheasants in group A were treated with tetramisole and mean EPG was 1000 at day 0 (before treatment). The reduction in mean EPG after treatment was observed 293, 220 and 367 on days 3, 7 and 18 respectively and tetramisole efficacy was 71%, 78% and 63%. The lowest (63%) tetramisole efficacy was calculated after 7 day, likewise highest (78%) on day 7 after treatment. The overall percentage efficacy of tetramisole was calculated 71% during this drug trial. On the other hand in group B the mean EPG was 961 before treatment (on day 0). The mean EPG was calculated 226, 193 and 327 on days 3, 7 and 21 respectively after fenbendazole treatment, indicating the egg load reduction 76%, 80% and 65% respectively. In group B, the highest reduction load (80%) of eggs was calculated on day 7 after medication, on contrary 65% on day 18 (post-treatment). The significant difference (p<0.05) was seen in EPG before and after treatment with anthelmintic in group A and B. The efficacy of fenbendazole was found highly significant (p<0.02) than tetramisole.

by Abdul Razzaq | Prof. Dr. Kamran Ahraf | Prof. Dr | Prof. Dr. Azhar Maqbool.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2012Dissertation note: The main area of research in this study was to assess the prevalence, hematological and serological aspects of ovine nematodiasis. Four main experiments were conducted to highlight the objectives of the present research study. First experiment was conducted to find out the prevalence of sheep major nematodes for one year (January-December 2011). For this purpose three sheep breeds i.e., Balochi, Babrik and Harnai (either sex and between 1-5 years age groups)were selected randomly from three sites i.e., Quetta, Ziarat and Loralai. Faecal analyses of these sheep showed overall higher (40.25%) nematodes prevalence at Loralai followed by Ziarat (29%) and Quetta (23.92%). Five nematodes infection were recorded at three experimental sites. Among these, H. contortus (5.58 to 10.42%)and was the higher prevalent followed by N. battus (6.92 to 9.33%), S. papillosus (4.42 to 9%), T. colubriformis (2.33 to 7.33%) and T. ovis (1.83 to 6.83%).The nematodes prevalence was higher in one and five years old sheep. The female-sheep were infected with higher nematode prevalence higher the than male once and sometimes non-significant difference. These five nematodes were prevalent almost throughout the year; however, a peak infection was recorded during August/September. The high temperature, rainfall and humidity during these months may be predisposing factor of higher prevalence. Second experiment was on diagnosis of sheep nematodiasis through Enzyme-linked immunosorbent assay (ELISA). For this purpose H. contortus and T. ovis positive samples (200) based on coprological examination were also indicated 100% positive sensitivity by the ELISA based on crude somatic antigen, while on excretory antigen based showed lower (92%) sensitivity. The sera (n=200) of non-infected sheep (based on coprological examination) showed marked difference results. Such as 168 (84%) and 166 (83%) samples were found positive with H. contortus and T. ovis, respectively. While, based on crude somatic antigen 158 (79%) and 144 (72%) samples were found positive with H. contortus and T. ovis, respectively. Third experiment was conducted to determine the hematological values and total serum protein indices in healthy and nematodes infected sheep. The statistically significant (P<0.05) difference in PCV, Hb, RBC, WBC, Eosinophil, ESR and Total serum protein values was observed among healthy and nematode infected sheep groups. While, there was no statistically significant (P<0.05) difference in TLC, Lymphocytes, Neutrophil, Monocytes and Basophils counts in healthy and nematodes infected sheep groups. Fourth experiment was conducted on assessing the comparative efficacy of synthetic (Oxfendazole and Ivermectin) and locally manufactured herbal medicine (Deedani, Kirmar and Atreefal Deedan) anthelmintics against sheep nematodes at AZRC/PARC Range-livestock Research Station Sanjavi district Ziarat. The present study results regarding the comparative efficacy showed that, Atreefal deedan among herbal products (Deedani and Kirmar) and Ivermectin than Oxfendazole was found effective against sheep nematodes. The sheep treated with Ivermectin showed highest (96%) FEC reduction, followed by Oxfendazole/Atreefal deedan (86%), Kirmar (60%) and Deedani (32%).

Material type: book Book; Format: print Publisher: 2011Dissertation note: Cryptosporidiosis is an important parasitic infection of cattle, buffaloes, goats, sheep, horses, cats, human beings and other vertebrates. Prevalence of Cryptosporidiosis in selected animals and human beings carried out on the basis of microscopic examination and polymerase chain reaction (PCR). Percent prevalence of Cryptosporidiosis determined on the basis of conventional identification method was highest in calves (23.1) followed by cattle (10.5) and buffaloes (8.47). Percent prevalence of Cryptosporidiosis in calves, cattle and buffaloes was higher at Government dairy farm (38.33, 20.55 and 16.66) followed by Gawala colonies (26.1, 12.77 and 9.44), Military dairy farm (18.3, 6.11 and 4.44) and then House hold dairies (10, 3.88 and 3.34). Percent prevalence recorded in calves having age less than six months was higher (26.45) than those with 7-12 months of age (16.6). Percent prevalence of Cryptosporidiosis in cattle having age of 2-3 years was higher than those cattle having 3-7 years of age. Similarly, infection rate was higher in buffaloes with 2-3 years age (11.8) than 3-7 years (9.8). Cryptosporidiosis percent prevalence recorded in female calves was higher (24.04) than male calves (18.2). Percent prevalence of Cryptosporidium oocysts observed in feces of male cattle was little higher (11.25) than female cattle (10.4). Cryptosporidiosis percent prevalence recorded in female buffaloes was higher (13.3) than male buffaloes (8.3). The data was analyzed monthly for the purpose to trace out the specific period of the year having the highest prevalence rate of Cryptosporidium infection. The highest percent prevalence of Cryptosporidiosis recorded in fecal samples of calves was during summer (27.5) followed by autumn (25.8), spring (20.3) and the lowest in winter season (14.5). Overall the highest percent prevalence of Cryptosporidiosis in cattle recorded was during summer (15), followed by spring/autumn (10.88) and the lowest in winter (6.6%). The highest percent prevalence of Cryptosporidiosis recorded in buffaloes was during summer (12) followed by autumn (20), spring (7.5) and the lowest in winter season (4.5). In human beings patients suffering from diarrhea were examined by microscopy and percent prevalence calculated was 40 in present study. Molecular percent prevalence rate determined was 12.22 in cattle. Percent prevalence recorded using PCR was the highest at Government dairy farm (22.7), followed by Gawala colonies (14.41), Military dairy farm (7.7) and the lowest at House hold dairies (5). The highest season wise percent molecular prevalence was observed during summer (16.6) followed by autumn/spring (13.3), the lowest in winter (7.7). The higher molecular percent prevalence in young cattle (2-3 years) was higher (23.7) than those having age between 3-7 years (10.7). Molecular percent prevalence of Cryptosporidiosis in selected cattle was lower in females (13.6) than males (15). The efficacy of albendazole observed was 43.05, 58.7 and 64.6 percents on 13th, 20th and 27th day post treatment. The efficacy of albendazole determined on this dose was 34.8, 57.1 and 62.9 percents on days 13, 20 and 27 post therapy. Efficacy of drug calculated on days 13, 20 and 27 was 32.8, 53.3 and 56.6 percent, respectively. Percent efficacy of used drug was 55.04, 68.5 and 79.4 on days 13, 20 and 27 post treatment, respectively. At 50mg/kg body weight dose rate of paromomycin significant decrease in OPG count was recorded from 6th day post treatment and onward (P<0.05). On days 13, 20 and 27 percent efficacy of used drug determined was 48.1, 65 and 69, respectively. Availability: Items available for loan: UVAS Library [Call number: 1678,T] (1).

