Publisher: 2005Dissertation note: The present project has been designed for identification and chemotherapy of
ecto-parasites of camels (Camelus dromedarius) from different areas of Dera-Ghazi-Khan. For this purpose 300 camels were examined during the period October to November 2004. Out of 300 camels 109(36.3%) were found infested with ecto-parasites. Two types of ectoparasites were found to be active during those days. Sixty three camels were infested with ticks. After collection these ticks were mounted for identification, with the help of their morphological characters. The only tick found to be identified was Hyalomma dromedarii and the tick infestation was found to be 21% in those areas during October-November 2004.
Similarly, 85 suspected camels were examined by skin scraping in the District Veterinary Diagnostic Laboratory, Dera-Ghazi-Khan, for identification of mites 46 camels weie found to be infested with mange mites and the mange mites infestation was 15.3%. The species of mites identified was Sarcoptes scabiei var. cameli.
For chemotherapeutic trails 60 positive ecto-parasitic camels were divided into 3 groups i.e. A, B and C, 20 camels in each group. For further procedures these groups were divided into sub-groups i.e. A (Al + A2), B (Bi + B2) and C (Cl + C2) where each sub-group contained 10 animals (camels). Al, Bi and Cl were infested with mites and A2, B2 and C2 with ticks. The group A was treated with Ivermectin (Baymec; Bayer) at dose rate of 1 m1150 kg body weight sub/cut. Similarly the group B was treated with Neguvon (0.15%) solution with spray machine. Where the group C acted as infected, non-medicated control group.
The efficacy of Baymec on 7th day was 75% and on 14th day was 80%. But the efficacy of Neguvon (0.15% solution) on 7th day was 65% and on 14th day was 75%. The camels of group C were not treated and acted as control.

Publisher: 2005Dissertation note: Keeping in view the zoonotic importance of Toxoplasmosis the present study was carried out to determine the seroprevalence of Toxoplasma gondii infection in sheep and goats using commercially available kit "Toxopalasmosis Latex" based on the principal of Latex agglutination. . For this purpose 100 blood samples (50 sheep & 50 goats) were collected randomly from slaughter house of Lahore and local sheep & goat forms, the serum was separated and analyzed for anti Toxoplasma antibodies. The animals were divided in three groups, Group I included animals below one year, Group II 1-4 years and Group III included animals aged 4 years and above. The overall 8% and 6% seroprevalence were recorded in sheep and goats respectively. Age titer relationship in sheep showed that Group III had (12.5%), Group 11(7.6 %) and Group I had no positive cases in sheep examined. In goats Group III had (10 %), Group II (5.7%) and no seropositive cases in Group I could be recorded. These results indicate that the infection was higher in older animal than young ones, Breed wise seroprevalence indicated that, Kchhi sheep 14.28%, Desi (non descript) 8.33% and no seropositive case in Lohi and Thali breeds was recorded. In goats Teddy breed had 11.11%, Desi (non descript) 5.55% while no seropositive case in Beetal goats could be recorded.
From the data analyzed it is concluded that although the seroprevalence of T gondii infection in sheep and goats is relatively low in this area as compared to the other parts of the world. Yet adequate management might be useful and essential to further minimize the infection in sheep and goats herds. Consequently, preventive measures could further reduce the exposure of toxoplasmosis in the human population.

Publisher: 2005Dissertation note: A study was conducted to determine the prevalence of various enteric protozoan infections in sheep. A total of 225 fresh faecal samples were collected from different sheep farms in District Swat N.W.F.P. These animals belonged to three different age groups i.e. Group I (up to 6 months of age), Group II (7-12 months of age) and Group III (above 1 year of age). Faecal samples were processed for the detection of Eimeria spp. oocysts, Giardia cysts, Cryptosporidium oocysts and other parasites by three different techniques. By Direct smear method, Sheather,s sugar flotation and zinc sulphate flotation technique. A total of faecal samples found positive for Eimeria oocysts 63 (28%), Giardia cysts 35 (15.55%), Cryptosporidium oocysts 16 (7.11%) and mixed parasitic infection 58 (25.77%). Data recorded for various protozoan infections indicated that prevalence rate in Group-I (Eimeria 37.33%, Giardia 22.66% and Cryptosporidium 12%) was higher than the Group-II (Eimeria 28%, Giardia 16% and Cryptosporidium 3%) and Group-III ( Eimeria 18.66%, Giardia 8% and Cryptosporidium 5.33%). Prevalence rate was also higher in diarrhoeic animals (Eimeria 35.71%, Giardia 23.80% and Cryptosporidium 16.66%) than the non diarrhoeic animals (Eimeria 26.22%, Giardia 13.66% and cryptosporidium 4.91%). A large number of faecal samples (25.77%) were found positive for various other parasitic infections. No significant difference was noted in males and females. Results of this study indicated wide spread prevalence of parasitic diseases in sheep population and mostly young animals were found to be infected by different protozoan parasites.
It can be concluded that enteric protozoan infections in sheep can be controlled through improved managemental practices, hygienic measures and avoidance of overcrowding the animals.

; Nature of contents: ; Literary form: Publisher: 2005Dissertation note: Gigantocotyle explanaturn is one of the most prevalent paramphistome among the flukes which parasitize cattle and buffaloes. Diagnosis of parasitic diseases can be performed by coprological and immunological techniques. In the present study standardization of agar gel diffusion test (AGDT) was carried out. The soluble antigen of Gigantoco1'/e explaflatuni was prepared after homogenization of adult flukes in normi' saline and subsequent collection of supernatant after cenirifugation. 1-lyperimmunc senim against the antigen was rflise(l in rabbits. Agar gel plates were prepared and antigen was standardized against known positive serum. The faecal and blood samples were collected from 200 suspected buffaloes from two abattoirs of the Lahore city. AGDT was performed for serological identification of the samples and coprological examination for detection of ova. The recovery of flukes from the liver, bile duct and gall bladder of thc same animals was also carried out. 'l'he efficacy of serological and coprological examination for the diagnosis of G. explanatum was compared with that of direct recovery of parasite from liver of slaughtered animals.
Out of the 200 buffaloes 51 (25.5 percent) harhoured (7, explanatum in their livers, bile duct and gall bladder. The serological examination of the same animals showed that antibodies against (7. explanalum were detectable in 29 (56.85 percent) buffaloes by AGDT while the coprological examination of same animals revealed that ova of (i. explanatum were present in 23 (45.1 percent) out of the 51 animals. From these findings it can be inferred that efficacy of AGDT is superior to faecal examination and could become a useful technique for herd diagnosis of G. explandatum in buffaloes under field conditions.

Publisher: 2006Dissertation note: To final out the comparative efficacy of different control measures against Argas persicus, In-Vitro and In-Vivo studies were carried out for the in-Vitro studies three thousand soft ticks Argas Persicus at different stages of their development were used in the experiment. The ticks were divided in to 5 groups A, B, C, D and E having 600 ticks in each group. The ticks of each group (600) were further divided in to three replicates having 200 ticks in each. The ticks were maintained in small plastic boxes containing tick rearing medium at a controlled temperature of 25 Co and 60% relative humidity. The 5 treatments are applied with a small (1 liter) hand held sprayer at the rate of 20ml per box 345 cm2 surface area. The first application was made after 24 hours and repeated twice at 48 hours intervals. On day 0,3,5,7 and 10, the ticks were separated from the manure by immersing the manure in water and retrieved the ticks with the help of sieve. The ticks relating to each group were counted and the counts of each group were compared. The reduction in the counts in test groups as compared to control group A indicated the efficacy of the treatment. It was noticed by the comparative mortality of the ticks in the replicates of different groups that in mortality of ticks in Group A occurred as 6.17% in B as 67.67% in C as 70.67% , in D as 100% and in E as 71.83%. The findings of the In Vitro experiment showed that the efficacy of Tiekide was 100% and in ranking order was placed at No. 1 amongst the test groups and the difference was statistically significant (P<0.05) as compared to B, C and E groups. However the findings of Groups B, C and E were not significant amongst each other (P>0.05). For the In-Vivo studies, the experiment was conducted on a layer farm infested with Argus persicus. A total of 100 layers infested with Argas persicus were reared under experimental conditions on particular farm. One hundred infested birds were divided into 5 groups i.e A,B,C,D and E, each group consisting of 20 birds. The ticks of all members of the groups were counted on day 0,3,5,7 and 10. Group A acted as infested and non treated, B was treated by application of EM1 under the infested wings, C was applied EM5, D was applied Tiekide (Homoeopathic formula) under the wings the medicine was also orally administered @ 2 drops in 1 ml water and members of Group E were applied 1% solution of Ivomec (Ivermectin). The results indicated that the reduction in the mean tick counts was 95.74% in Group D which was placed at No. I, in descending order the mean tick counts reduced by 70.97% in Group E, 68.59% in Group C, 67.63% in Group B and only 1.93% in control Group A. The Tiekide was claimed to be a drug of choice.

