Publisher: 2014Dissertation note: Livestock is one of the major sectors of Pakistan’s agrarian based economy. During 2013-14, it contributed almost 55.4% to the agricultural value added and 11.9% to national GDP. In the livestock sector, gross value addition increased from Rs.735 billion to Rs.756 billion; revealing an increase of 2.9% as compared to the previous year. Livestock is considered the best tool for poverty alleviation, as most of the livestock are owned by poor people who live in the rural areas. Pakistan is 4th largest Milk producing country in the World. Its Cattle Population is 33 Million while Buffalo Population is about 30 Million (Economic Survey of Pakistan, 2013-14). Despite large population, per animal production is very low.The low productivity of these animals is because of poor quality feed stuff. Their productivity can be enhanced by feeding them balanced ration.
Growing human population urges the intense need to explore the present livestock resources to fulfill the animal protein requirements. It is impossible unless optimal fodder and forage production is ensured. In Pakistan, low quality fodders coupled with the reduction in the fodder area are the main constraints, which adversely affect the animal production. In future, it is expected that ruminants will be more dependent on forages because readily expanding human population will have direct competition with livestock for edible grains.
Among the problems facing the livestock in the tropics is the low protein tropical grasses and the high cost of alternate sources of protein such as the Soybean and other oil cake. A portion of nitrogen in feeds for ruminants may be provided in the form of simple nitrogen compounds (or0non-protein0nitrogen0NPN) 0that are degraded in the0rumen to release ammonia (NH3), which is used by rumen microorganisms to produce amino acids. The amount of NPN that can be provided is limited. The product which is the urea, when it releases NH3 faster than it can be converted into microbial protein excess NH3is absorbed through the rumen wall, causing toxication.
Protein is often0the0major0limiting0nutrient for ruminants. Protein-rich leguminous forages and vegetable protein supplements are usually expensive or not available.The manufacture0of0urea and0ammonia for use as0fertilizer has been greatly0expanded in0many countries, 0but these compounds0could0not be0used more0widely in feeds for0ruminants. The ability0of0the0micro-organisms0in0the0rumen0of0cattle0and0sheep0to0utilize0urea0sources0to form0true protein0that0can0be converted0to meat0and0milk0by the0animals, represents0an important0contribution0to0man's0food0supply.0Maximizing0microbial0protein0synthesis0and flow0to0the0duodenum0by0reducing the0recycling of0microbial N in the rumen offers a potential0to improve0the production0efficiency0of ruminants.In general, the efficiency of utilization of dietary N by cattle is relatively low under normal production conditions (Castillo et al, 2001) with a global average N-efficiency in cattle estimated at 7.7 % (Van der Hoek, 1998). Urea is used rather inefficiently for production of protein products (Broderick et al, 2009) and due to its wide use in ruminant feeds, may0be0partially0responsible for0the poor N efficiency0in cattle. Low efficiency of utilization of dietary urea has been attributed to the rapid0hydrolysis0to0ammonia (NH3) in0the0rumen0by microbial0enzymes which occurs at a higher rate than its utilization byrumen bacteria, leading to ruminal accumulation and absorption0of0ammonia andsubsequent excretion of0urea in the urine (Golombeski0et0al., 2006; Highstreet0et0al,2010).Furthermore if used above threshold level, the main problem with urea usage is that it can cause toxicity and even death of the animals. Farmers hesitate to use urea as a source of protein, resulting which his animals remain underfed and never achieve the peak production.