20. Serodiagnosis, Epidemiology And Economic Improtance Of Hypodermosis In Goats In Balochistan

by Saadullah Jan | Dr. Mohammad Lateef | Prof. Dr | Prof. Dr. Azhar Maqbool.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2013Dissertation note: Hypodermosis is an endemic infestation of cattle and goats in Pakistan. It is caused by H. lineatum and H. bovis in cattle and P. silenus in goats and is commonly existed species in Pakistan which belong to order Diptera, family Oestridae. The larvae of these flies are obligatory parasites of their hosts and are economically very important causing severe damage to the skins/hides effecting leather industry. Goat warble fly infestation has severe economic impact on tanning industries and it also causes growth retardation, carcass depreciation and production losses of milk and meat. Keeping in view the importance of this infestation, studies were designed on serodiagnosis, epidemiology and economic importance of hypodermosis in goats in northern uplands of Balochistan, Pakistan, with the objectives to diagnose warble fly infestation at early stages through serology for better control and eradication strategies, to study different epidemiological factors (age, sex, breed, temperature, humidity and rain fall) contributing goat warble fly infestation in the study areas, to compare seroprevalance over the prevalence based on clinical examination and to study the economic importance of hypodermosis in Loralai, Ziarat and Pishin districts of Balochistan, Pakistan. The duration of the study was one year commenced from April 2011 to March 2012. The most prevalent breed of goat i.e. khurasani breed in uplands of Balochistan was involved in the study which was compared with the Non-descriptive breed of goats. It is expected that the result of this study will be helpful to plan better control and eradication measures of warble fly by providing the base line data for further improvement in livestock sector in Balochistan. Serological studies for an early diagnosis and seroprevalence of hypodermosis were carried out by commercial ELISA kit (IDEXX hypodermosis serum antibody test) method. A total of 1440 blood samples were collected during the study. Sera were separated and stored at - 20 °C until further use. The infestation was detected in May and June (summer) where as the infestation is usually detected clinically in the months of October until February (winter) when warbles appear on the back and flank regions of the animals. ELISA based seroprevalence showed the highest mean percentage (48.45 %) of goat warble fly infestation in all the three districts, while the mean percentage by clinical palpation method was 15.94 % in all the three districts. In the slaughter house and skin market studies the mean percentages of goat hypodermosis were 9.07 % and 7.16 %, respectively. In the study of epidemiology, a total of 8640 number (2880 number per district) of goats of different age, sex and breed were examined on monthly bases by hand palpation clinico-parasitological method for the presence and prevalence of hypoderma infestation in the field animals. The mean prevalence percentage was 15.94 % i.e. 10%, 21.25% and 16.59% in Loralai, Ziarat and Pishin districts, respectively. In the study conducted in slaughter houses of all the three districts, a total of 4320 number (1440 number per district, 120 animals per month per district) of goats of different age, sex and breed were examined and the prevalence was recorded. Three age groups were selected for both the studies i.e. < 1year, 1-2 year and > 2 year old. The larvae were collected from naturally infested animals for identification. The mean prevalence percentage of hypodermosis in the slaughtered animals was 9.07 % i.e. 4.86%, 12.56% and 9.79% in Loralai, Ziarat and Pishin districts, respectively. Analysis of data by Pearson Chi-square test (?2) revealed highly significant difference (P<0.05) in the overall prevalence of hypodermosis district-wise in the fields and slaughter houses. Results were processed using Microsoft Excel 2007. In comparison of the fields and slaughter houses, the prevalence was significantly higher in the field animals as compared with the slaughterhouse animals in all the districts. In the study based on examination of the infested skin in the skin markets, a total of 3600 numbers of skins of goats (1200 numbers per district, 100 skins per month regardless of age, sex and breed) were examined by making monthly visits to the skin markets of each district. The intensity of the infection was also recorded by counting the number of holes in each infected skin. The overall district-wise mean prevalence percentage was 7.16 % and the mean intensity was 16.19 holes per skin. Analysis of data of the skin market by Pearson Chi-square test, using SPSS version 16, revealed highly significant differences (P< 0.05) in the prevalence of hypodermosis district-wise. Month-wise prevalence in the field animals showed that the highest prevalence was during January and lowest during October in Loralai, Ziarat and Pishin districts. In the slaughter house study, highest prevalence was observed during October and the lowest during July in Loralai district, highest during January and the lowest during July in Ziarat district whereas the highest prevalence was during the month of November and the lowest during July in district Pishin. Month-wise analysis of data by Pearson Chi-square test, using SPSS version 16, revealed highly significant differences (P< 0.05) in the prevalence of hypodermosis both in the field as well as in the slaughter house studies. Age-wise prevalence in the field as well as in the slaughter house animals showed the highest prevalence in the age group of 1-2 years as compared to the age groups of < 1 year and > 2 years. Analysis of data by Pearson Chi-square test, using SPSS version 16, revealed highly significant differences (P< 0.05) in the prevalence of hypodermosis amongst age groups both in the field as well as in the slaughter house studies. No significant difference was observed sex-wise and breed-wise in both the studies of fields and slaughter houses of the study areas. The life cycle pattern in naturally infested goats with warble fly was studied in the fields and slaughter houses of the study areas from April 2011 to March 2012. All the observations regarding the life cycle stages were recorded. First instars larvae (L1) were observed in subcutaneous tissues from mid of May to mid of July in slaughter houses of the study areas. Second instars larvae (L2) were observed in the slaughter houses from mid of July to November. Third instars larvae (L3), as well developed warbles on the back and flank regions of the goats, were palpated in the field animals and observed in the slaughter houses from December until the end of February. The pupal period was observed in early spring in the months from March to mid of April. No larvae were observed in the slaughter houses and fields of the study areas during this period while the adult fly activity season (Oviposition period) was observed in early summer from mid of April to mid of May. The estimation of economic losses due to skin damages were determined by multiplying the estimated infested numbers of skins with the value of loss per skin. The overall losses due to warble fly infestation in the study areas were calculated as Pak. Rupees 7578625.49 (Pak. Rs 7.57 million = US$ 77530.69, US$ 1= Rs. 97.75) annually. Based on the early detection studies, it is concluded and recommended that the best time for the treatment of goat warble fly infestation in uplands of Balochistan is in the months of June and July when first larval instars are still in migratory stage and not yet have reached their final sites on the back and flank regions of goats to cause damage to the skin, where as the farmers usually treat their animals against warble fly in the winter season when they observe the warbles on the backs of the animals but at that stage the larvae have damaged the skins of the animals.