Publisher: 2006Dissertation note: It is an established fact that parasitic diseases are one of the principal obstacles in the health of animals. Some of these parasites survive at the expense of the blood of animals, thus causing irritation, anemia and consequently leading to weakness and debility. Some of the parasites are zoonotic in nature and may be a cause of contagious disease like Scabies to human beings by direct contact (Dominguez et al., 1978).
Canine scabies is an extremely pruritic and contagious skin condition caused by epidermal mite, Sarcoptes scabies var canis (Prescott, 1970). The disease spreads from dog to dog by direct contact., Clinical signs include intense pruritis, erythema, papular eruptions, accumulation of keratotic tissue and alopecia of the affected areas. Severely affected dogs may have open lesions caused by scratching. Scabies lesions are mostly seen in the muzzle, chest, elbow, around the eyes and in the ears and then spread to back and abdomen.
Dogs are kept as pet by quite a number of people in Pakistan.People became infected in about 50% of canine cases. however, the dermatosis in people usually dissipates spontaneously 2-4 weeks after the animal is treated (Folz et at., 1984) In the present study a total 620 dogs of various breeds and of both sex were examined for the presence of Sarcoptes scabiei var canis.OF these seventy five (12.9%) were found positive,of these dogs 50 were selected for therapeutic trials.these were randomly divided into five groups i.e.A, B, C, D & E having ten dogs in each group.these dogs were treated with Ivermectin,Cypermethrin,Nicotiana tobaccum & Azadirachta indica. Efficacy of the drug was calculated on the basis of disappearance of signs,negative skin scraping and subsidence of the skin surface..the result showed that Ivermectin was 100%on 28th day of treatment,followed by Cypermethrin 90%, Nicotiana tobaccum70% ,where as the lowest efficacy showed by Azadirachta indica i.e.60

Publisher: 2006Dissertation note: To find out the therapeutic and prophylactic efficacy of toltrazuril against coccidiosis, an experiment was conducted in the Department of Parasitology, University of Veterinary & Animal Sciences, Lahore.
One hundred and sixty (160) day old chicks were divided into 8 groups, i-e, A, B, C, D, E, F, G and H each consisting of 20 chicks. Group A acted as non-infected and non-medicated control, B was infected with Eimeria tenella sporulated oocysts on day 16 and 26 @ 20000 per chick and acted as infected control. Similarly, all other members of different groups were also infected at the same rate. Members of Group C were administered toltrazuril orally in drinking water @ 7 mg/ kg body weight on day 18 & 19 and 25 & 26. Members of Group D were given toltrazuril @ 3.5 mg/kg body weight, of Group E @ 1.75 mg/kg as in group C & D, of Group F toltrazuril was given as prophylactic @ 7mg/kg on day 3 & 10. Members of Groups G & H were given irradiated (IEV) and formalized (FEV-48) Eimeria tenella vaccines respectively. IEV was orally given on day 3 & 10 whereas FEV was only given on day 10 of age.
The result indicated that maximum reduction of OPG counts (94.28 %) occurred in members of group D which was given half the dose (3.5 mg/kg) of toltrazuril, Group E (Administered quarter dose) was placed at no.2 and the reduction in this Group occurred as 93.71 %. The group G (IEV immunized) was placed at no. 3 by reducing 89.71 % mean OPG counts as compared to control Group B.
In terms of reduction of OPG counts other Groups were placed at no.4 (Group F given full dose prophylactic), no.5 (Group H immunized with FEV-48) and Group C showed the poorest performance (63.42 %) which was given full dose was placed at no. 6.
In terms of Mean body weight gains as compared to control (healthy) Group A, Group D was placed at no.1, Group E at no.2, Group G at no.3, Group C at no. 4 Group F at no.5, Group H at no.6 and Group B which acted as infected and non-medicated was placed at no.7. Ultimately, it was concluded that toltrazuril @ 3.50 mg/kg or immunization with IEV (irradiated vaccine) would be the best solution to the coccidiosis problem

Publisher: 2006Dissertation note: Food borne trematode infections have been recently identified as an important public health problem having considerable economic impact in terms of morbidity, loss of productivity and health care costs. Fish serve as second intermediate host of food borne trematode infections and serve as direct source of infection in humans. In the present study four different species of fish i.e. Labeo rohita (rohu), Cirrhnuh mrigala (mori thela), Catla catla (thela) and Hypophteamicty thyesmolitris (silver carp) serving as intermediate hosts of food borne trematodes were identified and also recorded the prevalence and intensity of infection due to metacercariae of food borne trematodes in common food fishes of Pakistan. For this purpose 222 different samples of fish were collected from numerous water bodies i.e. Rawal Dam, Islamabad and Mangla Dam, and local fish markets and detection of infection metacercariae of opisthorchis/clonorchis and heterophyids by pepsin digestion technique. Overall infection rate was 28.37 percent species wise prevalence indicated that catla catla and Labeo rohita were more frequently affected than other so whereas the lowest (23.5%) prevalence was reported in Hypophteamicty thyesmolitris. As the people of Pakistan are not consuming raw or undercooked fishes so prevalence of zoonotic diseases transmitted from fish are not recorded in Pakistan. However, experiment conducted on mice indicated that when metacercarial infection was given to mice, adult worms were isolated from the mice.

Publisher: 2007Dissertation note: Hydatidosis is caused by metacestode of the dog worm Echinococcus granulosus. It is a serious problem for both Public health and livestock economy.Echinococcus granulosus has number of genetically distinct strains which are known to differ morphologically and epidemiologically. Out of 1000 sheep and goat examined only 45 Samples of hydatid cysts were collected from different organs i.e. livers, kidneys, lungs and hearts from Lahore abbatoir. Fertility and viability of the cysts was observed microscopically. Genotyping of Echinococcus granulosus was performed through Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP). Seroprevalence of hydatidosis in 50 butchers working in abattoir was also determined by the use of Latex agglutination test (LAT) kit for detection of hydatidosis.
Considerable information is available about genetic variants of E. granulosus around the world. Ten genotypes of E. granulosus have been described, which exhibit a diversity of morphology, development, and host range, as confirmed by various studies. In the Mediterranean area, the Gl or common sheep strain, 02, the buffalo strain 03, and the equine strain 04 have been found in Spain, Italy, Lebanon, and Syria
To date, molecular studies using mainly DNA sequences cytochrome oxidase subunit 1 (COl) and NADH dehydrogenase 1 (ND1) genes have identified ten distinct genotypes (01 -G 10) within E. granulosus. This categorization follows very closely the patterns of strain variation emerging from biological and epidemiological traits.
In this study we perform serum analysis of butchers to detect antibodies against Echinococcus so that the prevalence of Echinococus can be checked, the data available indicated that 14% of butchers population is infected with Echinococus. In order to confirm the starin of Echinococcus in sheep and goat the PCR-RFLP analysis of ND I gene of Echinococus were performed .The data obtained was analysed and it was concluded that the 01 strain of echinococus is prevalent in sheep and goat in Punjab area. It is hoped that the findings of the present study will be helpful for further planning about the control of the disease and correlating the prevalence in sheep, goats and butchers from the zoonotic point of view.
The results demonstrated that PCR-RFLP analysis of samples of patients suspected for Echinococcus is a promising diagnostic method and also confirms the type of Echinococus prevalent in that area and also enables an early direct detection of parasite DNA. This will help to curtail this drastic malady at an early stage and will help to devise the trategy to minimize the losses due to this disease.

