Publisher: 1998Dissertation note: The study was conducted to determine the prevalence of genus trypanosome and the effects of natural infection on some blood parameters in dogs.
For this purpose blood samples of 500 pet dogs (250 adult dogs and 250 pups) were examined at Dog Hospital, College of Veterinary Sciences, Lahore. Giemsa staining procedure was admpted to stain glass slides having blood smears made from blood samples.
Out of 500 ogs, 30 dog were found positive for tryponosomiasis. It revealed that only 6% prevalence of trypanosomiasis in dogs was estimated. In case of adult dogs out of 250 dogs, 13 dogs (5.2%) and in pups out of 250 dogs, 17 dog (6.2%) were found trypanosome infected. So pups were found more susceptible as compared to adult dogs. During research it was also noticed that mot of the dogs which were found positive being kept with horses.
Then blood samples of 10 adult dogs and pups each which wre positive for trypanosomiasis and 10 adult dogs and pups each which were healty (as control) were further examined for the estimation of haemoglobin paced cell volum, erythrocytes sedimentation rate and total serum protein to check the effects of natural infection on mentioned blood parameters.
The blood parameters of trypanosome infected and healthy adult dogs were compared and similarly blood parameters of trypanosome infected and healthy pups were compared. For this comparison unpaired 't' test was applied. By calculation it was found that haemoglobin, packed cell volume and total serum protein of trypanosome infected adult dogs and pups were significantly decreased as compared to healthy adult dogs and pups, respectively. But the erythrocytes sedimentation rate was found significlantly increased in case of trypanosome infected adult dogs and pups as compared to healty, adult dogs and pups.

Publisher: 1999Dissertation note: The present study was conducted to see the effects of the experimentally induced coccidiosis on weight gain and some blood parameters and its control with medication and vaccination. For this purpose, 150 day-old quail chicks were purchased from the local hatchery and were reared under control managemental and coccidiosis free condition upto the 42 days of experiment. A commercial coccidiostat free feed and drinking water were provided ci libitum throughout the experiment. The birds were divided in five separate groups i.e. A, B, C, D and E, each comprising of 30 birds. Group A was kept as a non-infected, non-medicated and non- vaccinated. The chicks of groups B, C, D and E, were administered 50,000 oocysts of. tenella directly into the crop at the 18 days of age, the chicks in group C were immunized against coccidiosis with a locally prepared vaccine on 3rd and 10th day of age, while those of group D with an imported coccidiosis vaccine (Coccivac) on 7th day of age. The chicks of group E were medicated with Salinomycin on the appearance of clinical symptoms and OPG of the infected birds.
No oocysts were seen in the droppings of group A chicks, throughout the experiment, while group B, chicks had the highest OPG count after induction of infection, the highest peak being in the 3rd week post-infection.
The highest mortality recorded in the infected B group and low in other infected C, D and E groups and highest mortality in 3rd week of induced infection in all infected groups.
The birds in groups A and E attained highest weight gain as compared with groups B, C and D but the difference was non significant.
The lowest Hb and TEC values were recorded in infected group B, while in other infected groups C, D and E both these values were also decreased but comparatively lesser than B group. Similarly, values of TLC were increased in infected group B as compared with other infected groups i.e. C, D and E and the difference was statistically significant.
In case of differential leukocyte counts there were increased heterophil and monocytes values in group B, while decreased values lymphocytes, basophils and eosinophils were recorded in other infected groups than the other i.e. C, D and E.
The postmortem lesions observed were swollen intestines petechial haemorrhages on the wall of the intestine and dehydrated liver and lungs in infected carcasses.

Publisher: 2000Dissertation note: The present study was conducted between November 1999 and January 2000 to find out the prevalence and to study the taxonomy of haemoparasites of horses. In addition, their effect on haematological parameters was also studied.
A total of 40 out of 435 horses were found positive for haemoparasites. The prevalence recorded was 9.20%. Out of positive animals 22(5.06%) were positive for babesia species, of which 10 (45.45%) were infected with B. equi, 6 (27.27%) were infected with B. caballi and 6 (27.27%) were positive with mixed infection of B.qui and B. caballi. out of remaining positive cases, 14 (3.22%) were positive for T.evansi and 4 (0.92%) were positive for P.multipapillosa.
Animals of group A, belonged to all the places of other groups. Animals of group B showed 10.52 % prevalence for haemoparasites, Babesia species was present in 6 (6.3l%) and T.envansi was present in 4 (4.2l%) animals respectively. Horses of group C showed prevalence as 14.28% haemoparasites out of which 6(8.57%) were positive for babesia species, and 4 (5.71%) positive for T.evansi . Similarly, animals in group D, indicated 11.11 % prevalence of haemoparasites including babesia species 3 (3.33%), T.evansi 3 (3.3%) and P.multipapillosa, 4 (4.44%) respectively. Ten out of 180 (5.56%) horses of group E were positive for haemoparasites and 7 (3.89%) were positive for Babesia spp. and 3 (1.66%) were positive for I.evansi.
Haematological examination revealed a significant decrease (P<0.05) in the total erythrocyte count, total leukocyte count, haemoglobin estimation, packed cell volume, neutrophils and basophils in the infected horses as compared with healthy horses. However, there was a significant increase (P<0.05) in lymphocytes and eosinophils in the infected horses as compared with healthy horses of group A.
From the results of the present study it may be concluded that the horses belonging to the poor community need due attention for the control of haemoparasite diseases. Services must be extended to educate owners of these Tonga ponies for the control of haemoparasitic diseases and their vectors.

Publisher: 2000Dissertation note: The present study was carried out to determine the incidence and taxonomy of various gastric amphistomes in buffaloes and cattle. I addition the effect of these amphistomes on different haematological parameters (TEC, PCV, Hb, ESR and DLC) was carried out.
For this purpose 151 compound stomachs (70 buffaloes and 81 cattle) of slaughtered ruminants were examined at Lahore abattoirs. The worms were collected and identified and taxonomical findings were recorded. In addition, faecal samples from the positive cases were also collected and examined to record the EPG count. The blood samples were also collected from the above mentioned animals to study the effect on different haematological parameters. The animals awaiting slaughter were selected irrespective of age and sex.
A total of 70 buffaloes and 81 cattle had to be examined to obtain the 50 positive buffaloes and 50 positive cattle, infected with different species of amphistomes. The overall incidence of amphistomes was found to be 71.42% in buffaloes and 61.72% in cattle.
The various species of gastric trêmatodes identified were as follow i.e. Paramphistomum cervi, Cotylophoron cotylophorum, Gastrothvlax crumenifer and Carmverius spatiosus. The incidence of . cervi infection was higher both in buffaloes (54.48%) and in cattle (44.34%) as compared with the other species of the family Paramphistomatidae. The incidence of Cotvlophoron cotylophorum was found to be 50% in buffaloes and 39.5% in cattle. The incidence rate of Gastrothylax crumenifer and Carmyerius spatiosus was found to be 38.57% and 28.57% in buffaloes while 29.62% and 19.75% in cattle respectively.
The EPG of affected buffaloes and cattle carcasses was also undertaken and the average EPG recorded was 44.67 eggs/gram in buffaloes and 39.78 eggs/gram in cattle.
Haematological findings revealed that the Hb, PCV and TEC were decreased while the neutrophils and eosinophils were increased both in buffaloes and cattle suffering from amphistomiasis.