21. Comparative Efficacy Of Different Diagnostic Techniques For Ovine Haemonchosis Through Faecal

by Sadaf Anwar | Dr. Muhammad Lateef | Dr. Aftab | Prof. Dr. Azhar Maqbool.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2013Dissertation note: Livestock plays pivotal role in the economy of country and small ruminants are the major source of food products for human. Haemonchus contortus is the most significant parasite of small ruminants and cause heavy production losses by causing reduction in meat and wool production. The parasite directly affects the health of an animal and causes anemia, hemorrhages, anorexia, weight loss and death of affected animal. This study was designed to diagnose the Haemonchosis in sheep in and around Lahore. The accurate diagnoses of the parasite are important for its control and treatment. Direct smear, floatation technique and Polymerase Chain Reaction (PCR) were applied to check the sensitivity and specificity in diagnosing Haemonchosis in sheep. For this purpose 100 faecal samples were collected randomly from different areas of Lahore. Each faecal sample was examined by direct smear method and floatation technique. Out of 100 faecal samples 44 were microscopically positive. 30 by direct smear method and 44 by floatation technique. Specific primers were designed to diagnose Haemonchosis in sheep by using ITS-2 Region. 44 microscopically positive samples were confirmed by PCR. 29 (66%) samples were found to be PCR-positive and 15 (34%) were found to be PCR-negative. Several other species of parasites were also found during microscopic examination of faecal samples. Two samples wetre found positive for coccidial oocyst and seven samples were also positive for other nematodes along with Haemonchus spp. Flotation technique was found to be superior in diagnosis of Haemonchosis as compared to direct smear. Conclusion: From current study it is concluded that Haemonchosis is widely prevalent in ovines. Its accurate diagnosis is essential for the treatment of infectious diseases and control of this parasite. Molecular technique has the advantage over conventional diagnostic techniques because PCR is more specific than conventional methods of diagnosis. According to the present study by conventional method there is 34% error chances to diagnose other Trichstrongylid eggs as Haemochus spp. The main advantage of using PCR as diagnostic test, are an increased speed of diagnosting the disease and its capability to notice low worm burden in small volume of faeces from individual animals.

by Muhammad Irfan Zahid (2011-VA-800 | Prof. Dr. Azhar Maqbool | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr.Shazia Anjum | Prof. Dr. Kamran Ashraf.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2015Dissertation note: A camel is a very hardy ruminant animal, which can survive under harsh climatic conditions very effectively by utilizing the marginal areas with excellent capabilities and produce under such conditions (Hjort and Hussein, 1986; Abbas and Tilley, 1990). Camel is an important animal as it is well adopted in unique manners in the hot, arid and semi-arid environments (Schwartz, 1992). It can survive without water and food for many days and this unique ability of camel makes it an ideal for such harsh conditions for which it is also commonly known as “The Desert Ship”. In spite of the fact that camel is an important member of a group of animals which produces food for human consumption in the shape of milk and meat, yet it is the most neglected one in the field of scientific research. It may be due to the fact that camel belongs to such areas of the world which are arid, semi-arid or rain fed in nature, having harsh climatic conditions, where poor nutrition and poor management are the major issues (Sohail, 1983). It is an established fact that diseases originating from parasites lead to the main health hazard issues in animals. These parasites survive at the expense of the host animals causing lot of health problems, like skin irritation, anemia leading to weakness and debility. Some of the parasites have zoonotic importance and may become a source for the transfer of many contagious diseases like scabies to the human beings (Dominguez et al. 1978). McClain et al. 2009, observed the scabies as a major health problem globally both for humans and animal population. Sarcoptes scabiei is an ectoparasite which is a cause of scabies, a skin problem in the human beings worldwide and the similar species of mites do also produce a similar type of disease in a large variety of wild and domesticated mammals (Pence and Ueckermann, 2002; Fitzgerald et al. 2004). Fain, 1978, reported that more than fifteen (15) different species of Sarcoptes scabiei morphologically and genetically distinct from each other have been identified in different hosts. Introduction 2 Sarcoptic mange is the second important problematic disease of camel after Trypanosomiasis (Nayel and Abu-Samra, 1986). Scabies caused by Sarcoptes scabiei var cameli is a serious & highly contagious skin problem and also economically important disease of the camels (Pegram and Higgins, 1992). Camels, which are reared with deficient nutrition, poor management and under unhygienic conditions are mostly affected by this disease (Kumar et al. 1992). A large group of people and communities living in arid diverse ecozones in the entire world, particularly in harsh climates earns their livelihoods by depending on camels. This dependence may spread to the utilization of camel milk, meat, wool and leather besides its use in transportation, riding and sports (Wilson, 1984; Snow et al. 1992). In Pakistan camels are also raised by the people for meat, milk, riding, transportation and sports purposes in the deserts, semi desert & rain-fed / warm areas of the entire country being a hardy animal as it can tolerate easily the rugged climate as well as extremes of temperatures of such areas. The natural harsh and adverse climatic conditions, particularly during long dry seasons lead to a paucity of feeding regimes resultantly the camels raised in such areas are subjected to stress conditions which lower their resistance and make them easily vulnerable to diseases (Abbas et al. 1993; Agab, 1993). Abbas & Tilley, 1990; Saint-Martin et al. 1992; Abbas and Agab, 2002; Pathak and Chhabra, 2010; while reviewing the parasites & parasitic diseases of camel population in India were of the opinion that Sarcoptic mange is a serious, debilitating, dreaded and widely prevalent disease of camels in India. Besides other infectious diseases of bacterial and viral origin, camels are exposed to a wide range of internal & external parasitic infestations. Amongst other so many external parasites to which camels are exposed, the Sarcoptic mange is recognized to be one of the most Introduction 3 serious and damaging disease. This disease is caused by a mite known as Sarcoptes scabiei var cameli which belongs to genus Camelus of SARCOPTIDAE family in Veterinary Entomology. It is an extremely pruritic, contagious and debilitating skin disease which is very frequently and sudden in onset. It is also ranked as one of the most serious and important disease of the camels. Sarcoptic mange infestation is very common in the areas of thin skin, the head, neck, flanks, medial aspect of thighs or inguinal region, mammary glands and prepuce. The head is usually affected very rapidly as the animal uses its teeth for scratching the affected areas. Besides linking the occurrence of the disease with poor camel management, malnutrition and contact with infected objects, the stray & infected camels also often become a focus of infecting the healthy animals when mingling with them particularly at watering places for drinking purpose (Richard, 1987; Abdel-Rehman et al. 2001). Sarcoptes is a burrowing mite as it penetrates deeply through the skin surface of the infected camel. This burrowing of mites in the skin helps these parasites lead to intense pruritus and exudative dermatitis. In pruritus, mites penetrate deep into muscular areas, damaging the flesh and lowering the quality of meat. The early inflammatory reaction of the host body towards the mites becomes evident in the shape of small popular elevations, invasion and injuries leading to formation of hairless areas, scaly crust formation or scabs on the affected parts and the skin become dark and thickened. Skin of mangy camel show hemorrhages, and subcutaneous odema after the development of fissures in the underlying epidermis (Kumar et al. 1992; Amer et al. 2006). The fertilized female mites create winding burrows or tunnels in the upper layers of the epidermis of the skin of the host animal and feeding on the serous exudate, a liquid oozing from the damaged tissues. The female mites lay about 40-50 fertilized eggs in these tunnels which Introduction 4 hatch in 3-5 days into a six legged larvae. These larvae immediately crawl to the surface and burrow themselves in the superficial layers of the skin and create small molting pockets. In these molting pockets, the larvae molt to next stages of nymph and adult. The adult male then emerges and seeks a female either in the molting pocket or on the surface of skin. After fertilization the female produces new tunnels, either de novo or, by extension, of the molting pockets, lays eggs in these tunnels and a new life cycle starts. The entire life cycle of Sarcoptic mange is completed in 17-21 days. New hosts can be infected through direct transmission by contact between the animals, presumably from larvae, nymph or adult mites, which are commonly present on the skin surface of the infected animal. Indirect transmission of infestation can also take place through the objects or fomites having mange infection, which come into contact with the affected camel, such as harnesses, blankets, baggage tack, tents and tree trunks (Richards, 1987). The pruritus increases as the mites penetrate deeper in the skin (Al-Rawashdeh et al. 2000, Driot et al. 2011, Bekele et al. 2012). Based on the rate of infection camels can be seriously disturbed by the Sarcoptic infestation as they may stop grazing which can lead to a rapid fall in milk production, and deterioration of health condition. With the increase in the irritation due to scabies, the camel rubs, bites and scratches the affected areas in an attempt to reduce the itchiness. Due to rubbing, biting or scratching, the mites move to the periphery affecting the healthy tissues and resultantly affected area spreads. As the disease prolongs, the skin becomes excoriated, leading to hair loss and the development of scabs. These scabs in turn may be rubbed away and a red surface developed. The animal becomes restless due to severe Sarcoptic mange infestation and involvement of most of the body surface. If the diseased animal is not treated in time, the animal loses its health condition, become emaciated and within two, three weeks the acute stage of Introduction 5 disease may give way to more chronic state (Gorakh et al. 2000, Abubakar et al. 2002, Driot et al. 2011). Sarcoptic mites rarely survive long off the host under natural conditions. A continuous direct contact of animal keepers with their camels can also lead to transmission of diseased condition in human beings which is termed as pseudo scabies. Transmission of infection from camel to man usually takes place during milking, handling or riding. The main symptoms of pseudo scabies can therefore be seen in the inter digital spaces of the hands, on the wrists, forearms, the elbows, the axillary folds and inner side of the thighs. Once a herd is infected with Sarcoptic mange, continuous reinfection of the disease occurs (Schillinger 1987, Singh & Veer 2005, Premalatha et al. 2010). Sarcoptic mange is usually considered to be a seasonal disease and is often reported severe during the winter months as in cold weather the disease had an acute course. However, there is some evidence that in some countries hot weather predisposes to acute outbreaks of camel mange and in the cooler, winter season the rate of mange infestations are at the lowest. In the summer the activity of the mite seems to decline or disease becomes chronic. Dietary intake is an important factor in mange infestation. Nomadic camels on a low nutrition plan, probably carrying heavy worm burdens in hot desert conditions are likely, therefore, to be highly prone to Sarcoptes at this time (Dinka et al, 2010). During such periods of great activity, the mites are readily transmissible from one animal to other animals (Richards, 1987, Banaja & Ghandour, 1994, Tefera & Gebreah, 2001). Mange can easily be diagnosed clinically from the occurrence of pruritus, depilation, alopecia, thickened skin, folds around the joints and encrusted plaques being the main characteristics of this parasitosis. In order to control this zoonotic disease, it is essential to treat Introduction 6 both camel and man along with effective checks over other predisposing factors of the disease such as hygiene and nutritional requirements of the animals. The skin diseases like the scabies both in human beings and animals are being treated with a variety of allopathic drugs now a day, but the role of herbal plants in use since centuries in different shapes cannot be ignored at all, especially in the rural lifestyle. Further with the continuous use of different acaricidal drugs, the issue of resistance development has come across as a challenge for the researchers to find some alternatives for the purpose. Accordingly the research work on the use of traditional herbal medicines is gaining attention day by day. Although there are many reports and studies regarding the prevalence of Sarcoptic mange in camel from different parts of the world, only few preliminary reports are available for Pakistan and none of them provide detailed epidemiology of Sarcoptic mange and its effect on host health. Therefore, keeping in view the importance of the mange problem in camel population of the country, the present project was designed to determine the prevalence of Sarcoptic mange infestation, factors in its occurrence its zoonotic importance, effect on blood physiology and different treatment options in the camel population of Punjab, province in Pakistan.