Publisher: 2007Dissertation note: In present study a total of 100 serum samples from indigenous poultry and the dressers were analysed for determination of Toxoplasma specific anti-bodies. Under aseptic measures 1-2m1 of blood was withdrawn by veinpuncture and serum was separated. All the serum samples were analyzed for specific IgG anti Toxoplasma ant-bodies using Latex Agglutination Test (LAT). Positive reaction was visualized by the naked eyes or magnifying hand lens.
Commercially available Toxoplasma Latex test kit was used to determine the serum antibodies. Results were interpretated, data obtained was analyzed statistically by calculating the percent sero-positivity of Toxoplasma gondii in indigenous poultry.
Toxoplasma is one of the most common zoonosis worldwide.It is caused by toxoplasma gondii, an obligatory intracellular parasite that attacks warm blooded animals,birds including humanbiengs.Felines are the definite hosts where the parasite carries out its sexual cycle resulting in oocysts that are taken to the environment by the feces.Man birds and animals acquire the infection by ingesting oocysts that contaminate water,foodstuff, and pasture in that environment.
In the present study the overall seroprevalance of toxoplasma gondii infection in indigenous poultry and dressers are 12% respectively by using Latex agglutination test.
In indigenous poultry seroprevalance of toxoplasma gondii was 10% out of 100 hens examined, (3) were seropositive at screening dilution of 1:256 suggesting possible recent contact.
(2) were seropositive at 1:128 which was due to acquired or evolving immunity, while (1) were seropositive at screening dilution at 1:16 indicating residual or non specific immunity.
Toxoplasma gondii infection is increased with age because of constant exposure to contaminated environment and increased contact with cats.
In dressers (butchers) seroprevalance was 12% out of 50.Two were seropositive at screening dilution of 1:256 suggesting possible recent contacting.Two were seropositive at 1:128 which was due to acquired or evolving immunity,whike two were seropositve at screening dilution at 1:16 indicating residual or non specific immunity.
Due to increase prevalence of toxoplasmosis in humans,birds and animals daby day it is very necessary that public should be aware about the zoonotic importance of this disease and preventive measures to be adopted.

Publisher: 2007Dissertation note: Amoebic dysentery (amoebiasis) is an infection of the intestine (gut) caused by a unicellular organism called Entamoeba histolytica, which, among other things, can cause colic, intestinal ulcers and abscess on vital organs of body. Amoebae are parasites that are found in contaminated food or drink. They enter the body through the mouth when the contaminated food or drink is swallowed. The amoebae are then able to move through the digestive system and take up residence in the intestine and cause an infection. They can also move to other organs of body like liver, lungs etc by extra luminal penetration. They make cysts in the intestine as well as on the effected body organs. These cysts are passed along with feces. In the course of research, a total 100 fecal and 100 blood samples of dogs and their owners were collected from two hospitals i.e. Pet Centre and Lahore Animal Hospital for detection of Entamoeba histolytica. These causative organism was examined in the feces by direct fecal method as well as by flotation method while in case of extra luminal invasion their antibody level were checked by the latex agglutination test both in dogs as well as in their owners.
In the present study the overall prevalence of Entamoeba histolytica in dogs and their owners was 13% and 10% respectively by using Latex agglutination method for serum samples and direct and flotation method for fecal samples. Due to its high prevalence of amoebiasis in humans and pets it is the need of hour that general awareness comping towards zoonotic diseases for public must be provided to cope with amoebiasis and other zoonotic diseases.

Publisher: 2007Dissertation note: The effects of oral administration of Sugar Cane Extract (SCE) on Elmeria tenella oocysts infection in commercial broiler chickens were evaluated in this study. For the purpose an experiment was conducted in the Department of Parasitology, University of Veterinary & Animal Sciences, Lahore.
One hundred and sixty (160) day old chicks were divided into 4 groups, i.e. A, B, C and D each consisting of 40 chicks. Group A acted as non-infected and non-medicated control (healthy control), group B was infected with Elmeria tenella sporulated oocysts on day 21 @ 20000 per chick and acted as infected control. Members of Group C were orally administered SCE @ 500mg! kg body weight on day 21 and then challenged with the same dose of E. tenella oocysts. Members of Group D were orally administered SCE at the dose rate of 500mg/kg body weight for three consecutive days and then challenged with the same dose of E. tenella oocysts. The result indicated that maximum reduction of OPG counts (98.73%) occurred in members of group D which were administered SCE (500 mg/kg) for three consecutive days and then challenged with E. tenella oocysts. Group C (Administered SCE for a single day @ 500mg/kg) was placed at no.2 and the reduction in this Group occurred as 83.54% as compared to Group B. Mean body weight gains were calculated by taking difference between average weight records on day 21 & day 35 of age (final weight record). The difference of each group was compared with healthy control and percentage of weight gains of all the groups were recorded and also compared as in table 6. Therefore in terms of Mean body weight gains as compared to control (healthy) Group A, Group D was placed at no.1, Group C at no.2 and Group B which acted as infected and non-medicated was placed at no.3 in terms of body weight gains. These results suggest that SCE have immunostimulating and protective effects against E. tenella infection in broilers.

Publisher: 2008Dissertation note: Hydaiidosis is caused by metacestode of the dog worm Echinococcus granulosus. It is a serious problem br both Public health and livestock economy. Echinococcus granaiiosu.s has number of genetically distinct strains which are known to differ morphologically and epidemiologically. Out of 100 camels examined only 25 Samples of hydatid cysts were collected from different organs i.e. livers, kidneys, lungs and hearts from Lahore abattoirs. Fertility and viability of the cysts was observed microscopically. Genotyp ing of Echinococcus granulosus was performed through Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP). Seroprevalence of hydatidosis in 25 butchers working in abattoir was also determined by the use of Latex agglutination test (LAT) kit for detection ob hydatidosis.
Considerable information is available about genetic variants of E. granulosus around the world. Ten genotypes of E. granulosus have been described, which exhibit a diversity of morphology, development, and host range, as contrmed by various studies. In the Mediterranean area, the CI or common sheep strain, G2, Camel strain G6, and the equine strain G4 have been found in Spain, Italy, Lebanon, and Syria
To date, molecular studies using mainly DNA sequences have identitied G-6 strain of E. granulosus. This categorization follows very closely the patterns of strain variation emerging from biological and epiderniological traits.
In this study we perform serum analysis of butchers to detect antibodies against Echinococcus so that the prevalence of Echinococcus can be checked; the data available indicated that 14% of butcher's population is infected with Echinococcus. In order to confirm the strain of Echinococcus in camels the PCR-RFLP analysis were performed. The data obtained was analysed and it was concluded that the G6 strain of Echinococciis is prevalent in camels in Pakistan. The results demonstrated that PCRRFLP analysis of samples of patients suspected for Echinococcus is a promising diagnostic method and also confirms the type of Echinococcus prevalent in that area and also enables an early direct detection of parasite DNA. This will help to curtail this drastic malady at an early stage and will help to devise the strategy to minimize the losses due to this disease.
It is hoped that the findings of the present study will be helpful for further planning about the control of the disease and correlating the prevalence in camels and butchers from the zoonotic point of view.

Publisher: 2008Dissertation note: To record the prevalence of soil borne helminthiasis of zoonotic importance in dogs' one hundred faecal samples were obtained from pet dogs, fifty from pups of age less than six months and fifty from adult dogs. Four hundred soil samples along with grass were also be collected from different dog kennels, parks and playgrounds, backyards and streets of Lahore city, where soil and grass is contaminated with the faeces of stray dogs. After collection, the faecal samples were preserved in polythene bags and kept in refrigerator or preserved in 10 % formalin to avoid any other contamination of the samples. Then the samples were brought to the Diagnostic Laboratory, Department of Parasitology University of Veterinary & Animals Sciences, Lahore. Microscopic examination was performed by using different parasitological techniques like Direct Smear Method, Floatation Method and Sedimentation Method for the detection of the parasite ova. Grass Samples were examined through Sedimentation-Flotation Method. The results were analyzed by using chi2 test to check the significance difference of the ova in soil samples of different areas. the result showed that out of 400 soil and grass samples 33 were positive for Ancylostoma caninum, 37 were positive for Toxocara canis, 29 were positive for Dipylidium caninum and 19 were positive for Echinococcus granulosis and out of 100 faecal samples taken from pups and adult dogs, 10 were positive for Ancylo stoma caninum, 13 were positive for Toxocara canis, 8 were positive for Diplyidium caninum and 6 were positive for Echinococcus granulosis. The results suggested that better deworming stragies shold be adopted so that the health of the dogs can be improved and this will also reduce the reisk of zoonotic infectin in humans, entry of the stray dogs in public areas should be restricted to avoid the risk of zoonotic diseases.

Publisher: 2008Dissertation note: Ciyptosporidiosis is caused by oocysts present in water or faeces. It is a serious problem for both Public health and livestock economy. Ciyptosporidium has four species i.e., C. parvum, C. muris, C. wrairi, and C. felis in which Cryptosporidium parvum is most important as it is the more prevalent species.
Out of 300 animals examined only 90 animals were showing diarrhoea. For the detection of Ciyptosporidiosis the faecal samples were examined by ZN staining under light microscope. Out of three hundred calves samples only sixty were found positive for Cryptosporidium oocysts while rest of two hundred and forty were found negative.
Four thousand oocysts per gram of faeces detected by ZN staining are considered positive of ciyptosporidiosis. In this study only forty six samples showed threshold number of oocysts per gram of faeces while eleven were positive but their count was less than four thousand per gram. There were three such samples which show very few numbers of oocysts per gram of faeces.
Samples from female calves showed more positive results as compared to samples from male calves. There was also an interesting fact that the age group ranging from, day eleven to day twenty one, were showing more positive samples as compared to the age group ranging from, day one to tenth day. The overall percentage of positive samples was twenty percent.