Publisher: 2001Dissertation note: The study was undertaken to find out the comparative efficacy of Phenothiazine, levamisole and Ivermectin against GIT nematodes in horses at Lahore. For the purpose one hundred horses irrespective 'of age, breed and sex were exam for the presence of various species of gastro-intestinal nematodes in horses. The coprological examination showed a positive percentage of 64% while 36 cases (36%) were found to be negative. The positive cases had mixed infestation of large and small strongyIids, Parascaris equorum and Oxyuris equi species. Forty naturally infested horses divided in four groups (A, B, C and D), were selected for the drug trial. The drugs used were Phenothiazine @ 55 mg/kg body weight, levamisole @ 7.5 mg/kg body weight (1 mI/2 kg b.w) Ivermectin @ 0.2 mg/kg body weight to the groups A, B, C and D, while the animals of group D acted as non-medicated control.
The mean EPG count was carried out pre-medication and post medication of the said anthelmintics.
Based upon EPG count, conducted on 3rd, 7th and 14th day for each anthelmintic; it was revealed that the mean EPG count of group A (Phenothiazine) showed 62.99, 82.67 and 95.27% reduction in ova output while the animals of group D (medicated with levamisole exhibited 53, 82 and 93% reduction in the said equines). The group C (medicated with Ivermectin showed reduction ofEPG as 79.83,95.16 and 100% on 3rd, 7th and 14th day post medication).
From the results of this study it is concluded that Ivermectin was the most effective as compared to Phenothiazine and levamisole. Therefore, it is stressed that Ivermectin should be used in equines for the effective control of gastro intestinal nematodes. The drug is quite safe and without any adverse effects on these animals.

Publisher: 2000Dissertation note: The study was designed to look into the comparative efficacy of different prophylactic measure against coccidiosis in broilers. One hundred and fifty, day old broiler chickens were reared under controlled conditions. They were equally divided into five groups, on day 1, i.e. A, B, C, D and E. Group 'A' was kept as uninfected, unmedicated control whereas all other test groups B, C, D and E were infected with 30,000 sporulated virulent oocysts. Group 'B' acted as infected and unmedicated control at day 20 and 30 of age. Group 'C' acted as infected and treated with Diasul-S at the rate of 1/2 gm/lit of drinking water for 3 days and group 'D' was treated with coxicure A-K at the rate of 1/4 gm/lit drinking water for 3days. The birds of group E received locally prepared Eimeria tenella vaccine (ETV) on day 3 and 10 of age of birds.
No coccidiosis in the birds of group A and E was noted through out the experiment. The oocysts per gram (OPG) of faeces in group A and E was nil Members of group 'B' showed the highest counts than any other group. The birds of group 'C' and 'D' showed the moderate counts but towards the completion of experiment, the OPG counts gradually reduced in both groups.
Weekly average weight gain record showed that average weight gain by the birds of group 'A' were the highest as compared with all other groups. The average weight gain of group E showed the second highest weight gains. The members of group 'B' showed the lowest weight gains while the members of groups 'C' and 'D' were ranked as 3rd and 4th in weight gains. The weight gains observed in groups A, C, D and E as compared with groups B were significantly higher (PO.O5) N. P.. In groups 'A', 'C' and 'E' the morbidity was nil. While in groups 'B' 30% morbidity was observed. Group 'D' showed low morbidity and one bird died due to coccidiosis.
The best feed conversion ratio (FCR) was observed in groups 'A' and followed by groups 'E', 'C' and 'D'. The feed conversion ratio in groups 'C' and 'D' was equally good. Worst feed conversion ratio was observed in group 'B'.

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.

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.

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: The present studies were conducted on the prevalence and chemotherapy of hypodermosis in cattle and buffaloes in D.G. Khan and Rajanpur districts of Punjab (Pakistan). Studies included assessment of prevalence of hypodermosis in the Veterinary hospital, houses holds, study fields and Livestock farms, the second part of the studies comprised of chemotherapy of hypodermosis. The prevalence of hypodermosis in cattle examined in Veterinary hospital, house holds, study fields and livestock farms in D.G. Khan and Rajanpur districts were recorded as 18.75%, 15.25% and in buffaloes the prevalence were recorded as 6.25% and 6.00%.
Chemotherapeutic trial of two insecticidal drugs Viz Ivermectin (1%) at a dose rate of 0.2 mg/kg body weight subcutaneous injection and Neguvon (Trichlorophon) at a dose rate of 5 gram in one litre water topical application was carried out to evaluate their
efficacy against hypodermosis in cattle and buffaloes. Ivermectin was found to be 100% and Neguvon 90%( Trichlorophon) effective for the control of hypodermosis. During the studies the economic losses were also studies and it has found that 50% loss to the local hide merchants in the area.
Investigations on the estimation of economic losses based on the infested hides were carried out in Dera Ghazi Khan and Rajanpur Districts. Twenty hide merchants in different areas were interrogated to find out the prices of warbled and warble-free hides. This price index was used to estimate the economic losses in terms of rupees.

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: 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.

Detection Of Toxoplasma Gondii From Water And Matrices (Soil,Fruits &
by Adeela Ajmal | Prf.Dr. Azhar Maqbool | Dr. Kamran ashraf | Dr.Aftab ahmad | Faculty of Veterinary Sciences.
Material type: ; Format:

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: 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.

Publisher: 2011Dissertation note: Caecl coccidiosis is caused by Eimeria tenella and E. necatrix and poultry industry is facing huge economic losses due to this infection world wide. Eimeria tenella is the most common cause of caecal coccidiosis but E. necatrix is also isolated rarely. In the present study, 400 caecal samples suspected for coccidiosis were collected from two districts (Lahore and Gujranwala). Ten samples from twenty farms of each district were collected and examined for coccidiosis and species identication. Prevalence of coccidiosis was found 68%. It was more prevalent in district Gujranwala (71.5%) as compared to Lahore (64.5%). Eimeria species were identified by conventional (Direct Microscopy, Sedimentation technique, Floatation Technique and Sporulation) and molecular technique (PCR). Polymerase chain reaction was found the most sensitive ands accurate technique for species identification as compared to all conventional techniques. The prevalence percentage of E.tenella and E,necatrix was found 68% and 12.5% respectively. E.tenella was more prevalent in district Gujranwala (71.5%) as compared to district Lahore (64.5%). E.necatrix was also more prevalent in district Gujranwala (13.5%) than district Lahore (11.5%). The difference in percent prevalence of coccidiosis and species of Eimeria may be due to difference in farm management, farming type, biosecurity measures.

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: 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.