Urea0poisoning0is0one0of0the0more0commonly0suspected0toxicities0of0cattle. Urea0is0used as0a source0of non-protein0nitrogen0in feed0supplements.In ruminants,0nitrogen0from0urea is released0in the0rumen as0ammonia0and0can0be0used0by0rumen0micro0flora0to0synthesize protein. This0protein0thenbecomesavailable0to0the0animal0through0the0normal0processes of digestion0and0absorption. However,if0 more0ureaisconsumed0than the rumen organisms can0metabolize, the0ammonia0is0absorbed0from0the0rumen0into0the0blood.Ruminal pHbecame alkaline due to the hydrolysis of urea to0ammonia (Buffalo Bulletin,2002). The ammoniaisthen0converted0back0to urea in0the liver and is0the0excreted by0the0kidneys. This0pathwaycan easily be0overwhelmed,0when excess0ammonia0and urea0circulate0in the blood,0causing0poisoning. Poisoningcanoccur0rapidly0from a few0minutes0to four0hours after0consumption. Suspect0urea0poisoning0if cattle are found0dead close to0the0supplement (H. Parkes et al. 2003).Slow release urea has been shown to affect ruminal fermentation characteristics.Most notably, slow release urea is intended to0reduce0the release rate0of NH3 within the0rumen. Most reports on controlled release urea have shown a reduction in ruminal NH3 concentration when measured (Cherdthonget al, 2011; Huntington etal, 2006b; Taylor- Edwards0et0al, 2009d). This is the reason why slow release urea presents a lower risk for ammonia toxicity than feed grade urea. Ruminal NH3 concentration is often related to ruminal pH, as the protonation of NH3 toNH4+ when ammonia from urea ionizes, can result in an increase in ruminalpH. Consequently, there are reports of higher ruminal pH for animals fed urea than those fed slow release urea (Cherdthongetal, 2011; Taylor-Edwards et al, 2009b)

Publisher: 2015Dissertation note: Cryptosporidium parvum is an emerging waterborne zoonotic disease prevalent
throughout the world. There are different strains of cryptosporidium but most important is
C.parvum.It is intestinal protozoon belongs to coccidian family that causes damage to intestinal
epithelium that leads to villous atrophy so decrease absorption sites from intestine. It is not host
specific it can equally infect humans, calves and foals. It is cross transmissible among mammals.
In horses, cryptosporidiosis is most commonly seen in foals (most frequently 1–4 weeks of age)
and is associated with diarrhea and weight loss. Immuno-compromised foals (including foals
with severe combined immunodeficiency syndrome) are particularly at risk. The present study
was conducted in different studs farms in and around Lahore keeping in view the importance of
C.parvum in foals because it is gaining attention as a most important cause of diarrhea in foals so
that effective therapeutic measures should be adopted to control infection. There are 323 samples
are collected among different stud farms and veterinary hospitals and analyzed by using fecal
floatation method and modified Ziehl-neelsen technique. Infection rate of C. parvum in foals in
this study recorded was (12.30%) from different stud farms and veterinary hospitals. Infection
rate (27%) is higher in foals of age group range between 1day to 3 months while the least
infection rate (2.46%) was observed in 9-12 months age group. Infection rate is reciprocal to age
as the age increase infection rate decrease. Infection rate is independent of sex. There is no
relationship between sex and infection rate. Diarrhea is an important risk factor related to
infection rate. In diarrheic foals infection rate is (22.5%) while in case of non-diarrheic foal’s
infection rate is (6.5%) which showed that infection rate in diarrheic foals is three time more as
Summary
36
Compared to non-diarrheic foals. A significantly higher infection rate was observed in those
foals having contact with other animals like rodents, ruminants and dogs. Infection rate (15%)
was observed in those foals having contact with other animals and infection rate (6.5%) observed
in foals having no contact with other animals. Purpose seems to very important in this study.
Game horses have more infection rate which was (15.45%) as compared to draught horses
(4.4%). Game horses have three times more infection as compared to draught horses because
game horses remain in close confinement and foals have more prone to infection. Management is
an important factor infection rate was more in those stud farms having poor management as
compared to those have good management. Infection rate is poorly manage farms was (20.97%)
and (5.5%) in properly manage farms. The results of the comparative efficacy of nitazoxanide,
furazolidone and garlic showed that the Nitazoxanide was the most effective of the three in
treating cryptosporidium infection under field conditions. Efficacy of Nitazoxanide in treating
C.parvum in foals was (88%) during the study followed by furazolidone which have comparative
efficacy of (77%) than garlic with the efficacy of (70%).
In conclusion from above discussion reveals that C. parvum is prevalent in stud
farms in and around Lahore. Associated risk for C. parvum in foals are age less than 6 months,
immune-deficiency, contact with other animals like ruminants and poor management. Infection
rate is more in game horses as compared to draught horses because game horses are manage in
close confinement so the chances of infection are more. Treatment of C.parvum has long course
and effective drug for the treatment of cryptosporidiosis in foals is Nitaoxanide than
furazolidone. Availability: Items available for loan: UVAS Library [Call number: 2300-T] (1).