Publisher: 2009Dissertation note: The most important allergy causing mites found worldwide in houses are the house dust mite's i.e. D. farinae & D. pteronyssinus and most houses contain multiple species. The geographical distributions of mite species are vary between houses within a geographical region and among different areas. Therefore it is need to know the exact prevalence of species in a particular area when diagnostic testing is performing and prescribing immunotherapy. Among environmental factors, temperature and humidity play a key role for the survival as well as prevalence of house dust mites. The most favorite place for the better survival of house dust mites is houses belong to the humid geographical areas.
In this study, 1280 dust samples from carpet, bedroom mattress, sofa and floor of total 64 houses from posh area and old city area from May to August, 2007, were collected and two examination procedures were selected (Acarex Strips Test and Direct Microscopic Examination). 320 dust samples (160 posh area and 160 old city area) were detected with Acarex Strips Test and remaining dust samples were examined by using the direct microscopy.
In the present study, the overall occurrence of house dust mites in dust samples of carpet, bedroom mattress, sofa and floor was recorded as 22.5% (9), 22.5% (9), 20% (8) and 10% (4) respectively from posh area by using the Acarex strips test from May to August, 2007, at Lahore. Similarly from old city area, the overall occurrence of dust mites from house dust samples of carpet, bedroom mattress, sofa and floor was reported as 27.5% (11), 30% (12), 22.5% (9) and 15% (6) respectively.
Direct microscopy was performed for remaining 960 (240 carpet, 240 bedroom mattress, 240 sofa and 240 floor) dust samples to examine the occurrence and taxonomy of house dust mites. Among 26.3% (63) positive dust samples of carpet 63.5% (40) were found positive for D. farinae and 36.5% (23) for D. pteronyssinus. Total 28.8% (69) bedroom mattress dust samples were found positive for house dust mites but 74.9% (51) and 26%
(18) dust samples were containing D. farinae and D. pteronyssinus species respectively.
Among 17% (41) positive dust samples of sofa, 61% (25) were containing 13. farinae and
39% (16) D. pteronyssinus. Out of 11.7% (28) positive dust samples of floor for house dust mites, 68% (19) were examined positive for D. farinae and 32% (9) for D. pteronyssinus.
The high occurrence of house dust mites were seen during May, June, July, and August 2007. During May, 2007, there was not so highly occurrence of house dust mites observed as compare to other three months (June, July and August, 2007). From late June rainy season (monsoon) was started and high moisture remains in the environment to late August. These environmental conditions have direct impact on the population of house dust mites.
From previous study, it was suggested that two species (D. farinae and D. pteronyssinus) occur in the area of Lahore, Pakistan. The highly prevalent specie in the house dust samples of carpet, bedroom mattress, sofa and floor was reported D. farinae as compare to D. pteronyssinus.

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.

A total 240 gastrointestinal tracts of sheep from district Zhob abattoir were collected. These samples were isolated and identified for trichostrongylid nematodes. The overall prevalence was 50%(120/240), of which 39.1% in male and 60.8% in female sheep were recorded at slaughter-house. Plants were collected from area of district Zhob. These plants were Identified and authenticated by botanist .The crude aqueous methanolic extract of the plants were used for in-vivo studies. Eighty sheep of either sex, aged between three to six months and naturally infested with Trichostrongylid nematodes (including trichostrongylius spp. I-Iaemonchus contortus, cooperia etc) were selected and managed separately for the experiment. These sheep were divided into 4 groups A ,B,C and D. Group A was contained 10 sheep and was untreated and considered as control. Thirty (30) were kept in Group B, were further sub divided into three equal groups i.e. BI, B2 and B3 and treated with different levels of Chenopodium album @ 1, 2 and 3 g/kg body weight respectively. Group C having thirty (30) was also sub divided into three equal groups i.e. Cl, C2 and C3 and treated with different levels of Artemisia brevifolia @ 1, 2 and 3g/kg body weight respectively. Group D was treated with Levamisole @ 7.5 mg/kg body weight. Faecal egg count reduction was criterion for evaluation. Faecal samples were collected before treatment on day 0 and on day 3, 5, 7, 10 and 14 post treatments for EPG count.
The results of EPG for animals in group B1 at day 0 was 1325. This rate was reduced to 1250, 1125, 995 and 702 at day 3, 7, 10 and 14, respectively. Similarly EPG of sheep in B2 were 1280 at day 0 and reduced to 1205, 1202, 1001 and finally to 690 at day 3, 7, 10 and 14 respectively. Best results in B group against the nematodes were in B3 in which Chenopodium album was used 3g/kg bw. The results were 1250, 1231, 1145, 590 EPG at day 0, 3, 7, 10 and 14. The sheep in group Cl showed 1203 EPG at day 0, when treated with Ig/kg bwArtemisia brevifolia, the EPG was reduced to 1173, 1115, 700 and 528 on day 3, 7, 10 and 14 respectively. Second level of treatment C2 of
Artemisia brevifolia which was given @ 2g/kg bw initially contained reduced to 1202 EPG, on day 3, 7, 10 and 14 the EPG counts were 1020, 631, 546 and 459, respectively.
Highest dose of Artemisia brevfolia was 3g/kg body weight to sheep in group C3. On day zero the EPG count was 1196. On day 3, 7, 10 and 14th day the EPG count decreased to 1079, 905, 528 and 396 respectively. The sheep in group D, treated with recommended dose of Levamisole showed 1138 EPG prior to medication, which reduced remarkably to 681, 536, 357 and 147 on day 3, 7, 10 and 14 respectively. Although no untoward effects of plants were observed but best EPG reduction results (87.08 %) were observed in Levamisole as compared to treatment of 3gm/kg b.w Chenopodium album (51 .03 %) and Artemisia hrevfolia 3g/kgbw (66.88 %).
CONCLUSIONS
A wide variety of plants are naturally available in the Indo-Pakistan subcontinent which possess narrow or broad spectrum anthelmintic activities. No doubt this is true in other regions of the world as well where gastrointestinal parasitism is an important problem in livestock keeping, and the availability of commercial drugs may be limited. Conventionally, trichostrongylids has been tackled with use of synthetic anthelmintic but owning to development of anthelmintic resistance against major groups of anthelmintics viz., benzimidazole, Levamisole and avermectins, people are looking for alternatives to synthetic chemicals.
The phytochemical analysis of these plants and controlled anthelmintic trials along with contemporary knowledge of parasite control strategies may offer new opportunities for effective and economical control of parasitic diseases. So these plants can be better alternative for synthetic chemicals.
Quality control extracts of Artemisia brevifolia and Chenopodium album or possibly isolated bioactive compounds could be a promising alternative to conventional anthelmintics fbr the treatment of gastrointestinal trichostrongylids of small ruminants in the future. Such a treatment could be used in control strategies against gastro intestinal nernatodes in organic and conventional production systems. Further research is needed for studies on the bio active constituents, as well as on the reproducibility, dosage, application regime. toxicity and effectiveness of Artemisia brevifolia and C'henopodium a/bums in other host species and against other economically important gastro intestinal nematodes species.
RECOMMENDATIONS
It is recommended that further research could be carried out on large sample size in different seasons of the year and large number of plants, identification of active principles of plants with proven anthelmintic activity, standardization of dose and toxicity studies for drug development. In addition to this, large number of samples of the same plant from different geographic areas should be subjected to experimentation keeping in view the possibility of differences in chemical composition of soils.

Publisher: 2010Dissertation note: External parasites like ticks causes great economic losses in poultry in term of low productivity, anemia, and secondary bacterial infection. Keeping in view economical importance of this problem the project was designed to record the prevalence of Argas persicus in poultry and to treat the birds with different drugs. For this purpose indigenous poultry at Lahore was visited for the collection. Overall prevalence of tick infestation and
identification of ticks was on the basis of their taxonomic characteristics. During the study period 5207 ticks were collected from five hundred birds. Three species of Argas were identified, 3316 were belonging to Argas Persicus (65.02%), 935 Argas reflexus (17.95%), (18.32%), 957 were Argas vespertilionis. Antigen was prepared from the mouth parts of ticks. Five hundred blood samples were taken from birds found positive. Sera were centerifuged and subjected to AGID test. Overall 19.4% prevalence of Argas persicus was recorded. Age -wise 8.19% and 25.8% prevalence was observed in chicks and adults respectively. The highest prevalence during spring was (26.8%) due to high humidity reason. One hundred layers were selected for therapeutic trials. These were randomly divided into 5 groups i.e., A, B, C, D and E. Birds in group A, B, C, D was treated with Cypermethrin, Ivermectin, Permethrin, and Dormectin respectively. Where as birds in group E was served as untreated control. Efficacy of drugs was calculated on the basis of reduction of ticks on the body of poultry. The efficacy of drug trial was noted in poultry subunits for a period of 15 days. The maximum control was achieved by Cypermethrin (90.7%), Ivermectin (90.35%), Dormectin (89.3%) and Permethrin (88.9%).
The data were analyzed statistically by using NPar test, kruskal-Wallis test and Median test (Steel and Torrie 1989).