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

Publisher: 2012Dissertation note: The main area of research in this study was to assess the prevalence, hematological and serological aspects of ovine nematodiasis. Four main experiments were conducted to highlight the objectives of the present research study.
First experiment was conducted to find out the prevalence of sheep major nematodes for one year (January-December 2011). For this purpose three sheep breeds i.e., Balochi, Babrik and Harnai (either sex and between 1-5 years age groups)were selected randomly from three sites i.e., Quetta, Ziarat and Loralai. Faecal analyses of these sheep showed overall higher (40.25%) nematodes prevalence at Loralai followed by Ziarat (29%) and Quetta (23.92%). Five nematodes infection were recorded at three experimental sites. Among these, H. contortus (5.58 to 10.42%)and was the higher prevalent followed by N. battus (6.92 to 9.33%), S. papillosus (4.42 to 9%), T. colubriformis (2.33 to 7.33%) and T. ovis (1.83 to 6.83%).The nematodes prevalence was higher in one and five years old sheep. The female-sheep were infected with higher nematode prevalence higher the than male once and sometimes non-significant difference. These five nematodes were prevalent almost throughout the year; however, a peak infection was recorded during August/September. The high temperature, rainfall and humidity during these months may be predisposing factor of higher prevalence.
Second experiment was on diagnosis of sheep nematodiasis through Enzyme-linked immunosorbent assay (ELISA). For this purpose H. contortus and T. ovis positive samples (200) based on coprological examination were also indicated 100% positive sensitivity by the ELISA based on crude somatic antigen, while on excretory antigen based showed lower (92%) sensitivity. The sera (n=200) of non-infected sheep (based on coprological examination) showed marked difference results. Such as 168 (84%) and 166 (83%) samples were found positive with H. contortus and T. ovis, respectively. While, based on crude somatic antigen 158 (79%) and 144 (72%) samples were found positive with H. contortus and T. ovis, respectively.
Third experiment was conducted to determine the hematological values and total serum protein indices in healthy and nematodes infected sheep. The statistically significant (P<0.05) difference in PCV, Hb, RBC, WBC, Eosinophil, ESR and Total serum protein values was observed among healthy and nematode infected sheep groups. While, there was no statistically significant (P<0.05) difference in TLC, Lymphocytes, Neutrophil, Monocytes and Basophils counts in healthy and nematodes infected sheep groups.
Fourth experiment was conducted on assessing the comparative efficacy of synthetic (Oxfendazole and Ivermectin) and locally manufactured herbal medicine (Deedani, Kirmar and Atreefal Deedan) anthelmintics against sheep nematodes at AZRC/PARC Range-livestock Research Station Sanjavi district Ziarat. The present study results regarding the comparative efficacy showed that, Atreefal deedan among herbal products (Deedani and Kirmar) and Ivermectin than Oxfendazole was found effective against sheep nematodes. The sheep treated with Ivermectin showed highest (96%) FEC reduction, followed by Oxfendazole/Atreefal deedan (86%), Kirmar (60%) and Deedani (32%).

Publisher: 2014Dissertation note: Vector-borne diseases are among the major causes of illness, death and economic losses particularly in tropical and subtropical areas of the world. Mosquitoes are most important single group of insects, transmitting wide range of human diseases like malaria, Japanese encephalitis, dengue fever, yellow fever, filariasis and several other infectious diseases. Malaria is a major global public health problem. Several Anopheline species are prevalent in Pakistan among which Anopheles stephensi and Anopheles culicifacies are confirmed vector of Plasmodium. An. subpictus is a confirmed secondary vector of malaria in many countries. A wide range of this species is also distributed in Pakistan. The aim of the present study was to determine the vectorial role of An. subpictus in the transmission of malaria in Pakistan through microscopy and polymerase chain reaction (PCR).
After species identification, the mosquitoes were examined microscopically and were found negative for the presence of human Plasmodium sporozoites. The DNA extracted from An. subpictus was subjected to PCR but no Plasmodium specific amplification was observed. Keeping in view the sample size, it was concluded that further study is required with even large sample size before declaring that An. subpictus is not a vector of Plasmodium in Pakistan.

Publisher: 2013Dissertation note: Mosquito are major vectors, considering the havoc they play by transmitting many diseases which have greatly affected human beings worldwide. The ecological, socioeconomic conditions of different regions and the emergence of insecticide resistance in main vectors are strongly responsible for determining the geographical distributions and incidence of vector-borne diseases. Among mosquitoes, Anopheles species are responsible for transmission of filariasis, Japanese encephalitis virus and malaria in subtropical region. An. subpictus is a confirmed vector in many countries of South and Southeast Asia. The present study was designed due to limited earlier records regarding insecticide susceptibility status of An. subpictus from district Kasur, Punjab. During the first half of the study, three insecticides i.e. DDT 4%, deltamethrin 0.05% and permethrin 0.75% were testing by using WHO susceptibility bioassay. A total approximately (n=1000) different types of mosquitoes were caught from district Kasur. Mosquitoes belonging to three genra Anopheles, Culex and Aedes were found in our collection. After species identification, An. subpictus was separated for further processing. It was highly abundant species among Anophelines species captured. Field collected adult blood fed females of An. subpictus was reared in the insectary for F1 generation. Two to three days old non engorged adults of An. subpictus were evaluated by using WHO susceptibility bioassays. Both male and female mosquitoes have shown resistance against all three insecticides tested. Probit analysis was used to check the time-response values. Percentage mortalities were recorded against DDT, deltamethrin and permethrin (mortality range 29.47 %-76.28 %.) with higher KT50 and KT95 values.Second half of the study was undertaken to quantify detoxifying enzymes in An. subpictus following WHO biochmical assays. Biochemical analysis of detoxifying enzymes in An. subpictus has revealed that there is significant alteration/elevation of metabolic enzymes when compared with the lab strain might be a contributing factor in conferring insecticides resistance. Elevated levels of GST (0.469 ± 0.115), MFOs (11.665 ± 4.165), ? esterases (1.5808 ± 0.7657) and ? esterase (3.9682 ± 2.311) were detected in An. subpictus. There was a significant high alteration of AChE enzyme activity detected in this species with 57.52% (± 9.234) mean percentage propoxur inhibition. These enzymes are implicated in the metabolism of DDT, pyrethroids and carbamate insecticides.

Publisher: 2015Dissertation note: A camel is a very hardy ruminant animal, which can survive under harsh climatic
conditions very effectively by utilizing the marginal areas with excellent capabilities and produce
under such conditions (Hjort and Hussein, 1986; Abbas and Tilley, 1990). Camel is an important
animal as it is well adopted in unique manners in the hot, arid and semi-arid environments
(Schwartz, 1992). It can survive without water and food for many days and this unique ability of
camel makes it an ideal for such harsh conditions for which it is also commonly known as “The
Desert Ship”. In spite of the fact that camel is an important member of a group of animals which
produces food for human consumption in the shape of milk and meat, yet it is the most neglected
one in the field of scientific research. It may be due to the fact that camel belongs to such areas
of the world which are arid, semi-arid or rain fed in nature, having harsh climatic conditions,
where poor nutrition and poor management are the major issues (Sohail, 1983).
It is an established fact that diseases originating from parasites lead to the main health
hazard issues in animals. These parasites survive at the expense of the host animals causing lot of
health problems, like skin irritation, anemia leading to weakness and debility. Some of the
parasites have zoonotic importance and may become a source for the transfer of many contagious
diseases like scabies to the human beings (Dominguez et al. 1978). McClain et al. 2009,
observed the scabies as a major health problem globally both for humans and animal population.
Sarcoptes scabiei is an ectoparasite which is a cause of scabies, a skin problem in the human
beings worldwide and the similar species of mites do also produce a similar type of disease in a
large variety of wild and domesticated mammals (Pence and Ueckermann, 2002; Fitzgerald et
al. 2004). Fain, 1978, reported that more than fifteen (15) different species of Sarcoptes scabiei
morphologically and genetically distinct from each other have been identified in different hosts.
Introduction