Material type: book Book; Literary form: not fiction Publisher: 2014Dissertation note: Helminthiasis is among the most significant animal health harms, which inflicts heavy production and economy losses especially in small ruminants. The helminth problem is highly common mainly in developing countries like Pakistan (Dhar et al. 1982). Small ruminants have much importance in meat and leather industry of Pakistan. Sheep play a vital role in producing income and provide financial support for poor farmers in developing countries. Endo-parasites represent a major constraint to the production and growth of small ruminants (Babar et al. 2013). Pakistan has been reported to problem of helminths in sheep and goat (Raza et al. 2009) and cattle and buffalo (Athar et al. 2011). Mainly infection is generally controlled by allopathic drugs and vaccination (Behnke et al. 2008). Parasitic diseases are a major threat in efficiency, the most widespread helminth parasites being Haemonchus contortus, Trichostrongylus spp. and Oesophagostomum columbianum. Liver flukes and paramphistomes (Fasciola gigantica and Paramphistomum microbothrium) occasionally cause heavy mortality in animals grazing swampy areas (Akerejola et al. 1979). The adverse effects of nematode infections include: loss of weight, anorexia, anaemia, retarded growth, delayed sexual maturity, decrease in milk and meat production (Saddiqi et al. 2012). Indigenous knowledge of herbal medicine is a big source of the modern knowledge. Today, thousands of plants, traditionally used as medicines are being explored (Kakar, 2012). Chemical control of helminths coupled with improved management has been an important worm control approach throughout the World. However, increasing problems of development of resistance in helminths rise in price of drugs contributing factor for traditional plant used (Coles et al. 1997) against anthelmintics have led to the proposal of screening medicinal 1 Introduction plants for their anthelmintic activities. Reports of drug resistance have been made in every livestock host and to every anthelmintic class. In some regions of world, the extremely high prevalence of multi-drug resistance (MDR) in nematodes of sheep and goats threatens the viability of small-ruminant industries. Many parasitic nematodes of veterinary importance have genetic features that favor the development of anthelmintic resistance (Kaplan et al. 2004). The plants are known to provide a rich source of botanical anthelmintics (Lewis and Elvin Lewis 1977). There are many medicinal plants have been used to treat parasitic infections in man and animals (Iqbal et al. 2005). Various botanical plants have been possessed anthelmintic activity against helminth e.g Chenopodium album (Eguale & Giday, 2009). It has been expected that there are around 250,000 plant species present throughout the world. Plants, from ancient, have served human beings as sources of food, shelter, clothing and medicines. Before the advent of modern allopathic medicine and synthetic drugs, plants and to a certain extent, animals and minerals were used in various formulations for treatment of diseases by traditional medicinal practitioner (Rahmatullah et al. 2011). Plant medicine is very important from ancient to present daytime. The uses of biologically different plant assets for various ailments are the lifelong struggle of humankind (Hussain et al. 2008). In Indo-Pak subcontinent, Ayurvedic and Unani therapeutic systems are very popular and people have been using plants not only for the treatment of their own ailments but also for their domesticated animals. Chenopodium album (Chenopodiaceae) commonly known as “Bathu” is important medicinal plants in Pakistan and their different parts are utilized in the traditional system of medicine (Said et al. 1970). Chenopodium album usually recognized as “Bathua” is a familiar food as well as a medicinal plant. In traditional system of medicine, it is used as an anthelmintic, antimicrobial, antirheumatic, contraceptive, laxative, cardiotonic, antiscorbutic, 2 Introduction and blood purifier & also in management of hepatic disorder, spleen enlargement, intestinal ulcers, digestive, carminative, seminal weakness, pharyngopathy, splenopathy, hemorrhoids, cardiac disorder (Panigrahy et al. 2012). The seeds of the plant are known to possess anthelmintic activity against Haemonchus contortus. A compound C37- trihydroxy adjacent bistetrahydrofuran acetogenin, present in the seeds, is responsible for inhibition of the egg hatching of gastrointestinal nematodes (Saha et al. 2011). Chenopodium album (Chenopodiaceae) is a rapid rising fragile annual plant and it is found in Bangladesh. In English plant known as Lamb’s quarters and in Bengali as Buthiya shak. Both in vitro and in vivo activity of plant as anthelmintic has been reported (Jain and Singhai 2012). Chenopodium album was found to be one of the initial plant species colonizing a heavy metal-contaminated site, polluted by pyritic (sulphide-rich) waste from the Aznalcóllar Mine spill (South-western Spain). This shows its importance in the re-vegetation of this soil (Walker et al. 2004). In vitro experiments were arranged to conclude the possible anthelmintic efficacy of crude aqueous extracts and powder of the whole of Chenopodium album (Eguale et al. 2009). Commercial preparations of oil of chenopodium album and its active constituent, ascaridol, obtained by steam distillation, have been and continue to be, used with substantial success in mass treatment campaigns (Kliks et al. 1985).