Publisher: 2009Dissertation note: Coccidiosis is the major parasitic disease of poultry and is caused by the apicomplexan parasites Eimeria. Drugs and live vaccines are the two main control measures of the disease; however, due to increasing concerns with prophylactic drug use and the high cost of vaccines, alternative control methods are needed. Recent evidence that various dietary and live microbial supplements can influence host immunity against enteric diseases prompted me to investigate the role of prebiotic, probiotic on coccidiosis in broiler chickens. Neem fruit (azadirachta indica) and diclazuril is also used in the experimental trial due to their anticoccidial activity. For this purpose a total of 300 day old chicks free from coccidial infection were randomly divided into six groups (A, B, C, D, E and F) each comprising 50 birds. The dietary treatments for groups A-F were basal diet only, basal diet + Diclazuril 0.5%, basal diet + lactobacillus based probiotic, basal diet + Mannan-oligosacchrides (MOS), basal diet + neem fruit (Azadirachta indica) and basal diet only, respectively. The birds in groups A-E were challenged oesophageally with 10000 viable sporulated E. tenella oocysts, while the birds in group F were remained unchallenged and serve as negative control. The oocyst per gram (OPG), clinical signs/severity of diarrhea, lesion score, body weight gain, feed consumption, FCR, mortality rates, hemoglobin estimation, total leukocyte count and differential leukocyte count were the parameters considered. The efficacy of various treatments was estimated on the basis of reduction in OPG, clinical signs/severity of diarrhea and lesion score. The effect of coccidiosis on hemoglobin, total leukocyte count and differential leukocyte count were also recorded. The data thus obtained were subjected to statistical analysis using Analysis of Variance (ANOVA) Technique. The difference among the treatment means were tested by Duncans's Multiple Range (DMR) Test.
The results of the experiment revealed that oocyst per gram (OPG), clinical signs/severity of diarrhea, lesion score, mortality rates, feed consumption, hemoglobin estimation, total leukocyte count and differential leukocyte count of group D and C were significantly lower than group A, B and E (p<O.O5) respectively except group F (-ye control), but feed consumption of group C and D is significantly lower than group F (p<O.05). Body weight gain, and FCR of group C and D were significantly higher than group F, followed by E, B and A (p<O.O5) respectively.
From the results of above experiment it is concluded that both prebiotic and probiotic not only facilitate as an anticoccidial but also helpful in body weight gain. These consequently result as an alternative drug free approach to antibiotics for the control of coccidiosis because of drug resistance as well as growth promoter and ultimately reduce the economic losses due to coccidiosis.

; Nature of contents: ; Literary form: Publisher: 2008Dissertation note: ACystic echinococcosis (CE) is the larval cystic stage (called echinococcal cysts) of a small taeniid-type tapeworm (Echinococcus granulosus) that may cause illness in intermediate hosts, generally herbivorous animals and people who are infected accidentally. Echinococcus granulosus has number of genetically distinct strains which are known to differ morphologically and epiderniologically. Out of 150 cattle and 150 buffalo examined only 42 Samples of hydatid cysts were collected from different organs i.e. livers, kidneys, lungs and hearts from Lahore abbatoir. From 42 positive samples, 25 cysts were found in cattle and 17 cysts were tound in buffalo. Prevalence of hydatidosis in cattle was recoreded as 16.66% and 11.33% in buffalo. Fertility and viability of the cysts was observed microscopically. Out of 25 cysts of cattle. nine were fertile and out of 17 cysts of buffalo, only five were fertile.
Seroprevalence of hydatidosis in 150 butchers working in abattoir was also determined by the use of Latex agglutination test (LAT) kit for detection of hydatidosis.
The prevalence of Echinococcus is 24% which was derived from serum analysis of butchers.
DNA from hydatid cyst was extracted. Polymerase Chain Reaction was run on extracted DNA samples. Amplicon was run on 1% agarose for confirmation of size and specificity of product. Size of PCR product was approximately l300bp.
Genotyping of Echinococcus granulosus was performed through Polymerase Chain Reaction- Restriction Fragment Length Polymorphism (PCR-RFLP). The PCR-RFLP analysis of CO I gene of Echinococus was performed to confirm the strain of Echinococcus in cattle .The data obtained was analysed and it was concluded that the G5 strain of echinococus is prevalent in Cattle in Punjab area.
It is hoped that the findings of the present study will be helpful for further planning about the control of the disease and correlating the prevalence in cattles,buffalos and butchers from the zoonotic point of view.
According to the results, the PCR-RFLP analysis of samples of patients suspected for Echinococejis is a promising diagnostic method and also confirms the type of Echinococcits prevalent in that area and also enables an early direct detection of parasite DNA. This effort is a step to minimize the losses produced by this disease.

Publisher: 1990Dissertation note: Pakistan has a large population of livestock, which plays an important role in the economy of the country. Parasitism is a major problem in our country. Great economic losses have been attributed to the sheep population in our country due to the parasitic infections. The genus Trichuris includes some of the most important nematode species effecting the sheep, therefore a taxonomical study of the genus Trichuris was conducted in the month of September and October, 1989. For this purpose 100 guts (large intestine) of sheep slaughtered at Lahore abattoir were procured and brought to the parasitology laboratory College of Veterinary Sciences, for further investigations. The overall incidence of Trichuris spp. was found to be 74% . The following two species were recorded.
1. Trichuris ovis 66%
2. Trichuris globulosa 18%
Taxonomy of Trichuris species was studied by preparing permanent mounts. The present work was also aimed to see the effect of two commonly available anthelmintics namely fenbendazole (panacur) and albendazole (valbazen), on naturally infected sheep with gastrointestinal nematodes. Sixty sheep positive for nematode infections were randomly divided into three groups A,B & C each group comprising of 20 animals. Group A and B
were given fenbendazole and albendazole respectively according to the manufacturers dose rate while group C was kept as untreated control. The efficacy of both the drugs was evaluated on the bases of reduction of eggs per gram of faeces after medication. The egg counts were made on zero, 7th, 14th and 21st day. Both the drugs revealed a progressive decrease in the faecal egg counts. The efficacy of fenbendazole on 7th, .14th and 21st day was 96.33, 97.05 and 99.66% respectively while the efficacy of albendazole was 92.56, 95.37 and 98.18% respectively. There was no significant difference in the effectiveness of the drugs.