Sarcoptic mange is the second important problematic disease of camel after
Trypanosomiasis (Nayel and Abu-Samra, 1986). Scabies caused by Sarcoptes scabiei var cameli
is a serious & highly contagious skin problem and also economically important disease of the
camels (Pegram and Higgins, 1992). Camels, which are reared with deficient nutrition, poor
management and under unhygienic conditions are mostly affected by this disease (Kumar et al.
1992).
A large group of people and communities living in arid diverse ecozones in the entire
world, particularly in harsh climates earns their livelihoods by depending on camels. This
dependence may spread to the utilization of camel milk, meat, wool and leather besides its use in
transportation, riding and sports (Wilson, 1984; Snow et al. 1992). In Pakistan camels are also
raised by the people for meat, milk, riding, transportation and sports purposes in the deserts, semi
desert & rain-fed / warm areas of the entire country being a hardy animal as it can tolerate easily
the rugged climate as well as extremes of temperatures of such areas.
The natural harsh and adverse climatic conditions, particularly during long dry seasons
lead to a paucity of feeding regimes resultantly the camels raised in such areas are subjected to
stress conditions which lower their resistance and make them easily vulnerable to diseases
(Abbas et al. 1993; Agab, 1993). Abbas & Tilley, 1990; Saint-Martin et al. 1992; Abbas and
Agab, 2002; Pathak and Chhabra, 2010; while reviewing the parasites & parasitic diseases of
camel population in India were of the opinion that Sarcoptic mange is a serious, debilitating,
dreaded and widely prevalent disease of camels in India.
Besides other infectious diseases of bacterial and viral origin, camels are exposed to a
wide range of internal & external parasitic infestations. Amongst other so many external
parasites to which camels are exposed, the Sarcoptic mange is recognized to be one of the most
Introduction

serious and damaging disease. This disease is caused by a mite known as Sarcoptes scabiei var
cameli which belongs to genus Camelus of SARCOPTIDAE family in Veterinary Entomology.
It is an extremely pruritic, contagious and debilitating skin disease which is very
frequently and sudden in onset. It is also ranked as one of the most serious and important disease
of the camels. Sarcoptic mange infestation is very common in the areas of thin skin, the head,
neck, flanks, medial aspect of thighs or inguinal region, mammary glands and prepuce. The head
is usually affected very rapidly as the animal uses its teeth for scratching the affected areas.
Besides linking the occurrence of the disease with poor camel management, malnutrition and
contact with infected objects, the stray & infected camels also often become a focus of infecting
the healthy animals when mingling with them particularly at watering places for drinking
purpose (Richard, 1987; Abdel-Rehman et al. 2001).
Sarcoptes is a burrowing mite as it penetrates deeply through the skin surface of the
infected camel. This burrowing of mites in the skin helps these parasites lead to intense pruritus
and exudative dermatitis. In pruritus, mites penetrate deep into muscular areas, damaging the
flesh and lowering the quality of meat. The early inflammatory reaction of the host body towards
the mites becomes evident in the shape of small popular elevations, invasion and injuries leading
to formation of hairless areas, scaly crust formation or scabs on the affected parts and the skin
become dark and thickened. Skin of mangy camel show hemorrhages, and subcutaneous odema
after the development of fissures in the underlying epidermis (Kumar et al. 1992; Amer et al.
2006).
The fertilized female mites create winding burrows or tunnels in the upper layers of the
epidermis of the skin of the host animal and feeding on the serous exudate, a liquid oozing from
the damaged tissues. The female mites lay about 40-50 fertilized eggs in these tunnels which
Introduction
4
hatch in 3-5 days into a six legged larvae. These larvae immediately crawl to the surface and
burrow themselves in the superficial layers of the skin and create small molting pockets. In these
molting pockets, the larvae molt to next stages of nymph and adult. The adult male then emerges
and seeks a female either in the molting pocket or on the surface of skin. After fertilization the
female produces new tunnels, either de novo or, by extension, of the molting pockets, lays eggs
in these tunnels and a new life cycle starts. The entire life cycle of Sarcoptic mange is completed
in 17-21 days.
New hosts can be infected through direct transmission by contact between the animals,
presumably from larvae, nymph or adult mites, which are commonly present on the skin surface
of the infected animal. Indirect transmission of infestation can also take place through the objects
or fomites having mange infection, which come into contact with the affected camel, such as
harnesses, blankets, baggage tack, tents and tree trunks (Richards, 1987). The pruritus increases
as the mites penetrate deeper in the skin (Al-Rawashdeh et al. 2000, Driot et al. 2011, Bekele et
al. 2012). Based on the rate of infection camels can be seriously disturbed by the Sarcoptic
infestation as they may stop grazing which can lead to a rapid fall in milk production, and
deterioration of health condition. With the increase in the irritation due to scabies, the camel
rubs, bites and scratches the affected areas in an attempt to reduce the itchiness. Due to rubbing,
biting or scratching, the mites move to the periphery affecting the healthy tissues and resultantly
affected area spreads. As the disease prolongs, the skin becomes excoriated, leading to hair loss
and the development of scabs. These scabs in turn may be rubbed away and a red surface
developed. The animal becomes restless due to severe Sarcoptic mange infestation and
involvement of most of the body surface. If the diseased animal is not treated in time, the animal
loses its health condition, become emaciated and within two, three weeks the acute stage of

disease may give way to more chronic state (Gorakh et al. 2000, Abubakar et al. 2002, Driot et
al. 2011). Sarcoptic mites rarely survive long off the host under natural conditions.
A continuous direct contact of animal keepers with their camels can also lead to
transmission of diseased condition in human beings which is termed as pseudo scabies.
Transmission of infection from camel to man usually takes place during milking, handling or
riding. The main symptoms of pseudo scabies can therefore be seen in the inter digital spaces of
the hands, on the wrists, forearms, the elbows, the axillary folds and inner side of the thighs.
Once a herd is infected with Sarcoptic mange, continuous reinfection of the disease occurs
(Schillinger 1987, Singh & Veer 2005, Premalatha et al. 2010).
Sarcoptic mange is usually considered to be a seasonal disease and is often reported
severe during the winter months as in cold weather the disease had an acute course. However,
there is some evidence that in some countries hot weather predisposes to acute outbreaks of
camel mange and in the cooler, winter season the rate of mange infestations are at the lowest. In
the summer the activity of the mite seems to decline or disease becomes chronic. Dietary intake
is an important factor in mange infestation. Nomadic camels on a low nutrition plan, probably
carrying heavy worm burdens in hot desert conditions are likely, therefore, to be highly prone to
Sarcoptes at this time (Dinka et al, 2010). During such periods of great activity, the mites are
readily transmissible from one animal to other animals (Richards, 1987, Banaja & Ghandour,
1994, Tefera & Gebreah, 2001).
Mange can easily be diagnosed clinically from the occurrence of pruritus, depilation,
alopecia, thickened skin, folds around the joints and encrusted plaques being the main
characteristics of this parasitosis. In order to control this zoonotic disease, it is essential to treat

both camel and man along with effective checks over other predisposing factors of the disease
such as hygiene and nutritional requirements of the animals.
The skin diseases like the scabies both in human beings and animals are being treated
with a variety of allopathic drugs now a day, but the role of herbal plants in use since centuries in
different shapes cannot be ignored at all, especially in the rural lifestyle. Further with the
continuous use of different acaricidal drugs, the issue of resistance development has come across
as a challenge for the researchers to find some alternatives for the purpose. Accordingly the
research work on the use of traditional herbal medicines is gaining attention day by day.
Although there are many reports and studies regarding the prevalence of Sarcoptic mange
in camel from different parts of the world, only few preliminary reports are available for Pakistan
and none of them provide detailed epidemiology of Sarcoptic mange and its effect on host
health. Therefore, keeping in view the importance of the mange problem in camel population of
the country, the present project was designed to determine the prevalence of Sarcoptic mange
infestation, factors in its occurrence its zoonotic importance, effect on blood physiology and
different treatment options in the camel population of Punjab, province in Pakistan. Availability: Items available for loan: UVAS Library [Call number: 2190,T] (1).

by Farooq Riaz (2008-VA-231) | Dr. Muhammad Imran Rashid | Prof. Dr. Kamran Ashraf | Dr. Jawad Nazir.