Publisher: 2015Dissertation note: Strangles is characterized by upper respiratory tract infection, dysponea, anorexia, regional suppurative lymphadenitis causing high morbidity and low mortality in horses as well as in mules and it is an infectious problem of equine. Considering the significance and utilization of equines in our country and the substantial losses rendered by Strangles, the present project was designed to study epidemiology, diagnosis and chemotherapy of strangles in Lahore, Okara and Sargodha districts of the Punjab province in Pakistan. Streptococcus equi subspecies equi is highly prevalent in animals recently recovered from strangles and antibiotics along with immune stimulants and non steroidal anti-inflammatory drug became helpful in the elimination of carrier status of animals for S. equi. Samples were collected from animals recently recovered from Strangles. Samples were collected with the help of sterile cotton swabs dipped in normal saline from nasopharynx & oropharynx followed by culturing of samples on blood agar plates which were incubated anaerobically for a time period of 24-48 hours respectively and S. equi were isolated on the basis of colonies characteristics and growth pattern. Streptococcus equi was confirmed with the help of Gram staining and biochemical tests Catalase reaction, Methylene blue reduction test and Sugar fermentation test. In vitro antibiotic sensitivity test were also performed to select three antibiotics showing best efficacy against S. equi. Carrier animals were subjected to treatment with the help of antibiotic along with combination of immune stimulants and non steroidal anti-inflammatory drug. Carrier status was considered eliminated with disappearance of S. equi from nasopharynx. Blood samples were collected from carrier as well as from healthy animals to check out hematological parameters such as TLC (total leukocytes count), TEC (total erythrocytes count) and MHC (mean hemoglobin concentration) etc. Out of

Comparison Of Two Imported Live Attenuated PPR Vaccines In Local Sheep In Pakistan
by Saliha Saba | Prof. Dr. Aneela Zameer Durrani | Dr. Hassan Salem | Dr. Imran Altaf.
Material type: ; Literary form:

Publisher: 2015Dissertation note: Peste des petits ruminants (PPR) also famous as goat plaque is of viral origin and is extremely contagious disease of sheep and goat (Dhar et al. 2002; Asim et al. 2009). PPR can cause high mortality about 50 – 80 % in non-immunized sheep and goat population. Due to its similarity with other diseases, Peste des petits ruminants (PPR) is being devalued but at the same time it is said to be one of the major constraints to successful small ruminant farming in tropics (Sen et al. 2010). PPR virus is paramyxovirus, enveloped and belongs to the genus morbillivirus. These viruses comprise of 16Kb long, single stranded RNA showing negative polarity (Barrett et al. 2005).
The various vaccines like homologous and recombinant vaccines have been manufactured for the management of Peste des petits ruminants (PPR), as no accurate treatment is available for its control. For the immunity of animals against this disease, the tissue culture based, attenuated rinderpest vaccine (TCRV) had been accustomed over a extensive period because of the antigenic association among RPV and PPRV (Diallo et al. 1989).With the help of fresh freeze-drying methods and stabilizing agents the thermostability of the present PPR homologous vaccine has been enhanced significantly (Worrwall et al. 2001).
In Pakistan, PPR vaccine was manufactured with the help of PPRV Nigerian 75/I (PPR 75/1 LK 6 Vero 75) for the sheep and goat immunization (Asim et al. 2009). India had manufactured numerous live attenuated vaccines like the PPRV Sungri/96 that has been regularized for use (Hegde et al. 2008). ). The Peste des Petits Ruminants (PPRV-Sungri/96 ) vaccine is being manufactured on small and large scale for prevention of Peste des Petits Ruminants (PPR) outbreaks in India (Singh et al. 2004).