Material type: ; Format:
print
Publisher: 2009Dissertation note: Giardia is a protozoan parasite of the small intestine that causes extensive morbidity worldwide. Dairy calves can excrete high numbers of the cysts of Giardia and the disease in cattle is clinically important and can reduce the growth performance of the ruminants. Giardia is the cause of non-viral diarrhoea in humans and is responsible for epidemics in the developed and developing countries. The cyst is the infectious form, is ingested in contaminated water or food or directly from faecal-oral contact. Giardia duodenal is the only species, which is found in both humans and animals including dogs, cats, bovines, pigs, sheep and equine.
The present study was conducted to determine the prevalence in bovines at Military dairy farm, Gawala dairy colonies, the Government dairy farm and Household dairies in Lahore. The effect of season, sex, and age on infection rate and shedding of the cysts were also noted, and association of the Giardia infection with normal and abnormal stools was also studied.
Overall 2160 bovine faecal samples (720 buffaloes, 720 cattle and 720 calves) were examined during the study period from August 2007 to July 2008, amongst calves 362/720 (50.27%) were found to be positive. The highest prevalence was recorded in the Government. Dairy farm (68.33%) followed by Gawala colonies (55%), then the Military dairy farm (44.33%) and the lowest (34.44%) was recorded in Household dairies. Overall, highest (61.6%) seasonal prevalence was recorded during autumn, followed by spring (60.83%), then summer (53.4%) and the lowest
(34.1%) was recorded during winter. The highest (65%) prevalence was reported during August and the lowest (3 0%) during December.
Females were found to be more susceptible (56.74%) than males (35.1%). The prevalence was significantly higher (71.52%) in younger calves than the adults
(36.11%) (P<0.05).
Overall prevalence in cattle was 28.05%. The highest (41.67%) prevalence was recorded at the Government dairy farm, followed by Gawala colonies (32.72%), then the Military dairy farm (22.72%) and the lowest (15%) was recorded in Household dairies. The highest (35%) prevalence was found during August and the lowest (21%) during January. A significant difference (P<0.05) was noted. Females were found to be more susceptible (29.21%) than males (18.75%). The young calves had significantly higher (3 8.88%) prevalence as compared to the adults (24.44%).
Similarly, the overall prevalence in buffaloes was found to be 20.11% percent. The highest (40.55 %), prevalence was recorded at the Government Dairy Farm, followed by Gawala colonies (30%) then Military Dairy Farm (21.11%) and the lowest prevalence i.e. 12.77% was reported in Household Dairies. A non significant difference was recorded P>0.05). The highest (46.66 %) prevalence was recorded during August, while, the lowest (6.66%) during November and December. Females were found to be more susceptible than males. Where as the prevalence in a younger buffalo was significantly higher as compared to the adults.
Comparison of direct microscopic examination and PCR based methods was made at the Government dairy Farm, Gawala colonies; Military Dairy Farm and
Household Dairies. By direct Microscopic examination prevalence was found to be 28.05% (202/720) in cattle whereas by PCR it was 31.11%. Statistically analysis showed that the prevalence by PCR was significantly (P<0.05) higher than the microscopic examination.
It was observed that the highest prevalence of Giardiasis in bovines (Calves, Cattle and buffalo) was noted during August when the average temperature was 31.48°C. However the maximum and minimum temperatures were 35.37°C and
27.6°C, relative humidity 7 1.28% and rainfall was 3.2mm. The results of therapeutic trials by using albendazole, metronidazole, and mebendazole in cattle were calculated on the basis of reduction in the cysts count in the faeces after treatment.
Efficacy of albendazole at three dose levels i.e. 1 Omg/kg.b.wt, 1 5mg/kg.b.wt, 2Omg/kg.b.wt was 86.33%, 98.5% and 100% respectively, on day 27 after treatment. Efficacy of the metronidazole at 5Omg/kg.b.wt, 1 OOmg/kg.b.wt, and 1 5Omg/kg.b.wt. Was 85.42%, 87.8% and 94.02% respectively on day 27. Efficacy of mebendazole at three dosage level i.e. 7.5rng/kg.b.wt, lOmg/kg.b.wt and 2Omg/kg.b.wt was 81.15 %, 87.32%, and 90.4% on day 27 after treatment. Among these drugs, albendazole at
1 5mg/kg.body.weight was found to be most effective drug in the elimination Giardia infection. The significant (P<0.05) decrease in the CPG count after treatment in all the three groups and dose levels was noted. A significant difference (P<0.05) was observed in the level of leukocytes and of eosinophisl of infected cattle at day 06 and day 13 post inoculation. The leukocytes/lymphocytes count of Giardia infected cattle was 58.09%. Whereas, eosinophils constituted of leukocytes 9.69%. The total proteins of the sample were studied by sodium doedocyl sulphate polyacrylamide gel ELECTROPHORESIS (SDS PAGE). The result indicated that 8 diffeent molecular weight peptide badns were identified with size ranges from 20 to 70 KDa and common bands reported at 20, 24 and 35 K Da

Publisher: 2008Dissertation note: Schistosomiasis is one of the major diseases of public health and socio-economic importance in the developing countries of the world. Among human parasitic diseases, Schistosorniasis ranks second to malaria in tern-is of world wide public health risk. Keeping in view the importance of disease, the study was conducted to record the month wise and season wise prevalence of Schistosorniasis in buffaloes in four districts of the Punjab, province ie., Lahore, Sargodha, Kasur and Sheikhupura. The present study comprises of four parts.
Part I: deals with epidemiology of Schistosomiasis in buffaloes. Overall prevalence of Schistosomiasis in buffaloes, different farms of Punjab province indicated that infection was the highest (17%) at Kasur district followed by Sheikhupura (14.83), then Lahore (14.6%) and the lowest (13.66%) at Sargodha. The highest month wise prevalence was recorded during August (25.5%) followed by July where as the lowest during December and January.
Infection in buffaloes was higher in animals over two years of age (1 9%) than animals below two years of age (5%) in all the four districts of Punjab. The prevalence was higher in females (15.98%) than male (9.48%). There is variation in the prevalence as there is difference in the environmental and managemental condition of the area. For the serodiagnosis i.e. ELISA was used, the results indicated that the prevalence was lesser than the faecal examination because this was more specific and sensitive than the faecal examination.
Part 2: deals with the prevalence and ecology of snails. Various species of snails which act as the intermediate host of the Schistosomes were collected from the study area. The e of infection in the snails and role of cercariae in transmission of the disease was studied. A total of 10418 snails were collected of these 13.51 per cent were found to be infected. Among these 2350 were collected from Kasur district with infection rate of 14.51 percent followed, by Sheikhupura 2882 (13.6%) then Sargodha 2709 (13.40%) and the lowest at Lahore 2477 (12.51%). At Kasur district, genus wise prevalence of snails with infection rate indicated that Oncomelonia, indoplanorbis and Bullinus are the predominant genera with infection rate of 31.79, 17.10 and 14.46 percent respectively. However the highest number of the snails collected belonging to the genera Indoplanorbis. At Sheikhupura district, genus wide prevalence of snail indicated that Bullinus, Lymnaea, Indoplanorbis and Physa are the four prominent snails with infection rate of 24.74, 20.57, 14.66 and 13.84 percent respectively. At Sargodha district, genus wise prevalence of snails indicated that Lymnaea, Indoplanorbis, Bullinus and Physa are the four prominent snails with infection rate of 25.09, 14.29, 14.28 and 16.77 percent respectively. At Lahore district, genus wise prevalence of snails indicated that Bullinus Lymnaea, Physa and Indoplanorbis are the four prominent snails with infection rate of 23.37, 18.96, 13.97 and 12.70 percent respectively.While the prevalence at the snail level the Chi square value is 242.944 and the P-Value is 0.0000 1 which is highly significant.
Part 3: deals with the meteorological data ie, temperature, humidity, rainfall and pan evaporation with prevalence of snails and parasites. The temperature and rain fall play very important role in the spread of disease. The ideal temperature ranges form 22-25 °C where development within snail takes place in an efficient manner similarly humidity
f ranges from 55-70% is ideal for the development of the snail and the parasite. Rainfall is very important for the spread of the disease. There is a positive correlation of disease incidence to maximum and minimum temperature, humidity, and rainfall and pan evaporation. It was seen that during summer and autumn, optimum temperature, relative
humidity and rainfall play an important role for rapid propagation of the parasitic life
Part 4: deals with therapeutic trials against Schistosomiasis in buffaloes. A total of 150 animals (140 infected and 10 animals, normal) age ranged 5-9 years and of both sexes naturally infected with Schistosorniasis were used in thirteen controlled experiments. The efficacy of certain indigenous drugs, including Nigella sativa (Kalongi) , Caesalpinia
Crista (Karangwa), Lagenaria siceraria seeds (Kadoo ke Beej), Sausseria lappa (Qushte-e-Shreen) and Praziquanlel was compared with each other and control. Efficacy was quantified by determining the difference of egg per gram faeces (EPG) pre and post treatment. After the single dose of 50, 75 and 100 mg 1kg body weight of Nigella sativa (Kalongi) reduced EPG by 65.85, 68.29 and 71.79 per cent, respectively. After the second dose the respective reduction in EPG was 85.36, 92.68 and 94.87 percent. Caesalpenia crista at three dosage levels i.e.50, 75 and 100 mgI kg body weight caused 46.34, 53.65 and 59.52 percent reduction respectively while the reduction in EPO after second dose was 82.92, 90.24 and 92.85 percent respectively.