Publisher: 2015Dissertation note: Toxoplasma gondii is an obligate intracellular protozoan parasite which comes under the classification of phylum Apicomplexa, subclass Coccidiasina (Cornelissen et al. 1984). Toxoplasmosis is one of the more common parasitic zoonoses world-wide caused by Toxoplasma gondii which is a facultatively heteroxenous, polyxenous protozoon that has developed several potential routes of transmission within and between different host species (Tenter et al. 2000). It is the most important source of toxoplasmosis in humans and animals, with cat as definite host and warm-blooded animals as intermediate host (Frenkel et al. 1970). It was first described by Nicolle, Manceaux and Splendore in 1908 from rodents Ctenodactylus gondii (Black and Boothroyd 2000).
Toxoplasmosis is a worldwide parasitic disease and it is estimated that about one-third total population of the world is seropositive for Toxoplasma gondii (Tenter et al. 2000). Prevalence of infection varies between countries, geographical areas and ethnic groups living within a specific region. In Humans, infection rates range from 50% to 83% in Brazil (Tenter et al. 2000; Dubey et al. 2012). Seropositivity of Toxoplasma gondii in China is about 8% with continuously increase while in USA its 10-15%, 50-70% in France and 20% in UK (Dubey and Jones 2008; Zhou et al. 2008; Jones et al. 2009). Prevalence of toxoplasmosis is higher in males (79%) as compared to females (63.4%) and the age dependent sero-prevalence reaches >92% in age group of 40 to 50 (Coêlho et al. 2003).
Transmission occurs through the ingestion of contaminated vegetable /water with oocysts, as well as the ingestion of contaminated raw/undercooked meat with tissue cysts (Gajadhar et al. 2006). Transmission may also occurs by ingestion of sporulated oocysts, or bradyzoites within cysts present in the tissues of numerous food animals (Esteban-Redondo et al. 1999). In humans, transmission of Toxoplasma gondii happens mainly by eating raw or undercooked contaminated meat, raw cow’s milk and birds eggs, swallowing oocysts dis-charged in feces of infected cats, inoculation of trophozoites through the skin, or by inhalation (Wallace 1971; Wallace 1973; Bannister 1982).
In humans, mostly infections (congenitally or post-natally acquired) are asymptomatic. Congenital infection occurs only when a woman becomes infected during pregnancy. Congenital infections acquired during the first trimester are more severe than those acquired in the second and third trimester (Desmonts and Couvreur 1974). The main clinical signs associated with toxoplasmosis are anorexia, weight loss, lethargy, dyspnea, ocular signs, pyrexia, vomiting and diarrhea, jaundice, myositis, encephalitis and abortion. Humans become infected when they ingest the toxoplasma at infective stages (oocysts and tissue cysts) found in some cat feces and in raw meats.
In addition to being hazardous to livestock animals, the T. gondii infection is also important due to its zoonotic implications (Jittapalapong et al. 2005). Congenital abnormalities in humans, such as microcephaly, hydrocephaly, chorioretinitis, convulsion, cerebral calcification, epilepsy, blindness, deafness, and mental retardation may occur if the mother acquires infection during pregnancy (Jones et al. 2003). In addition to congenital anomalies, T. gondii also causes severe neuropathologic infections in immuno-compromised hosts, such as AIDS and cancer patients receiving chemotherapy (Del Valle and Piña-Oviedo 2005).
Seroprevalence studies of T. gondii among domestic animals in South-Western Pakistan has indicated considerable prevalence (25% in cattle, 2.5% sheep) (Zaki 1995) and suggesting potential transmission to the human community. Small scale study in urban area of Rahim Yar Khan (Punjab), Pakistan has revealed that the overall prevalence of toxoplasmosis in food animals is 19% (Ramzan et al. 2009). Another study has already been published that untreated patients with leprosy in Pakistan have shown significant seroprevalence (29.6%) of antibodies against T. gondii (Hussain et al. 1992).
Vaccine against toxoplasmosis is not available yet with one exception (“Toxovax” for sheep). Vaccine against T. gondii in animals used for human consumption may block the possible transmission to humans (Bhopale 2003). SAG1, among one of the major antigenic components of Toxoplasma gondii is a major surface antigen identified on the surface membrane of this parasite using a monoclonal antibody (Handman et al. 1980). SAG1 is an important surface antigen, expressed by tachyzoite form of T. gondii and is a putative candidate for vaccine and diagnostic against toxoplasmosis (Sharma et al. 1983; Godard et al. 1990). Immunization with SAG1 adjuvanted with saponin Quil A or incorporated in lysosomes provided total protection after challenge (Bülow and Boothroyd 1991; Khan et al. 1991). SAG1 is single copy gene with no introns (Burg et al. 1988), regulates both humoral as well as cellular Th1 immune responses (Liu et al. 2008) and is powerful candidate for vaccine against toxoplasmosis. SAG1 is a potent candidate of diagnostics for detection of serum antibodies against toxoplasmosis in Man and animals (Abu-Zeid 2002).

Molecular Diagnosis Of Trypanosomiasis In Pet Dogs Of Lahore
by Muhammad Asif (2007-VA-460) | Prof. Dr. Kamran Ashraf | Dr. Nisar Ahmad | Dr. Jawad Nazir.

Publisher: 2015Dissertation note: Trypanosomaevansiis a protozoa that causes surrain a wide variety of mammals. It is widely reported in adult dogs (Rashid et al. 2008; Defontis et al. 2012). Trypanosoma evansiis utmostcommonlyexisting trypanosome in animals. It is a salivarian pathogen (Hoare. 1972). Stomoxyand Tabanidssppare menifested as mainvectors universally. Oral spreadis also reported in both wild and domestic animals (Adams and Lionnet. 1983). Since 2008, surra became obligatory not only in horses, because it has been considered as a multi-species disease by the OIE (OIE. 2008; Salim et al. 2011). Surra usually follows an acute course of infection in dogs, though it is sporadically prevalent (Ravindran et al. 2008). Outbreaks of canine trypanosomiasis have been reported in India, Iran,Brazil, and South America (Herrera et al. 2004; Morteza et al. 2007; Umezawa et al. 2009). Trypanosomaevansionly has been reported from subcontinent (Ravindran et al. 2008).
Causative agent for American trypanosomiasis is Trypanosoma cruzi (T. cruzi) and African trypanosomiasis (surra or sleeping sickness) whose causative agent isTrypanosomaevansi(T.evansi).These are two forms of canine trypanosomiasis.It was originally an enzootic disease mingling in mammals and birds, which served as areservoir. The disease became zoonotic due to interaction between rural populations and natural foci, which are the results of biologicalinequity (Johns et al. 2000). Peracute to acute infections due to trypanosome result in high temperature, hemorrhages in the mucosal and serosal sides. Anemic condition of the patient is produced due to loss of RBCsfrom circulationby the mononuclear phagocytic system which is the cardinal feature of trypanosome infection.In chronic infections, anemia may be resolved due to little parasitic load in blood at capricious degrees. (Urquhart et al. 2002).
Some note able signs may compriseedema of throat and head, Blindness due corneal opacity, Temperature and anorexia. Larynx may alter the voice of the dog due edema, which can complicate with rabies. Infected dogs are considered as a risk factor in household spread of the Chagas disease in humans (Cohen and Gurtler.2001).
In native animals, dogs have the flankingassociation with humans; they may assumedconsiderable epidemiological importance in the perspective of public health and zoonosis. In humans,T.evansiproduce chronic pathological changes, which includes congestive cardiac insufficiency, finding of which isproblematic and can be unexploited due to multisystemic nature of the infection; it increases the need for epidemiological and experimental support. Moreover, causative agent of trypanosomiasis must beconfirmed by laboratory analysis, which can make availablesignificantprovisionwhen using suitable techniques, suitable reagents, and subsequent good laboratory practices (Eloy & Lucheis. 2009).
There has been development of several compounds with value against canine trypanosomiasis, however none of these products have been produced in a large commercial scale or even accessible in the market. The apparent inaccessibility of new trypanocides in the market have continued a great challenge to the treatment of the infection. Diminazine aceturate dose of 3.5 mg/kg in T.congolense infection; 7 mg/kg inT. brucei andT. evansi(Aquinos. 2007) has shown efficacy when used to treat canine trypanosomiasis.However, treatment does not provide satisfactoryresults but only sustained the life of the dog for some reasonable period (Amora. 2004).
Dogs were vaccinated with a fixed T.rangeli against canine trypanosomiasis recently (Basso et al. 2007). Experimental infections of the vaccinated dog produced disease of low parasitaemia apparently from vaccine induced immunity. Furthermore, feeding of the vaccinated dogs with the nymph stage of triatomine reduced the rate of infection in the bugs. Since dogs are the reservoir of Chagas disease in man, advances in this area could reduce the rate of infection of kissing bug which will in turn aid in the control of the disease in man (Basso et al. 2007) are necessary to establish the diagnosis.Sensitivity of direct parasitological examination is directly related to parasitic burden, biological material.
The diagnosis oftrypanosomiasis is based on combination of comprehensive clinical inspection, appropriate sample collection, sample size, suitable diagnostic tests and suitable conduction of tests and logical interpretation of results. In canine trypanosomiasis where disease prevalence is great, some tests of low diagnostic sensitivity may suffice (OIE. 2008). Parasitological diagnosis could be made by microscopic inspection either of blood, lymph node or CSF of infected dogs (François et al. 2005).
Pet dogs have been the companion of human being since ages, and shares the environment and belongings. Trypanosoma is found in dogs causing health problems effecting their routine activities. Rapid and accurate diagnosis of the infection is must to do for better therapeutic approach and early recovery of the animal. PCR is gold standard test for the molecular diagnosis of disease leading to quick diagnosis, early recovery and cost saving. So, regarding to disease importance and dogs domestications which is increasing day by day in and around Lahore area, we have focused this species to determine the Trypanosoma evansistatus in dogs in this area. This whole study is based on two diagnostic techniques i.e. screening through microscopic examination and confirmation of these samples via PCR with details regarding age, sex and breed association with the disease.