Summary
41
The current study was designed to study the immunogenicity of two imported live attenuated PPR vaccines in local sheep. A total of sixty (60) animals were selected and further separated into two groups, viz. Group-A and Group-B, having thirty (30) animals each. Group-A was further sub-divided into A1 comprising 10 sheep to which Raksha PPR vaccine (Sungri 96) was administered, A2 comprising of 10 sheep to which PPR vaccine (Nigeria 75/1) was administered and A3 comprising of 10 non-vaccinated sheep which served as control. Group B was separated into two sub-groups i.e B1 and B2 having fifteen (15) animals each. The Group-B1 was sub-divided into B1a having 05 sheep to which Raksha PPR vaccine (Sungri 96) was only administered, B1b having 05 sheep to which along with Raksha PPR vaccine (Sungri 96), Vitamin AD3E was administered and B1c having 05 unvaccinated sheep which served as control.
Similarly the Group-B2 was sub-divided into B2a having 05 sheep to which PPR vaccine (Nigeria 75/1) was only administered, B2b having 05 sheep to which along with PPR vaccine (Nigeria 75/1), Vitamin AD3E was administered and B2c having 05 non-vaccinated sheep and served as control group respectively. The serum samples were collected and mean antibody titer was calculated by complement fixation test (CFT) at zero day, 7th day, 14th day, 28th day and 48th day post-vaccination.
The live attenuated, Raksha PPR (Sungri 96) vaccine induced the mean antibody titers of 0 ±0.00, 4.7±0.48, 4.7±0.48, 4.9±0.31 and 4.9±0.31 which was significantly higher than the mean antibody titers shown by the PPR (Nigeria 75/1) vaccinated animals i.e. 0±0.00, 3.3±0.51, 3.4±0.51, 4±1.15 and 4.1±1.19 at zero, 7th, 14th, 28th, 48th day post-vaccination respectively. Similarly the mean antibody titers shown by the PPR (Nigeria 75/1) vaccinated animals were 0 ±0.00, 10.4± 3.86, 11.2±4.13, 20±11.31 and 21.6±11.80 at zero, 7th,14th, 28th and 48th day post vaccination respectively. Result of present study demonstrated
Summary
42
that the mean antibody titer values of animals vaccinated with Raksha PPR (Sungri 96) was significantly higher than animals vaccinated with PPR (Nigeria 75/1) at zero, 7th,14th, 28th and 48th day post vaccination respectively. The study also concluded that the mean antibody titer of animals receiving vaccination along with vitamin supplementation was significantly higher than animals receiving only vaccination. While performing the statistical analysis of data, it was revealed that the results were significant (p<0.05).
The present study summarized and concluded that the mean antibody titer values of Raksha PPR (Sungri 96) was significantly higher than PPR vaccine (Nigeria 75/1). As both India and Pakistan are two neighbouring countries, so PPR among them also falls in trans-boundary disease category. It signifies that both being part of Asia subcontinent and PPRV strain of lineage IV prevails in both regions. Keeping these factors under consideration proper vaccination strategy should be followed for the immunization of animals. In past, Nigeria 75/1 strain of PPRV vaccine had been used in Pakistan but the results were not reliable in terms of desired immune response and protection. Although titer was shown by this vaccine but protection is not reliable for proper health care of small ruminants. There was an immense need to come up with the authentic research on PPRV vaccine Raksha PPR (Sungri 96) in Pakistan which is already being used in India with desirable results.
The results of present research project were mostly similar with the findings of other scientists. The results of this study were analyzed through Independent t-test for independent samples. Availability: Items available for loan: UVAS Library [Call number: 2385-T] (1).

Publisher: 2015Dissertation note: Brucellosis is declared as one of the most widespread zoonoses in the world by the world's reknowned organizations. It is defined as a contagious systemic bacterial disease primarily of ruminants. The disease is manifested by late term abortions, weak calves, still births, infertility and also associated placentitis, epididymitis and orchitis, with excretion of the organisms in uterine discharges and milk. With the intensification of the import of animals and the establishment of big farms in the last few years, the incidence of brucellosis increased sharply in many countries, both in man and animals.
In this study 360 serum samples were examined from four groups of animals in district Mirpur Azad Kashmir. Blood samples of 3ml from buffaloes, cattle, sheep and goat (n=30) each were taken from three sub-divisions of Mirpur separately. The serum samples were screened by RBPT which is a screening test for brucellosis, and it was observed that 8.6% animals were seropositive by RBPT. The serum samples of cattle were 17.8%, buffalo were 8.9%, goat were 2.2%, and sheep were 5.6% positive respectively.