Publisher: 2010Dissertation note: Toxoplasmosis is caused by Toxoplasma gondii, an intracellular parasite which infects humans as well as wide variety of mammals and birds. Toxoplasmosis is found throughout the world and tends to be more prevalent in tropical climates. It is considered as one of the major public health disease. Risk of infection from turkeys, pigeons, ducks and quails to man is scarce, as they are intermediate hosts and are frequently infected by eating feed contaminated by cat faeces containing oocysts of T.gondii. The high seroprevalence in them could be related to large populations of homeless cats in the city and may suggests the significant role of urban pigeons in the epidemiology of toxoplasmosis.
A total of 200 serum samples were analyzed for anti-toxoplasma antibodies, of these 50 samples from ducks, 50 sampls from turkeys, 50 samples from pigeons and 50 samples from quails were collected at random. Under aseptic measures, 1-2 ml blood were withdrawn by venipuncture. All the serum samples wiere analyzed for specific IgG anti toxoplasma antibodies using Latex Agglutination Test (LAT). Positive reaction were visualized by naked eyes or magnifying hand lense.Commercially available Toxoplasma latex kit was used to determine the serum antibody. Results were interpretated. Data obtained was analyzed statistically by calculating the per cent sero-positivity of Toxoplasma gondii in ducks, turkeys, pigeons and quails.
In the present study the overall seroprevalence of T.gondii infection in pigeons, ducks, turkeys and quails is 8%, 12%, 16% and 4% respectively by using Latex Agglutination Test. In pigeons seroprevalence of T.gondii was 8% out of 50 pigeons examined one gave an antibody titer of 1:256, one was positive at 1:128, whereas two at 1:16 secreening dilution. In ducks seroprevalence of Toxoplasma gondii is 12% out of 50 ducks examined one gave an antibody titer of 1:256, two was positive at 1:128, whereas three at 1:16 secreening dilution. In turkeys seroprevalence of Toxoplasma gondii is 16% out of 50 turkeys examined three gave an antibody titer of 1:256, two was positive at 1:128, whereas three at 1:16 secreening dilution. In quails seroprevalence of Toxoplasma gondii is 12% out of 50 quails examined zero gave an antibody titer of 1:256, one was positive at 1:128, whereas one at 1:16 secreening dilution.

Publisher: 2010Dissertation note: Toxoplasmosis caused by Toxoplasma gondii is a widely distributed protozoan disease capable of infecting a variety of animal species. Felids, both domestic and wild, are capable of serving as definitive hosts, shedding T.gondii oocysts in their faeces.
People acquire toxoplasmosis posnatally by ingesting T.gondii oocysts from contaminated environments or by consuming T.gondii tissue cysts in inadequately meat products, raw meat containing tissue cysts or by ingestion of resistant oocysts from environmental matrices (soil, water, fruits and vegetables).
However, the impact of oocysts in toxoplasmosis epidemiology needs to be specified because they are suspected to be associated with T.gondii seroprevalence in some emerging outbreaks of acute toxoplasmosis in humans from soil or water. They are probably responsible for a significant part of infections in animals that could be later consumed by humans.
Detection of Toxoplasma gondii oocysts in environmental samples is great challenge as this coccidian parasite can be responsible for severe infections in humans and animals via ingestion of a single oocyst from contaminated water, soil, fruits or vegetables.
The present proposed study was designed to develop methods for the detection of oocysts
from Water, soil, food and parks environment.
The results of recovery test showed that it was possible to detect Tooplasma gondii parasite from water samples collected from various sources i e, drinking water from muncipility, lakes, pools, various reservoirs around farms and from tube wells. From the results ,The highest (13%) prevalence was reported from water around farms followed by lakes & pools (9%) then water reservoirs (7%) whereas the lowest from drinking water & tubewells i e 6 & 6 percent respectively.
A total of 250 samples of fruits and vegetables were collected for detection of T. gondii . From the results, it was noted that overall prevalence of T. gondii infection was higher in vegetables i e 5.6 % than fruits (4 %).
A total of 250 soil samples were collected from urban and rural areas. Of these 125 were from urban areas and 125 from rural areas. From the table-3 it was shown that the highest prevalence of T. gondii infection was noted in gardens and back yards of homes and gardens i e 20 & 20 % respectively. In these places cats often defecate and become a source of infection. Then followed by public enclosures where infection was 14.3%. The lowest i e 13.3% infection was noted at homes of urban areas.
T. gondii infection in rural areas indicated that It was highest (20% ) in home back yards followed by homes (16.7%) then public enclosure (14.5%) whereas the lowest (13.3%) at gardens of rural areas.

Publisher: 2009Dissertation note: Pigeons came from South Asia where they have selected for their flight ability. During the last 150 years, they have periodically been released in several sites as potential game birds but without success since they migrate away from the release point (Williams, 2000).
The present study was carried out at Lahore Zoo and University of Veterinary and Animal Sciences Lahore and postgraduate laboratory UVAS, Lahore. To record the prevalence of various nematodes of Pigeons, a total of 150 faecal samples were collected (75 reared at floor and 75 in cages) under different managemental conditions. Faecal samples were examined by three different techniques i.e. Direct smear, Flotation and Mc Master Egg counting technique. Out of 150 samples 33.5%) pigeonss were positive in cage system and (37.5%) were positive on floor system. Overall prevalence in both the systems of management was (35.5%).
Chemotherapeutic trails were conducted by using Albendazole and Mebendazole. For this purpose a total of 45 birds from the 105 positive birds were selected. These were randomly divided into three groups i.e. A, B and C having 15 birds in each group. l3irds in group A and B treated with Albendazole and Mebendazole. At their recommended dose rate respectively whereas birds in group C were not given any treatment. The efficacy of Albendazole and Mebendazole was 97.54% and 82.68% respectively.

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

Publisher: 2011Dissertation note: Coccidiosis is caused by various species of Eimeria. Avian coccidiosis is divided in two types (intestinal and caecal). Eimeria tenella and E. necatrix cause caecal eimeriosis.E.tenella is the most pathogenic species and its infection is causing huge economic losses to poultry industry world wide. In the present study, 400 caecal samples suspected for coccidiosis were collected from two districts (Kasur and Sheikhupura). Ten samples from twenty farms of each district were collected and examined for coccidiosis and species identication. The prevalence of coccidiosis was higher (65.25%) in both districts. Coccidiosis was found more prevalent in district Kasur (66.5%) as compared to Sheikhupura (63%). Eimeria species were identified by conventional methods like Direct Microscopy, Sedimentation technique, Floatation Technique and Sporulation.. The prevalence percentage of E.tenella and E,necatrix was found 67.5% and 12.25% respectively in 400 suspected caecal samples. E.tenella was more prevalent in district Kasur (67.5%) as compared to district Sheikhupura (63%). E.necatrix was also more prevalent in district Kasur (13%) than district Sheikhupura (11.5%). Protein profiling of all E. tenella strains was performed to check antigenic related ness between different isolates of E.tenella. More tan ninety percent isolates were antigenically identical which showed that E.tenella isolates in both districts were antigenically related.

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.

Publisher: 2011Dissertation note: The study was conducted to identify and compare the extent of gastrointestinal helminths in indigenous poultry and commercial layers. For this purpose, 200 gut samples (100 each from indigenous and commercial layers) were collected from different sources of Quetta district. All the material was brought to disease investigation lab, Quetta, for detailed postmortem and coprological examination.
The overall incidence of nematodes in indigenous chickens and commercial layers was 87% and 08% respectively. Three species of nematodes were recovered from both indigenous chickens and commercial layers. Ascaridia galli was the most common specie of nematodes recovered from small intestine while Heterakis gallinae and Subulura brumpti were isolated from the caeca of the sampled birds. The incidence of Ascaridia galli, Heterakis gallinae and Subulura brumpti was 75%, 25% and 16% in indigenous chickens and 06%, 04% and 03% in commercial layers respectively.
The overall incidence of cestodes was lower than those of the nematodes. It was found to be 78% in indigenous chickens and 05% in commercial layers respectively.
Five species of cestodes recorded from the gastrointestinal tract of indigenous chicken and were Raillietina tetragona (60%), Raillietina echinobothrida (21%), Raillietina cesticillus (14%), Cotugnia digonopora (29%) and Choanotaenia infundibulum (13%). On the other hand, following two species of cestodes were isolated from the gastrointestinal tract of commercial layers and included Raillietina tetragona (04%), and Choanotaenia infundibulum (02%).
Older birds have higher prevalence as compared with younger birds in indigenous and commercial layers. Slightly higher infection rates were recorded in females (51.7%) as compared with males (48.2%). On coprological examination, a greater proportion of birds were found infected with various helminthes and infection rate in indigenous birds was 66% as compared with commercial layers which was 3%.