Publisher: 2015Dissertation note: Tick infestation and the resulting transmission of serious pathogens in ruminants is one of the most important problems of the livestock industry in developing countries (Aktas et al. 2012).Bovine babesiosis is economically the most important tick-borne disease of cattle worldwide including areas of Australia, Africa, South and Central America. Babesia species are protozoan parasites that parasitize the erythrocytes of domestic animals and humans, causing Anemia in the host affected. Polymerase chain reaction (PCR), which is more sensitive and specific technique, offers an alternative approach for the diagnosis of Babesiosis (Zulfiqar et al. 2012).
Geo-climatic condition of Punjab, Pakistan favours the multiplication and survival of ticks which play a major role in the biological transmission of Tick Born Diseases. In earlier reports the prevalence of cattle tick infestation was more than 50% from Punjab (Durrani et al. 2008, Sajid et al. 2009).
Keeping in views the importance of the disease, the present study was carried out to determine the prevalence of Babesiosis in cattle of Lahore, District of the Punjab, Pakistan. A total of sixty (60) blood samples was collected randomly from dairy cattle of District Lahore. These samples were transported to the Laboratory of Parasitology, Department, University of Veterinary & Animal Sciences, Lahore and were kept at 4oc until further processing for Microscopic examination (Zakir et al. 2014) and then for PCR. We focused on the early detection of Babesiosis through Microscopic examination of Blood samples. For further confirmation of Babesiosis, the blood samples were processed through Polymerase Chain Reaction (PCR) as described by Zulfiqar et al. 2012.

Staining was performed using Giemsa Stain as method followed by Zakir et al. 2014 i.e. the glass slides bearing thick and thin blood smears were stained with one fourth of dilution of commercially available Giemsa stain for four minutes and were observed under oil immersion at 100X objective to detect the presence of Babesiosis.
All the blood samples were examined through Microscopy showing 04 positive ones, then all the samples were processed using PCR for final confirmation of Babesiosis in Cattle. PCR was performed under the conditions as previously described by Zulfiqar et al. 2012. PCR reaction was performed to obtain amplified products over 30 cycles by 94ºC for 5 min., 94ºC for 30 sec., 50ºC for 30 sec., 72ºC for 45 sec. and completed with a final extension step of 7 min. at 72ºC. Finally the amplified DNA fragments were analyzed after electrophoresis on 1.5% agarose gel.

Publisher: 2016Dissertation note: Intestinal parasitic infections are extensively spread globally and most affected population is children. In primary schools environments children are confirmed as a most susceptible for acquiring Intestinal parasites(IP) through nails.
Intestinal parasites were more prevalent in fingernails of children of primary schools in District Lahore.
A total of 300 nail samples were collected from the fingernails of the school children of different age and sex. The nails were swabbed into a clean sterile container containing normal saline. Finger nail clippings were collected from both hands of each subject using sterile nail clippers and were placed in labeled containers containing normal saline. Samples were examined by direct microscopy using Lugol’s iodine and Eosin preparations. Sediments from the nail clippings were examined after digestion with 10% Potassium hydroxide and centrifugation at 2500rpm for 5minutes.The parasites were isolated from the fingernails of the primary school children of both sexes and prevalence was recorded.
The collected data was analyzed using SPSS version 20. The prevalence of parasites was presented as descriptive statistics, while the relationship between several variables (age, gender,educational level) and presence of parasites was determined by the chi-square test. The level of significance used was P<0.05.
This study will help to create awareness among society especially school children about parasites and parasitic infections. It will also help to improve health level of school children, education and environment of schools and will develop the habit of keeping hygiene and handwashing
practice in children as a result of which a healthy study competition will be developed among school children.

Publisher: 2016Dissertation note: Dogs and cats are kept as pet animals in and around Lahore area. Along with other problems, parasitic problems are common in these animals. Isospora felis and Isospora rivolta are the most commonly seen parasites in cats in many parts of the world. No data existed about its prevalence, possible risk factors and therapeutic control of Isospora infection in cats in Lahore, Pakistan. Hence the present study was aimed to assess the associated risk factors, prevalence and best therapeutic remedy for Isospora infection. A total 100 faecal samples were collected from Tollinton market, pet clinics of Lahore and pet center of University of Veterinary and Animal Science, Lahore. Epidemiological parameters taken into consideration included sex (Male n=61, Female n=39), breed (Persian n=54, Siamese n=18, Himalayan n=16 and local or cross bred n=12), age (kittens n=21, adults n=79), environment (captive n=60, household n=40). Samples were examined by using direct smear technique. Species of Isospora were differentiated on the basis of their size by micrometry and by oocyst shape. Oocysts were counted by Mc-Master counting technique. Oocysts were counted on day of sample collection and day 10 post treatment. Positive samples were subjected to two chemotherapeutic agents; Amprolium and Furazolidone. Chi square test was applied to assess the prevalence and its relation with other risk factors was applied on pre-treatment and post treatment oocysts reduction count. Higher (P < 0.05) prevalence of Isospora was found in cats from captive system (65%) as compared to cats from household (10%) system. Persian breed was found to be more prone (42.59%) to the infections with Isospora species. Age group was not associated as a risk factor. Positive cats were divided into 2 groups for therapeutic trials. Group I (n=16) was treated with Amprolium 150 mg/kg/day for 5 days while group II (n=16) with Furazolidone 20 mg/kg/day for 5 days. Amprolium reduced the oocysts by 100% while Furazolidone causes 87.5% reduction of oocysts.
41
So it can be concluded from the present study that Isospora is highly prevalent in Lahore area and Amprolium is better chemotherapeutic agent for the treatment of coccidiosis in cats than Furazolidone. Availability: Items available for loan: UVAS Library [Call number: 2541-T] (1).