32. Development Of Molecular Techniques For The Detection Of Toxocara Species In Dog

by Suleman Shah (2013-VA-783) | Dr.Nisar Ahmed | Prof. Dr. Azhar Maqbool | Dr. Nauman Zahid .

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Genus Toxocara belongs to sub-family Ascaridoidea. The genus contains species of significant importance for human and animal health (Despommier, 2003; Lee et al., 2010; Rubinsky-Elefant et al., 2010) . Various species of the genus Ascaris, Toxocara canis, Toxocara cati and Toxocara malaysiensis, are clinically important to cause diseases in mammals that are usually canids and felids (Fisher, 2003; Lee et al., 2010). Toxocara canis and T. cati are of zoonotic importance. (Fillaux et al., 2013). This parasite has a fecal-oral type of transmission. Dogs are its definitive host and humans are its accidental hosts. Its eggs are non-infective when eliminated with feces of dogs. Eggs then develop into infective embryonated stage. The duration of embryo development depends upon different environmental factors such as temperature, humidity and type of soil (Overgaauw et al., 2013). Soil of the parks, streets and other public places polluted with the feces of stray dogs and cats also play a great role in the transmission of toxocariosis to humans. Toxocara spp. have the ability to reproduce and survive for long time periods outside their host. In this way the lands of parks, streets and other public places remain infected for long times. This contaminated soil with Toxocara eggs poses a high risk of infection to humans. Specially children under 5 years of age are the key set affected because they play in playgrounds and by chance can swallow the eggs of these intestinal parasites from contaminated soil (Dado et al., 2012; Thomas et al., 2014). Infection commences both in man and dogs by ingestion of embryonated eggs, which are then hatched to liberate larvae. Humans get infected by the accidental ingestion of infective eggs with contaminated food or water. Eggs hatch in the stomach and larvae move to the small intestine. From small intestine these larvae migrate to visceral organs via blood causing a series of to retina via retinal artery and impair eye vision (Nicoletti, 2013). In dogs, these larvae mature within the small intestine. Then, mating takes place and new non-embryonated eggs are formed (Despommier, 2003). Humans can acquire infection by infective embryonated infections (Rubinsky-Elefant et al., 2010). Clinical signs of the infection varies from asymptomatic to a range of severe infections i-e. Visceral organ damage (Fillaux et al.) by the migration of larvae of T. canis and T. cati. These larvae cause Ocular larva migrans by the migration of larvae eggs from adulterate soil, dirty hands, un-cooked vegetables and by direct exposure to pets (Good et al., 2004; Wolfe et al., 2003). Nearly 100% of pups are infected in utero by reactivated somatic larvae from day 42 of the gestation period. This trans-placental path and intra uterine infection is the most important means of transmission in pups (Overgaauw et al., 2013). Zoonotic prevalence is higher in tropical region than in temperate regions. Rural populations consume more risks of infection as compared to urban population of same area (Rubinsky-Elefant et al., 2010). Worldwide surveys show that the prevalence of Toxocara infection ranges from 86% to 100% in pups and 3% to 81% in adult dogs. Infection rate is higher in pups between age of 1-6 months as compared to dogs more than 7 months old (Itoh et al., 2004). In Lahore, prevalence of Toxocara infection is 49% in stray dogs and 30% in pet dogs (Chattha et al., 2009). Various diagnostic methods are employed for diagnosis of Toxocara species. Coproscopical techniques are classical techniques which are extensively used to identify eggs and larvae in fecal samples based upon morphological characteristics, coproscopic techniques have been extensively used to diagnose larvae and eggs in fecal samples (Sweeny et al., 2011). But identification by these coproscopic techniques has limitation in the differentiation of different species of Toxocara (Li et al., 2007a). Immunodiagnostic approaches like ELISA have also been utilized by using excretory/secretory antigens of larvae (Fan et al., 2004). But it has drawback that there is chance of cross reaction between anti-toxocara serum and antigen from other Toxocara spp. (Lozano et al., 2004). Alternatively, the DNA based molecular approaches are being employed for the accurate diagnosis of toxocariosis at species level. This technique may overcome the drawbacks of traditional methodologies and help in molecular epidemiological screening because genetic variation can be studied. Molecular methods based on DNA are more sensitive and specific as compared to classical methods (Jacobs et al., 1997; Ndao, 2009). In Pakistan, DNA based diagnosis of Toxocara spp. has not been employed yet. The present study was designed to achieve the goal of accurate diagnosis of prevalent species of Toxocara in dogs by using effective DNA based diagnostic technique.