The serum samples positive by RBPT and some randomly taken samples were further confirmed by the use of most specific and sensitive serological test known as i-ELISA. 6.87% animals were confirmed as seropositive by i-ELISA including cattle (17.5%), buffalo (10%), sheep (0%) and goat (0%).
All RBPT positive samples were further subjected to RT-PCR. Among these 31 samples 24 were positive for Brucella genus and only 7 samples were negative. Samples were further tested for confirmation of Brucella species. All 24 samples were having Brucella abortus.
The data were analyzed by using the Statistical package for the social sciences (SPSS) program version 22. Data were analyzed using Chi-square test and Z-test statistics. Availability: Items available for loan: UVAS Library [Call number: 2378-T] (1).

Publisher: 2015Dissertation note: Bovine brucellosis is very important zoonotic disease in respect of outbreak that resulted in reproductive loses through storm of abortions in herds and infertility in bulls. Currently, no phyto treatment for complete recovery from brucellosis is available.
Phyto Chemo-immune therapeutic agents are effective for recovery from bovine brucellosis (Hypothesis)
Group A was comprise five adult cows (n=5) positive for brucellosis. Animals in this group were given 3 shots of Oxytetracycline LA at 20mg/kg BW (IM) repeated every 48 hrs. Streptomycin @ 13mg/kg BW IM was given for six consecutive days. Furthermore, flunixin meglumine @ 2mg/kg BW IM for 3 days in combination with antibiotic. Selevit injection containing selenium and vitamin E was administered (IM) for consecutive five days. At next day all the animals in this group were vaccinated with a combined vaccine of RB51 and FMD (Oil based) at a dose of 3mL/animal through deep IM route. In group B, all the animals were given Saafi (Herbal Product) orally consecutively for six days. Furthermore, flunixin meglumin @ 2 mg/kg BW IM was administered for three days. All these treatments were given simultaneously. Then injection Selevit containing selenium and vitamin E were administered (IM) for consecutive five days. After treatment all animals were vaccinated with RB51 + FMD (oil based) 3mL/ animals deep intramuscularly. In group C, flunixin meglumin @ 2 mg/kg BW IM was administered for three days. After NSAID, Selevit injection containing vit. E and selenium was administered (IM) for five days regularly. After treatment, animals were vaccinated with RB51 + FMD (oil based) 3 mL/ animals (IM). In D group five negative adult animals were included in this group and vaccinated subcutaneously with RB51 and FMD (Oil based) at a dose of 3 mL/animal.
Summary
40
Data regarding this study was analyzed with ANOVA and completely randomized design was used to compare the mean between different groups using statistical package for social science (SPSS) version 20. P < 0.05 was considered significant.
The results showed OD values after 1st, 3rd and 6th month were significantly different in all groups. The mean values depicted that OD values was significantly higher (2.886±0.099) in vaccinated (positive) animal’s vs the other three groups. There was no significant difference in OD values of herbal treated, antibiotic treated and health control animals. The lowest OD values was found in healthy control animals, though significantly similar with herbal treated, antibiotic treated. The mean OD value at 3rd month after treatment is significantly higher (1.794±0.090) in herbal treated and vaccinated positive groups but the OD value of healthy group was lowest (1.794±0.090) after 3rd month of treatment. After 6th month of treatment the OD value of positive vaccinated group was found significantly highest (1.146±0.194). On the other hand lowest value (0.595±0.079) was found in healthy control group.
All the groups have found non-significant difference in all group. Regarding Real time PCR the value range from 0-40 Ct values. In the present study the Ct values of the control positive was found to be 13 which indicate control positive. The antibiotic treated group had a Ct value found in this range 35.61 to 38.13. The herbal treated group were all positive and the values were 31.34 to 37.42 Ct. The vaccinated immune booster group. The Ct values in the group was found to be 30.83 to 34.21. The birth weight and placenta dropping time was normal in antibiotic treated animals. There were no significant results found in all groups.