Publisher: 2016Dissertation note: Parasites are a major cause of disease and production losses in livestock, frequently causing major economic loss and impacting on animal health. In livestock roundworms are deliberated the important economically upsetting internal parasites. Although buffalo can be diseased with tapeworms and flat worms, their effect on animal performance is minimal compared to the round worms. Buffalo feed on dry concentrate are less infected with parasite as compared to those who fed on pastures. The timing and frequency of anthelmintic treatments under such climatic conditions will vary greatly from place to place. Humid climates are permanently favorable for the development of infective larvae. With the frequently use of one or more dewormer animal produces anthelmintic resistance also its cost a lot for large herds. Herbal medicine is better option for control of intestinal worms. Herbal drugs are cheap, easy available and easy in administration.
The present study was designed to
1. Check the prevalence of intestinal nematodes in the buffalo population.
2. To determine the efficacy of herbal drugs against intestinal Nematodes in buffalo calves
3. To evaluate the comparison of effectiveness between herbal and commercial drugs to control the intestinal Nematodiosis in buffalo calves.
One hundred buffalo’s faecal samples were examined to check intestinal nematodes prevalence. All buffaloes belonging to various breeds were examined. 56 (93.33%) were Mix breed, 13 (72.22%) Nili Ravi breed and 18 (81.82%) of Kundi breed were positive for intestinal nematodiosis. 47
SUMMARY
Among the examined (87 %) buffaloes were found positive for nematodiosis. Ten buffaloes found positive (10 %) were less than 12 months, 25 buffaloes were between 1-2 year, 39% buffaloes were between 2 - 4 year and 13 buffaloes were above 4 years old were found positive for intestinal nematodiosis.
Among these buffaloes, 65 were male and 35 females. Out of male buffaloes 55 were found positive. While among 35 females 32 were positive for intestinal nematodes.
A total of 30 infected buffalo calves, of various ages (8-12 months), both sexes average body weight of 100 kg and naturally infected with intestinal nematodiosis were used for anthelmintic trials. These were randomly divided into 3 groups i.e. A, B, and C each having 10 calves. Group A and B were treated with herbal medicine. Group A was treated with dried powder Nigella Sativa (Kalonji) seeds at dose level of 250 mg/kg body weight. Group B was treated with Citrullus colocynthis (Kor Tumbha) fruit dried powder at dose level of 250 mg/kg body weight, group C was treated with Albandazole at dose level of 7.5 mg / kg body weight. The sample were taken on 0 day, 7th day, 14th, 21st and 28th day and EPG was determined by modified McMaster technique.
Statistical analysis was done using the statistical package for social science, (SPSS) version 20 (Chicago IL, USA). Data was presented as (mean+ S.D), the group descriptive measures were compared by CR Design (Anova) and applying differences were considered significant at P < 0.05. Post hoc test using Duncan multiple range test, to check the pair wise differences and alpha M. There was highly significant difference between commercial and herbal drugs. There was small significant difference between herbal drugs Nigella sativa and Citrullus 48
SUMMARY
colocynthis, both were highly effective against intestinal nematodiosis but less effective than Albandazole.
It is observed Nigella sativa dose showed a significant reduction in EPG .p value is p > .2284 at o day and at 7th day P>0.0146 ,at 14th day p> .0029 . There was also a significant decrease in EPG by Citrullus colocynthis but when compared these herbal drugs with commercial drugs the efficacy of herbal drug is 100 % at 21st day.
Recommendation.
Both herbal drugs Nigella sativa and Citrullus colocynthis used in trial were found highly effective against intestinal nematodiosis in buffalo calves but less effective than synthetic drug Albandazole hence, these herbal drugs cannot be recommended to be used as routine deworming of animals at farm level.
Keeping in view effectiveness of these herbal drugs in early age and having no side effects, it is recommended to be administered as feed additive to enhance immune-potentiation, effective anthelmintic and liver tonic.
There is dire need to carry out more research with increased dose rate of these herbal drugs and also use in combination with other herbal as well as synthetic drugs to evaluate its synergistic effect so farmer can be benefited of its maximum potential.

Publisher: 2016Dissertation note: Estimated population of sheep in Pakistan is 27.8 million. Balochistan is the largest province which comprises 44 percent of the total area of Pakistan and only 4.9% of entire population of the country. Share of Livestock in Agriculture is 55%, 11.4% of National GDP of Pakistan and more than 47% in the economy of Balochistan. In between the Chelicerates, (mites and ticks) characterize the biggest and most wide taxon, with a valued 0.5–1 million species. More then 48,000 species defined (Halliday et al., 2000). Mange is a contagious disease showing signs like crusty, dermatitis and loss of hairs. Almost 50 mites species having 16 families and 26 genera responsible for mange where all the main mite species having the orders of Astigmata and Prostigmata. Bolan district is situated in the center of Balochistan province of Pakistan Population estimate 640,000 (2005). Bolan district is administratively subdivided into six tehsils viz Bhag, Dhadar, Machh, Sani, Khattan. The present study was carried out in tehsil Bhag. Latitude 29.0415, longitude 67.8239, Altitude 88 meters above the sea level. 1442 square kilometer of Tehsil Bhag. Mean rainfall is 209.9 mm, range of temperature (Avg) is between 40.6°C and 14.58°C. Four distinct breeds of sheep found in Balochistan are Balochi, Bibrik, Harnai, Rakhshani.
A total of 200 sheep were randomly selected to study the prevalence of mites’ infestation. Skin scraping technique was used. For chemotherapy 30 sheep positive for mange mites through skin scraping test were randomly selected and divided into 3 groups of viz A, B, C. Each group contain 10 number of sheep. Sheep’s in group A were injected Ivermectin at 0.2mg/kg bwt subcut while the animals in group B, were treated with Trichloroforn in the form of 0.15% solution as topical application. The members in group C were treated topicaly with aqueous

Publisher: 2016Dissertation note: The main area of research in this study was to assess the prevalence, hematological aspects
of Bovine nematodiasis. Three main experiments were conducted to highlight the objectives of
the present research study.
The first experiment was conducted to find out the prevalence of large ruminants major
nematodes for one year. For this purpose buffalo and cattle of either sexes and between < 1 year
to > 2 years of age were selected from two sites i.e., Quetta and Qilla Abdullah. Fecal analysis of
these cattle and buffalo showed overall higher (33.99%) nematodes prevalence recorded in buffalo
in Quetta, (27.99%) in cattle at Qilla Abdullah followed by in cattle at Quetta (26.66%). Five
nematode infection was recorded in all two experimental sites with higher prevalence of
Haemonchus contortus in buffalo at Quetta and Ostertgia ostertagi in cattle at Quetta and Qilla
Abdullah. The buffalo and cattle of < 1 year presented higher nematodes prevalence than 1-2 years
and > 2 years. The female buffalo and cattle were infected with nematodes prevalence higher
than male animals. These five nematodes were prevalent almost throughout the year, however a
peak infection was recorded during August and September in cattle and October in buffalo. The
high temperature, rainfall and humidity during these months may be predisposing factor of higher
prevalence. Mostly the level of nematodes infection was low(< 800 EPG) and did not seriously
impaired the buffalo and cattle productivity.
Second experiment on assessing the comparative efficacy of anthelmintics (Levamisole,
Oxafendazole and Ivermectin) against cattle and buffalo nematodes were conducted at Govt and
private farms. The results showed that Ivermectin than Oxfendazole were found effective against
cattle and buffalo nematodes. The higher (89-100%) reduction of EPG were recorded in cattle and
87
buffalo calves treated with Ivermectin followed by Oxfendazole (86-100%), Levmisole (88-
100%).
Third experiment was conducted to determine the hematological values in healthy and
nematodes infected animals. Different hematological parameters i.e., TEC, TLC, Hb estimation,
were determined. The results showed that overall low Hemoglobin estimation and RBC were
recorded in nematodes infected animals than healthy, while higher WBC were recorded in
nematodes infected animals than healthy. The Lymphocytes and Neutrophil and Monocytes were
higher in some nematodes and lower in other, while higher mean Eosinophil counts was recorded
in all nematodes infected animals than healthy animals. Availability: Items available for loan: UVAS Library [Call number: 2730-T] (1).