34. Taxonomy And Control Of Flea Infestation In Cats At Lahore

by Umair Tariq (2008-VA-233) | Dr. Nisar Ahmad | Prof. Dr. Azhar Maqbool | Dr. Syed Saleem Ahmad.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: INTRODUCTION Fleas play an important role in causing clinical skin disorders and diseases transmission in man and pets animals (Rust & Dryden, 1997). Fleas are one of the most important ectoparasites with more than 2,000 species worldwide affecting mammals, birds, and reptiles (Hsu, 2003). In some locations, fleas represent over 50% of all the dermatological cases presented to small animal clinics. Most are limited to hosts with nests as this can provide conditions for the completion of their life cycle (Linardi & de Avelar, 2014). While fleas on pets are generally considered a nuisance that may cause some dermatologic problems, they are also responsible for the transmission of several important diseases in humans and animals (Dryden & Rust, 1994). They have been involved in transmission of cat scratch disease (Bartonella henselae) (Chomel et al., 2006; Comer et al., 2001), Rickettsia typhi (Murine thyphus), Rickettsia felis (Finkelstein et al., 2002; Rolain et al., 2005), and also serve as the intermediate host for the tapeworm Dipylidium caninum (Rust & Dryden, 1997) and several trypanosomatids (Coutinho & Linardi, 2007). The term ‘‘cat flea,’’ which is the approved common name for Ctenocephalides felis felis (C. f felis), can occasionally cause confusion. When it appears in print, it refers to the specific flea genus and species and not to fleas recovered from cats. There are four recognized subspecies of C. felis throughout the world: Ctenocephalides felis damarensis and C. felis strongylus occur primarily in East Africa, C felis orientis occurs in India and Australia, and the widespread C. f felis occurs in all continents except Antarctica and is the only subspecies that occurs in North America (Rust & Dryden, 1997). The cat flea, C. felis, is a clinically important parasite of domestic pets, being responsible for the production of allergic dermatitis, serving as the vector of Introduction 2 various bacterial pathogens, and being the intermediate host for filarid and cestode parasites. Flea allergy dermatitis is the most common dermatologic disease of dogs and a major cause of feline miliary dermatitis (Dryden & Rust, 1994; Rust & Dryden, 1997). Clinical features vary from asymptomatic to severe hypersensitivity reactions with restlessness, alopecia from scratching and biting resulting in a pruritic papular dermatitis. Vacuuming of carpets, furniture cushions, rugs, or other substrata, with a vacuum machine containing a ‘‘beater bar,’’ will remove many of the flea eggs and larvae. In addition, cocooned pupae at the upper levels of the carpet can also be affected. The vibration also stimulates adult fleas to emerge from their cocoons so that they can be collected in the vacuum machine. Therefore frequent vacuuming, during a flea infestation, can reduce the overall flea burden in the home. It should be ensured that vacuum bags are disposed of properly, to prevent recolonization of the home with flea stages previously removed by vacuuming. Because outdoor development of immature flea life stages is limited to shaded areas, altering outdoor environments to eliminate such habitats can effectively reduce flea populations. Because urban wildlife, such as opossums, raccoons, and foxes, are good hosts for cat fleas, pet owners should avoid encouraging visitations by wildlife, which will affect flea and tick control (see later discussion). Treatment of indoor and outdoor environments with insecticides requires knowledge of what to use and where to use it. For this reason, it is suggested that pet owners consult with a licensed pest control specialist for such applications (Angelbeck-Schulze et al., 2014; Perrins & Hendricks, 2007). In line with increasing urbanization over the last few decades, flea species that infest pets have become household pests. Thus, and for reasons of animal and human welfare, the control of fleas is of great importance worldwide. Despite the increase in the number of products available and Introduction 3 their use, flea infestation of cats and dogs is still widespread in Europe and on other continents, whereas resistance of these insects against many chemicals has been detected (El-Gazzar et al., 1986). Cat fleas are the most important ectoparasite of cats and dogs worldwide. During the past ten years, topical and oral applications of insecticides such as fipronil, imidacloprid, lufenuron and, most recently, selamectin have revolutionized cat-flea control. Recent studies show that these therapies eliminate the need to treat indoor and outdoor environments, and their use markedly reduces the severity and prevalence of flea allergic dermatitis. Surveys have yet to reveal the development of insecticide resistance to these chemical compounds. Extending the longevity of these effective host-targeted therapies should be a major goal of the veterinary community (Rust, 2005).

by Fariha Mariam (2008-VA-97) | Dr. Muhammad Ijaz | Dr. Khalid Mehmood | Prof. Dr.Muhammad Sarwar Khan | Prof. Dr. Azhar Maqbool .

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2015Dissertation note: Gastrointestinal helminths are responsible for wide range of health problems, economic losses in camels and are characterized by impaired milk, meat, infertility, low calving rates, decreased working efficiency and even death of the camel. To study the gastrointestinal helminths, 384 camels of different age, sex and breed was examined coprologically. For this, five gram of fresh fecal sample was carefully collected into a sealed container from each camel and was transferred to Medicine lab, UVAS, Lahore in containers with ice packs. Fecal samples were scored 1-3 based on the consistency. The individual samples was triturated in saturated salt solution, sieved and examined for helminths eggs by using different techniques i.e. Direct Smear Method, Sedimentation technique and Floatation technique while the eggs count was performed by McMaster technique. Among the camel population, the current study indicates that in Marrecha breed the prevalence of Nematodes was Trichostrongylus 1.77%, Haemonchus 8.44%, Nematodirus 3.11% and Trichuris 7.11% respectively. Mixed infestation of all the nematodes was found 26.66% in infested camels, while the prevalence of Camelostrongylus, Trichostrongylus, Strongyloides, Haemonchus, Nematodirus and Trichuris in Barella breed was 4.40%, 1.88%, 2.51%, 6.91%, 2.51% and 7.54% respectively. Mixed infestation of all the nematodes was found 25.78% in infested camels. The prevalence of Fasciola hepatica was found higher in Marrecha breed as compared to Berrela breed. It was 18.66% in Marrecha breed and 14.46% in Barella breed while the overall prevalence of Fasciola hepatica in the camels irrespective of the breeds was 16.93%. While the prevalence of Fasciola gigantica was also found higher in Marrecha breed than Barella breed. It was 16% in Marrecha breed and 10.69% in Barella breed while the overall prevalence of Fasciola gigantic in the camels irrespective of the breeds was 13.80%. The overall prevalence of fascioliosis in camel is 30.31. The prevalence of Moniezia expansa was found higher in Marrecha breed as compared to Barella breed. It was 10.22% in Marrecha breed and 8.80% in Barella breed while the overall prevalence of Moniezia expansa in the camels irrespective of the breeds was 9.63%. The sex wise prevalence of gastrointestinal Nematodes in males was 39.28% which includes Camelostrongylus 8.03%, Trichostrongylus 3.57%, Strongyloides 6.25%, Haemonchus 11.60%, Nematodirus 4.46% and Trichuris 5.35% respectively while in the female it was 25.37% which includes Camelostrongylus 4.41%, Trichostrongylus 2.20%, Strongyloides 2.94%, Haemonchus 6.25%, Nematodirus 2.57% and Trichuris 6.98%. The overall prevalence of Nematodes in Male was found higher as compared to Female which was 39.28% and 25.37% respectively. Sex wise prevalence of GI Trematodes in Camels was determined through collected samples. The prevalence of Fasciola hepatica was found higher in Female as compared to Male. It was 16.91% in Female and 15.18 % in Male while the overall prevalence of Fasciola hepatica in the camels irrespective of the sex was 19.53%. The prevalence of Fasciola gigantica was also found higher in Female than Male. It was 12.13% in Female and 11.61% in Male while the overall prevalence of Fasciola gigantica in the camels irrespective of the sex was 11.98%. Sex wise prevalence of GI Cestodes in Camels was determined. The prevalence of Moniezia expansa was found higher in Female as compared to Male. It was 14.34% in Female and 13.39% in Male while the overall prevalence of Moniezia expansa in the camels irrespective of the sex was 14.06%. The overall prevalence of Nematodes in age group >10 yrs. was higher 30.25% as compared to age group 5-10 yrs. 20% which includes Camelostrongylus, Trichostrongylus, Strongyloides, Haemonchus, Nematodirus and Trichuris 3.36%, 2.52%, 6.72%, 5.88% 4.20% and 7.56 in age group >10 yrs and 1.88%, 1.51%, 1.88%, 4.90%, 2.64% and 7.16 respectively, in age group 5-10 yrs. The prevalence of Fasciola hepatica in age group 5-10 yrs was found higher as compared to age group >10 yrs. It was 30% in age group 5-10 yrs and 16.99% in age group >10 yrs while the overall prevalence of Fasciola hepatica in the camels irrespective of the age groups was 18.75%. The prevalence of Fasciola gigantica in age group 5-10 yrs was found higher as compared to age group >10 yrs. It was 9.33% in age group 5-10 yrs and 7.55% in age group >10 yrs while the overall prevalence of Fasciola gigantic in the camels irrespective of the age groups was 8.59%. The prevalence of Moniezia expansa in age group >10 yrs was found higher as compared to age group 5-10 yrs. It was 10.92% in age group >10 yrs and 10.18% in age group 5-10 yrs while the overall prevalence of in Moniezia expansa the camels irrespective of the age groups was 7.81%. To study the effect of gastrointestinal helminths on various blood parameters of camels, blood samples were collected from 5 infected and 5 healthy camels. Samples were analyzed using Hematology Analyzer and results were compared. For therapeutic trials, a total of 30 camels positive for helminths was taken and divided into three groups A-C each group comprising of 10 animals. A fourth group D was selected comprising of 10 uninfected camels. The camels of group A were treated with dry Neem (Azadirachta indica) leaf powder at a daily oral dose of 100 gm/camel for five days, group B was treated with Albenzole granules® (Albendazole) at a dose rate of 15mg/kg bd. wt. PO once. Group C (untreated) was designated as positive control, and the camels in Group D as negative control. Efficacy was determined on the reduction of eggs in feces at day 3, 7 and 14 (post-treatment). In the current study Neem leaves and Albendazole gave following results in the camels affected with Helminths. Neem leaves cured 20% of the animals on day 3rd after the drug administration while 40% and 60% of the animals cured on the day 7th and 14th respectively. Albendazole also gave good results against helminths affected camels. On the day 3rd of the treatment 30% animals cured while 60% animals were cured on the 7th day and on 14th day 80% animals recovered. Data regarding prevalence was measured by non-parametric, chi-square (χ2), while therapeutic trails were analyzed by repeated measures one way ANOVA, using SPSS (Statistical package for social sciences), P < 0.05 was considered significant.