Publisher: 2015Dissertation note: Brucellosis mainly infects food animals such as cattle, buffaloes. Brucella abortus is the principal cause of brucellosis in cattle and is shed from the infected animal at or around the time of calving or abortion. Brucellosis is zoonotic disease transmitted to humans both through Brucella abortus and melletensis.
The present study was conducted on 200 animals privately owned and publically owned abattoir. An epidemiological questionnaire focusing on trade animals as well as husbandry and sanitary practices that could be associated with the risk of Brucellosis infection was completed. Serum samples were collected and analyzed using Rose Bengal Plate Test. The serum samples positive for Brucellosis through RBPT further subjected to enzyme linked Immunosorbent assay. The samples of cattle collected from publically owned abattoir are subjected to the RBPT and the result was 18% and privately owned abattoir have an RBPT result of 10% and samples of the buffaloes are subjected to the test of RBPT as an screening test which was respectively 20% and 8%. The samples are further subjected to the iELISA and the results was shown that through ELISA the result was respectively 12% and 4%. While results for the cattle declared the prevelance of brucella infection through indirect ELISA was 8% and 2% at public and private abattoir respectively. The abattoir workers had a high risk to the exposure to the transmission of the disease as it is world widely more zoonotic the workers found positive for the brucellosis at public abattoir through RBPT shown no positive results. While in private abattoir through RBPT there is 6.66% animals were positive. However we concluded the results through indirect ELISA the results found were 66.66% and 15.62% for the butchers and meat sellers respectively at public abattoir.so the butchers are prone to the infection of the brucella antibodies.in comparison with the private abattoir 33.33% was detected in the abattoir cleaner. Through indirect ELISA.

Publisher: 2015Dissertation note: Fasciolosis is the disease of sheep, goats, cattle and other ruminants. Human and equines are unusual hosts in which instead of liver the flukes may found in lungs or under the skin. Transmission depends on an intermediate host lymnae snail. Animal ingest metacercaria, the worm migrates to the liver where it causes extensive damage and mature worm lives in bile duct. The disease occurs as an acute, sub-acute or chronic infection. Chronic Fasciolosis characterized by anemia, hypoalbuminaemia, emaciation, submandibular edema and loss of condition. Clinical disease is well known but sub clinical infections are often unnoticed, leading to marked economic losses, reduced milk yield, weight loss, reduced fertility and immunity, consequently leading to significant economic losses. Fasciolosis has recently been recognized as an emerging zoonotic disease. Infections in human may be asymptomatic but sometimes nonspecific pain in abdomen, anorexia, dyspepsia and vomiting may occur. Pain in right hypochondrium, epigastrium and jaundice occurs in chronic phase. Sometimes ectopic migration of worm causes abscesses in many organs.
The present study investigates the prevalence of Fasciolosis in sheep and goats at different geographic locations on the basis of altitudes in Azad Jammu and Kashmir. 4662 (sheep n=2242; goat n=2420) fresh fecal samples from sheep and goats were collected from three village/towns each of Mirpur, Poonch and Muzaffarabad Divisions. Stool samples were collected from 566 pastoral families of AJK to determine the zoonotic potential of the disease. Prevalence of the disease was calculated on the basis of centrifugal floatation and sedimentation techniques.
The intensity of infection was calculated using the McMaster egg counting technique. The risk factors of the disease studied included altitude, season, sex, age, and effect of deworming and flock size on the rate of prevalence. An overall prevalence was recorded as

17.88%. Prevalence of Fasciolosis in sheep revealed 26.49% and that of goats 9.91%. The data was analyzed using Chi-square test which revealed a significant difference (P<0.05) in the prevalence of the disease in sheep and goats. The overall prevalence rate in both species was recorded as15.09% at altitude <3000 feet, 25.00% at 3000-6000 and 15.74% at >6000. The highest prevalence was recorded at an altitude 3000-6000 feet. Chi- square values showed significant difference (P<0.05) among three different altitudes. The altitude of 3000-6000ft showed a significantly higher (P<0.05) prevalence of Fasciolosis in sheep and goats. The overall prevalence showed 13.93% rates in spring and 21.77% in autumn. Chi-square values showed a significant difference (P<0.05) in the prevalence of the disease, higher in autumn than Spring. Sex wise prevalence showed 16.67% in male and 18.59% in female animals. The data showed no significant difference (P>0.05) in Chi-square analysis. The prevalence of the disease in the age group below 1 year was 04.40%, 1-4 years revealed 17.73% disease and 36.18% in >4 year. The data showed significantly different (P<0.05) rates in all age groups. Highest prevalence was recorded in sheep and goats above 4 year of age and lowest in those below 1 year. The prevalence in animals with no recent history of deworming was recorded 23.22%. The data showed 15.37% disease in small flocks of sheep and goats <30 as compared to 18.72% in large flocks >30. Chi-square showed a significantly higher (P<0.05) prevalence of the disease in large flocks.