Anthelmintic Activity Of Ginger Against Gastrointestinal Nematodes In Goats
by Muhammad Shahid (2008-VA-127) | Dr. Haroon Akbar | Prof. Dr. Kamran Ashraf | Dr. Muhammad Avais.
Material type: ; Literary form:

Publisher: 2016Dissertation note: Gastrointestinal tract nematodes are responsible for wide range of health problems,
economic losses in goats and are characterized by impaired milk production, meat process,
decreased fertility, low kidding rates, decreased working efficiency and even death of the goats.
Gastrointestinal tract nematodes cause economic losses via morbidity and negative effects on
feed intake, nutrient utilization efficacy and also reduce young animal’s growth rate as a result,
leading to decreased productivity and performance of the infected animal. Due to such economic
losses, the control of the helminths is unavoidable which is also possible by herbal products such
as Ginger. Ginger has pharmacological and gastrointestinal prokinetic activities to cure
constipation, indigestion, vomiting, infectious diseases and helminthiasis. In the current study,
anthelmintic activity of Ginger has been tested against gastrointestinal nematodes of goats.
For therapeutic trials, a total of 75 goats positive for nematodes having EPG >150 were
selected randomly and divided into three groups named as Group A, B and C, each group
comprising of 25 animals. The goats of Group A were orally treated with crude powder of ginger
(Zingiber officinale) @ 3 gram/kg body weight, orally. Goats in group B served as positive
control (infected and treated with Oxfendazole). Group C comprised of positive animals which
were not treated during whole the experiment. The fecal samples were collected at day 14 (Posttreatment).
Drug’s efficacy was assessed on the Fecal Egg Count Reduction Test (FECRT) and
was calculated by following formula (Traversa et al. 2007).
[((Pre-treatment EPG – Post-treatment EPG)) / Pre-treatment EPG] × 100
SUMMARY
34
Data regarding therapeutic trails were analyzed by repeated measures one-way ANOVA, using
SPSS version 20.0, p< 0.05 was considered as significant. Trial was analyzed under different
parameters.
Ginger has shown good anthelmintic activity against gastrointestinal nematodes in goats
as evident from 63% reduction in EPG. It is suggested hereby to conduct a dose trial for the use
of ginger against nematodes in goats by using different dose levels including at least 5 different
groups of dosages like 3gram; 3.5grams; 4grams; 4.5grams and 5grams per Kg body weight. The
current study has highlighted the anthelmintic activity of ginger (Zingiber officinale) against
gastrointestinal nematodes in goats. More trials using this herbal product in other animals will
further highlight the importance of using this commonly-available and economical herbal
product in the control of gastrointestinal nematodes in livestock. Availability: Items available for loan: UVAS Library [Call number: 2712-T] (1).

Acaricide Resistance Of Tick Population Infesting Buffaloes In District Narowal
by Muhammad Mubashar Abdullah (2015-VA-1104) | Prof. Dr. Kamran Ashraf.
Material type: ; Literary form:

Publisher: 2017Dissertation note: Tick imperviousness to acaricides is an expanding issue in Pakistan and represents a genuine financial danger to the domesticated animals and veterinary pharmaceutical enterprises. New acaricides are to a great degree costly to grow so the present acaricides ought to be viewed as a constantly decreasing asset, which ought to be ensured by all methods conceivable. The principle goal of the review was to distinguish the stages of tick imperviousness to acaricides at close business and collective ranges in District Narowal, Pakistan. Likewise to contrast the in vivo techniques and with explore acaricide administration procedures which may build the life expectancy by utilized acaricides.
To meet these points a field survey (February 2016 to March 2017) was carried out at 3 tehsils (Tehsil Narowal, Shakargharand Zafarwal cities of Pakistan to monitor levels of field tick resistance to acaricides. The larvae were originally obtained from engorged female A.hebraeum, Hyalloma, Boophilus, Dermacentor, Ixodes, R. appendiculatusand R. evertsievertsi. The larvaewere tested against different concentrations of trichlorofon, ivermectin and cypermethrin using the Shaw Larval Immersion Test (SLIT). Mortality dose data were subjected to probit analysis using a BMDP statistical package. Factors of resistance (FOR) were calculated by comparing the larval response of ticks from the field.
On the communal farms high levels of tick resistance were detected to cypermethrin as well as partial resistance to ivermectin whilst no resistance was detected against trichlorofon. On the commercial farms, however, ticks were equally resistant to trichlorofon, cypermethrin and ivermectin. The populations of Hyalloma, Boophilus, Dermacentor, Ixodes, on these farms had developed higher levels of resistance to the testacaricides than the equivalent R. evertsievertsi, R. appendiculatus and A.hebraeumpopulations. Higher levels of tick resistance to trichlorofonwas observed on3 tehsils (Tehsil Narowal, Shakarghar and Zafarwal)than on communal farms, however, there was no significant differences in tick resistance to ivermectin and cypermethrin at both the commercial and communal farms. It was surmised that inappropriate use of acaricides might have resulted in higher tick resistance to the currently available acaricides on the commercial as well as the communal farms. Correct acaricide usage may solve this problem to a limited extent.
Comparative in vivo tests were also carried out on the larvae and adults of Hyalloma, Boophilus, Dermacentor, Ixodes, to determine the susceptibility of this tick to different concentrationsof the currently used acaricides, (amitraz, ivermectin and cypermethrin) at three commercial dairy farms, (“Brycedale”, “Sunny Grove” and “Welgevind”) in the areas of District Narowal, Pakistan. Resistance of field strains of Hyalloma, Boophilus, Dermacentor, Ixodes, Dermacentor,were determined using the Adult Immersion Test (AIT) as the latter test took into account factors such as oviposition assessment and reproductive ability. At “Brycedale”, resistance to trichlorofon and ivermectin was detected with the AIT method. Emerging resistance to trichlorofon and resistance to ivermectin were also detected . At “Sunny Grove” resistance was detected to cypermethrin and at “Welgevind” resistance was detected to ivermectin with the SLIT whilst no resistance was detected using AIT. It would appear that the Hyalloma, Boophilus, Dermacentor, Ixodes, populations tested on these dairy farms were more resistant toivermectin than to trichlorofon or cypermethrin.
Nearly 50% of the dairy farms sampled showed resistance to ivermectin and the majority had susceptible Hyalloma, Boophilus, Dermacentor, Ixodes, populations to both amitraz and cypermethrin. In general there was a good correlation between the Cypermethrin and Trichlorofon whilst in many cases there was poor correlation between the Cypermethrin and Ivermectin.
From this study it would appear that the In vivo method was a reliable to detect resistance within seven days. In vitro method the ELT and the RET could possibly be used as screening methods to detect acaricide resistance on farms whilst the SLIT would remain the test of choice for National surveys. In addition the ELT is less costly and does not require sophisticated equipment for field testing if resistance development compared with other in vitro test methods. This method, however, still needs to be validated and standardized for use in Narowaland the rest of punjab where tick control is important.