39. Clinico-Epidemiological And Experimental Observations On Feline Lower Urinary Tract Disease Among Domesticated Cats

by Abeera Naureen (2007-VA-541) | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Azhar Maqbool.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Idiopathic Feline Lower Urinary Tract Disease (iFLUTD) has been known as a major as well as important problem throughout the world especially the veterinary profession. Nicks of this problem also found in Pakistan, however the veterinarians are usually unable to properly diagnose this disease due to lack of knowledge as well as the ancillary diagnostic equipment availability for this disease. Present study was divided into two phases. Phase – 1 included clinico-epidemiological data. To this end, target of more than 502 domesticated client-owned cats of either sex, age, breed, etc showing signs of feline lower urinary tract disease (FLUTD) as per Buffington (1994) were examined accordingly from 3 different cities (Lahore, Faisalabad, and Islamabad) of Pakistan). All data collected was based on a predesigned proforma by using structured interview of the owners. Diagnosis was solely based on serum-cortisol levels, urinalysis, radiography and ultrasonography. Phase II involved experimental trial. The data obtained from whole of the study was then presented in tabulated form as frequencies and percentages. Treatment and outcome of the disease were also analyzed accordingly. According to the present study conducted it is proved that iFLUTD is present among the cats in Pakistan. Its proper cognizance among the Pakistani veterinarians is still non-existent and is misdiagnosed as colic or constipation issues in cats. The present study was undertaken to bring iFLUTD into the reportive of small animal practitioners working in Pakistan. The present study debunked various previous notions like iFLUTD is associated with commercial diets and canned foods only if we talk about this region majority of cases were noticed that had home-cooked food given by the owner. Moreover, cases in Siamese breed are larger than Persian breed. It has been strongly associated with Indoor housing management. Additional work is still needed to explore untouched areas of epidemiology including factors other than those being studied in the previous literature. Academicians in veterinary pathology and veterinary medicine of Pakistani universities should embrace this malady in the Doctor of Veterinary Medicine (DVM) curricula. According to the present study results it is concluded that two factors like stress and pain accelerate the sympathetic nervous system outflow compared to normal felines leading to the inflammatory response. Thus the stress factor must be reduced in the form of making hiding places for cats at home to reduced down the fear factor along with enhancing the feeling of owes for that particular place. Moreover, some more practices should be performed by the owner to reduce down the stress factor like playing with the pet, giving full attention, placing toys and other attractive things like yarn balls at the feline places (where they live/placed). There was no significant difference found between the groups based on the food with health score along with the therapeutic judgment. Hence, it is recommended that more experiments should be performed on larger scale to assess GAG therapy on increased number of felines and need of hour is to conduct more veterinary studies to get information and authenticity for its use against iFLUTD. From this study conducted, I recommend to the owners that the cats must be provided with the indoor hiding places and play with their pets in order to reduce the stress factor that increases the risk of idiopathic lower urinary tract disease.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Theileriosis is the destructive disease caused by the protozoan in cattle. It is major cause of huge losses in production of cattle. It is a wide spread protozoan syndrome of cattle playing foremost role in production losses. Early and exact diagnosis of theileriosis can be helpful in reducing production losses. Early and exact diagnosis of theileriosis can be helpful in the control of disease.( Hypothesis ) Incidence of different Theileria species was recorded. Blood samples was collected in sterilized vacutainers. The samples were examined by preparing fresh blood smears followed by Giemsa staining and observing under microscope. Identification on preliminary basis was done by morphological characters of Theileria. In order to find the harmful effect of the theileriosis, blood hematology and biochemistry values were also be determined in both healthy and infected cattle. The samples from theileriosis positive animals were used for nucleic acid extraction. The extracted nucleic acid was amplified using Species specific primers.Agarose gel electrophoresis was used to visualize the amplified DNA. Amplicons of nucleic acid was treated with different restriction enzymes and pattern was visualized to find differences among different species of Theileria. Suitable statistical tool was used to analyze the data collected. Chi was applied on data by using statistical software SPSS version 20.0. This research will help to confirm for the conventional and molecular diagnosis of theileriosis in dairy animals. Also genetic variation in Theileria species will be determined.