Publisher: 2011Dissertation note: Pediculosis capitis is endemic parasite affecting many areas of the world. The objectives of my studies was to record prevalence of head lice in school children in Lahore.
A total of 500 primary school children examined for the prevalence of Pediculus capitis, aged 7-11 years and above. The child was declared as infected person if any head lice were detected either in the form of live or dead eggs, or nits.
The following characteristics were recorded for each child such as the sex, age, monthly income, family size, , pet ownership, parents' education, number of siblings, frequency of hair washing and presence or absence of social security of the family were recorded for all children
Pediculosis capitis was recorded in 387 (77%) children. The prevalence of head lice infestation was significantly more in girls (85%) than in boys (52%).
Among school girls, the head lice infestation rates in Low, Middle and High socio-economic groups were 96%, 85% and 71% respectively. Among school boys, the prevalence of head lice rates in Low, Middle and High socio-economic groups were 60%, 50% and 36% respectively.
Children of age 9-10 years and those age 11 years exhibited a significantly low prevalence than those of age 7-8 years.
Some variables were found to be significantly related to head lice infestation such as sex, pet ownership, age, parent's education level and hair length. This study shows that major factor influencing the occurrence of Pediculosis is socio-economic status among school children of both sexes (male and female) in the Lahore.
The results of this study was shows that the prevalence of head lice infestation (pediculosis capitis) is high in Lahore, and is found in all investigated schools regardless of personal hygiene and socio-economic status.

Publisher: 2011Dissertation note: Some intestinal parasitosis pathogen have potential is well known, many of them not shows symptoms, due to the body immunity and climatic element (Vinayak et al. 1990). While other shows like B. hominis and C. parvum. Persistent and acute diarrhea has been linked with the Giardia duodenalis and Entamoeba histolytica. Entamoeba / dispar, a protozoa having alike character with E. histolytica which is a not involve in causing diseases but proved symbiotic association in gut, not harms the other.
Children up to age of 3 years commonly found with anemia and iron deficiency due to malnutrition caused by high prevalence of parasitosis. (Kapur et al., 2001)
Cryptosporidium parvum within age of 5 years children gave highest prevalence rates in a community, among different parasites (Palmer & Biffin 1990). Cryptosporidium spp have been causative agent of persistent and acute diarrhea in many research works (Lima et al. 1992).
In developing countries intestinal parasitosis infection is a major health issue by promote health standards and controlling the carriers or vector, most countries have successfully reduced the rates of infestation. However, in developing countries geographic, socio-economic factors and natural calamity increase the health problems. Countries, which are geographically located in hot and humid areas along with poverty, unavailability of clean water, malnutrition, and high population density provide maximum chances for the development and high intestinal parasitic risk. Because of lack of sufficient research and attention of infectious and parasitic diseases in developing countries is the main problem hurdle to eliminating the risk of parasitic infestation.( Sayyari et al.,2005)
Pakistan estimated the intestinal parasitosis as the important public health problem. In developing countries intestinal parasitosis infection is a major health issue by promote health standards and controlling the carriers or vector, most countries have successfully reduced the rates of infestation. However, in developing countries geographic, socio-economic factors and natural calamity increase the health problems. Intestinal parasitosis is most familiar in children due to lack of hygienic condition. Physiologist and medical specialists are recommended that parasitosis infections delay children's growth, malnutrition, lost the opportunities of education and development. The under study carried out to record the prevalence of intestinal parasitosis within children at day care centers of Lahore and also to relate environmental factors with socio-economic status.
The basic purpose for collection of stool specimens were to examined the parasitic eggs, cysts, and larvae, by different methods like fresh smears method and Scotch tape method. Trophozoites of amoeba were examined in fresh smears. Oxyure eggs were seen in Scotch tape slides. The parasitic size was measured by ocular micrometry method. Formaline ether concentrate method was being done for finding cysts (Machado,1999 ; Lotphy 1990). Socio- economic and environmental factors were also is studied.
Of 174 children 56 children studies positive for parasitosis, 96 were males and 78 females. One or more intestinal parasites were identified in 40 (22.9% children) the most pravelent parasite were E. vermicularis 9.19% G. lamblia 6.89% E.histolytica 5.17% A.lumbricoides 2.87% H.nana 1.14% T. saginata1.72% T.trichiura 4.59% and E.coli 0.57% showed a low infection respectively

Publisher: 2011Dissertation note: Helminthic infections causing anemia are the major public health problems globally. Intestinal parasites are most prevalent in tropical countries. Tropical countries have mild climate and heavy rains which are breeding grounds for parasites.
The present study was conducted to determine the frequency of intestinal helminthic infections in two to twelve years old children at three different hospitals of lahore. For this purpose, a total of 250 stool samples were examined for the presence of various endoparasites. Stool samples were examined by direct smear and floatation techniques. Identification of eggs was made on the basis of morphological characteristics.
250 blood samples of the same children were also collected for the determination of haemoglobin level. Haemoglobin determination was done by haematology analyzer (Sysmex- model number KX-21). In this way association of parasitic infections with anemia was done.
Prevalence of intestinal parasitic infections was noted in children according to age and gender, among different hospitals of lahore and among children whose family members had received different levels of education. The present study has also dealt with the relationship between haemoglobin levels along with their means and standard deviation.
Out of the total 250 stool samples examined, it was found that 29 samples were infected with a prevalence of (11.6%). Out of these 29 samples, there were 13(44.82%) cases of Ascaris lumbricoides, 8(27.58%) cases of Hymenolepis nana, 6(20.68%) cases of Taenia saginata and 2(6.89%) cases of Hookworm. The level of haemoglobin in these children ranged from 3.7gm/dl to 9.8 gm/dl. This indicates that there is a relationship between helminthiasis and anemia.

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.

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.

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.

Publisher: 2012Dissertation note: Goat rearing is a traditional activity in peri-urban areas and villages and plays an important role in the nutrition, social and economic needs of the population. Gastrointestinal nematodes are common in various production systems and these infections are the single most significant constraint to small ruminant productivity.
The present study was carried out at Saidu Sharif, District Swat to generate data about the gastrointestinal (GIT) nematodes prevalent in the area. To record the prevalence of various nematodes of goats, a total of 150 faecal samples were examined. A total of 61/150 (40.67 %) of samples were found positive. Different species were identified and included Nematodirus spathiger (28.66 %), Haemonchus contortus (14.66 %), Trichostrongylus spp (4 %), Strongyloides papillosus (6 %) and Trichuris ovis (11.33 %). Highest prevalence of GIT nematodes were found in young and immature animals (48 %) with mean EPG 282 and 211 respectively. Adult had lower infection rate (26 %) with mean EPG of 142. Sex related prevalence indicated that male had higher prevalence (46.66 %) than female (34.66 %) and greater intensity of infection in males as compare to females. Higher infection rate with GIT nematodes was recorded in pregnant goat (42 %) as compared to non pregnant (33.92 %). House hold animals showed high infection rate i.e. 45.33 % with mean EPG of 254 as compared to commercially raised animals which had infection rate 36 % with mean EPG of 169. The Study

showed significant difference of egg per gram count between breeds. Beetal goats had high infection rate (100 %) and intensity as compared with other breeds.
Higher egg shedding was recorded in animals around parturition as compared to dry goats. Liter size also effected the EPG and higher counts were recorded in goats with duplets and triplets.
Albasym (Albendazole) was evaluated at two dose levels i.e. 1 ml/ 20 kg body weight and 1.25 ml/20 kg body weight. The efficacy at normal dose and higher dose at day 7th was 98.81 % and 100 % respectively, at day 14th 95.24 % and 99.53 % and at day 28th 80.95 % and 93.90 % respectively. No significant difference at normal dose and higher dose was observed while significant difference with control group was recorded.

Publisher: 2012Dissertation note: Trichomonas foetus (T. foetus) is a protozoan parasite of reproductive tract of large ruminants and causes abortion. This organism is found in males and females associated with varied pathology and clinical symptom. Disease has venereal transmission and male remain infected throughout the life. Pakistan is a developing country and artificial insemination facility is not available to all farmers and some are reluctant to avail it.
This study was designed to check the prevalence of T. foetus in large animals in district Hafizabad. One hundred and fifty preputial and vaginal samples were collected from cattle and buffaloes 75 each. These samples were from 100 females and 50 males. Vaginal mucus from females was thoroughly examined for T. foetus in direct smear and in smear stained by Giemsa stain. Male samples were subjected to examination by direct smear, centrifugation and stained smear performed from sediments for detection of T. foetus. Overall prevalence of T. foetus was 12.0% (18/150) in sampled animals and species wise T. foetus infection was 8% (6/75) for cattle and 16% (12/75) for buffalos. Sex related prevalence of T. foetus in cows is 6% (3/50) and in buffaloes was 14% (7/50). Infection was more common in buffalo bulls 20% (5/25) as compared with cow bulls 12% (3/25).
There was no difference in diagnosis of T. foetus in females by direct smear or by examination of stained smears. Whereas stained smears prepared from sediments of preputial washings were more sensitive in diagnosing of T. foetus infection as compared with direct smear method. Study also indicated that infection was exclusively seen in animals that were involved in natural breeding.