by Muhammad Haseeb Saeed (2008-VA-241) | Prof. Dr. Aneela Zameer Durrani | Dr. Hassan Saleem | Prof. Dr. Azhar Maqbool.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Dogs are most kept and beloved pets in Pakistani society. Dermatophytosis is among the common disease of the pets. Many predisposing factors are involved in development of clinical cases of dermatophytosis including climatic conditions, housing condition of dogs and physical attributes such as coat hair size. Dermatophytosis is not only of concern as being infection of pets but also of its zoonotic importance hence it is very crucial to diagnose dermatophytic infection well in time. Dermatophytosis is caused by Dermatophytes,Microsporum, Trichophyton and Epidermophyton, the fungal species. It is difficult to diagnose the Dermatophytosis from other skin infections by routine tests in most of the cases especially subclinical. Polymerase Chain Reaction (PCR) is advanced and the most reliable technique to detect genome of Dermatophytes even in minute quantities specifically and can efficiently detect the presence of any Dermatophyte specie on the skin of dog. The current study was planned to develop and validate a diagnostic assay which could be able to detect and distinguish tree important dermatophytes species including Microsporum, Trichophyton and Epidermophytonby a uniplex PCR reaction. Analysis of involvement of certain predisposing factors in dermatophytosis was second goal to be worked on in this study. Samples of suspected pet dogs (n=50) were collected by scraping the skin at affected areas over skin. DNA was extracted from the skin scraping samples by organic Phenol Chloroform Isoamyle Alcohol method. Primers, specific to the 18-S ribosomal RNA region of genomes of the Dermatophytes, were designed after alignment of available sequences of Microsporum,Trichophyton and Epidermophyton at NCBI. Annealing temperature and recipe of PCR reaction was optimized by gradient PCR in BIO-Rad thermal cycler. Amplification reaction of all samples collected was carried out as per optimized reaction conditions, afterwards. Amplified products obtained were subjected to genotyping by agarose gel electrophoresis for size based separation of the amplified products. The specific amplified bands of desired genomic region of dermatophytes were seen in UV light transilluminator. The data of results of predisposing factors involved in dermatophytosis wasanalysedby using Pearson’s chi squared test with the help of Statistical Package for the Social Science (SPSS) Program. Genome specific product sizes of Microsporum and Trichophyton i.e. 366 bp and 351 bp in respective positive samples were observed. Out of 50 suspected samples 46 samples were positive for dermatophytosis out of which 38 samples (82.6%) were positive for Microsporum, 6 samples (13%) for Trichophyton and 2 samples (4.4%) were positive for both Microsporumand Trichophyton. This study will help to validate a diagnostic technique for Dermatophytosis with greater efficacy and reliability. Moreover, this investigation may become basis for the future research activities in this field in Pakistan. Availability: Items available for loan: UVAS Library [Call number: 2528-T] (1).

Bat surveys. This is the first extensive exploration of that small portion of the Khyber Pakhtunkhwa which comprises of only three districts of Malakand Division i.e. Malakand, Dir and Swat. Although more focus remained towards Malakand district, six families, fourteen genera, twenty one species were identified. Moreover, two new country Summary 185 records (Myotis formosus and Miniopterus fuliginosis) were also explored. Further bat surveys in poorly surveyed parts of the country especially in KPK and Baluchistan may result in identification of some other new bat taxa. More bat surveys involving greater field efforts may also confirm the presence or absence of those already described from the country. 2. Distribution ranges and species specific habitat analysis. Presence of thirteen new locality records (Pteropus giganteus, Cynopterus sphinx, Rhinopoma hardwickii, Megaderma lyra, Rhinolophus Lepidus, Hipposideros fulvus, Barbastella leucomelas, Scotophilus heathii, Scotophilus kuhlii, Eptesicus serotinus, Pipistrellus javanicus, Pipistrellus dormeri and Scotoecus pallidus) and two new country records (Myotis formosus and Miniopterus fuliginosis) gives credence to the idea that distribution ranges of most of the bat species has change over the past sixty years. Thus serious scientific studies are needed to redefine distribution ranges and identify species specific habitats using global positioning system and radio-telemetric studies. 3. Reconfirmation of bat taxonomy. Genetic analysis of none of the bat species of the country has been made using molecular markers thus leaving behind a chance to doubt identification of cryptic bat species. Thus molecular genetic studies of all the bat species of the country is highly recommended which may also lead to the discovery of such bat taxa which are new to science. 4. Bat call library. The only bat detector (Patterson D 1000X) present in the country fell down from my hand in a water body and became out of order. So none of the bat could be recorded. Bat call analysis has boosted bat identification throughout the world but the Summary 186 lack of such sophisticated equipment in the country has become a major bottle neck in the establishment of a bat call library. 5. Awareness campaigns. Majority of the countrymen are unaware of the ecological services rendered by bats. Khyber Pakhtunkhwa is the major fruit growing region of the country. Based on misperceptions, the locals consider all bats as vermin and kill them ruthlessly. Conservation education to highlight the significance of bats must be included in the curriculum of children at primary school level so that they may adopt a pro-conservation attitude in the first few years of their personality building.

43. Comparative Anthelmintic Efficacy Of Levamisole, Piperazine And Pineapple Leaves Extract(Ananascomosus)Against Ascaridiosis In Captive Java Sparrow (Lonchuraoryzivora)

by Muhammad Zia Ur Rehman Latif (2007-VA-26) | Dr. Syed Saleem Ahmad | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Azhar Maqbool.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Ascaradia galli imposes major health problems on pet birds including the java sparrows. It retards growth, decrease body condition, and lowers the clutch size which imparts huge economic losses to breeders and birds owner. Over dosage of frequently used anthelmintic increase the risk of adverse effects and stress on birds. So there arises a need to adapt alternative therapeutic approaches. The present study was designed to compare the anthelmintic activity of frequently used synthetic drugs levamisole and piperazine and herbal drug pineapple leave extracts against ascariasis in java sparrows.To study the comparative anthelmintic efficacy of levamisole, piperazine and pineapple leave extract against Ascaridia galli in captive java sparrows, fecal sample of (n=200) java sparrows captive for breeding purpose were screened for the Ascaridiagalli by direct fecal smear method. Among the all the infected birds 30 infected and 10 healthy birds were selected to conduct the study and divided into 4 groups and included in therapeutic trial.Birds were treated with levamisole, with piperazine and with pineapple leaves extract according to standard dose rate and route of administration in Group A, B & C respectively, Fourth group D comprising of 10 birds waskept as negative control. To evaluate the comparative efficacy of drugs, EPG will be calculated according to McMaster Technique post treatment at day 0 and after treatment on 7th, 14th and 21s. Results revealed that levimosle was the very effective against Ascaradia galli in java sparrows. Levaimsole decrease the average EPG of treated group to 50 from 600 and show 100 percent efficacy against Ascaradia galli and recovered all the infected birds of the group A. Piperazine was less effective as compare to the levamisole but show more effectiveness as compare to the pineapple leave extract. Piperazine reduced the average EPG of treated group B to 150 from 650 and show 70 percent and recovered 7 infected from 10. Pineapple leave extract showed least effectiveness and reduced the EPG of treated group C to 350. Pineapple showed 40 percent efficacy against Ascaradia galli and recovered only 4 infected birds of group C from Ascariasis.Pineapple leaves extract were effective against ascariasis in captive Java sparrows but least effective as compare to levamisole and piperazine having no adverse effects.