Generalized Linear Model (GLM) was used to evaluate the contribution of risk factors (epidemiological factors) to the variations in the prevalence of Fasciolosis in sheep and goats. All the epidemiological factors i.e. altitude, species, season, gender, age group, deworming and flock size were processed. The deworming appeared to be the most significant factor in the model contributing maximum variations in disease with highest Odds followed by age groups,

species, season, altitude, flock size and gender. The risk factors for the Fasciolosis in sheep and goats were found, lack of practice of deworming, age group >4 year, species sheep, season Autumn, altitude 3000-6000 and flock size >30. The 75% of the disease prevalence was due to above mentioned risk factors. The deworming, specie goat, age group <1 year, season Spring, altitude <3000, and flock size less than 30 were appeared to be the protective factors in the Generalized Linear Model.
The intensity of infection was analyzed through Factorial analysis for difference in species, altitude and season. The difference in eggs per gram of feces was found significantly different (P<0.05) in sheep and goats. The effect of season on egg per gram (EPG) of feces showed a higher mean values in sheep (191.49) and goats (219.72) in Autumn as compared to 158.04 and 180.61 in Spring. In both seasons the mean for goats was found higher than sheep. The effect was found significant (P<0.05), higher during Autumn. Factorial analysis of the data showed significant interaction (P<0.05) between species and altitude. The data showed mean values for sheep 174.04, 191.87 and 168.33 at altitude <3000, 3000-6000 and >6000 feet respectively. The mean values for goats were 232.22, 194.95 and 170.59. The data revealed higher mean for goats as compared to sheep on all three altitudes. Goats revealed significantly higher (P<0.05) number of EPG. POST HOC Tukeys test showed a non-significant difference in intensity of disease between <3000 and 3000-6000 feet, rest of the differences were significant (P<0.05).
The overall prevalence in pastoral communities of AJK was 0.88%. The samples were collected from male and female of 4 age groups <10 year, 11-20, 21-40 and >40. The prevalence in male was 0.76 and in female was 0.98%. The data showed that age groups below 20 year were

the susceptible groups in both sexes. The highest prevalence (2.25%) was found in female age group 11-20 year. Age groups above 20 year did not revealed any positive sample.
227 adult liver flukes were collected from livers of infected animals of different animal species (sheep, goats. cattle and buffaloes) and geographic locations for morphometric and molecular identification of the species of Fasciola. Flukes were identified on the basis of measurements of body length, body width, diameter of suckers, distance between oral and ventral sucker and distance between ventral sucker and posterior end of the body. The measurements of F. hepatica showed a body length range 13-34mm with an average length of 21.51mm whereas, F. gigantica ranged from 28-52mm with an average of 42.27mm. The average body lengths of F. hepatica below 3000ft was 21.9, at 3000-6000ft was 21.07 and above 6000 ft was 22.00mm and that of F. gigantica was 42.05 and 42.44mm at 3000 and 3000-6000 feet. The measurements of F. hepatica revealed an average body width of 10.05mm, average diameter of oral and ventral suckers of 0.74 and 1.28mm respectively and average distance between the two suckers of 1.34mm. The readings for F. gigantica were 9.46, 0.89, 1.55 and 1.72mm respectively. Average distance between ventral sucker and posterior end of the fluke in case of F. hepatica was 18.35mm at all three altitudes and host species of animals and it was 38.26mm in case of F. gigantica. The overall mean worm load was 13.56 worms per liver of animal with a range 5-26. The mean worm load of F. hepatica was 10.9 and that of F. gigantica 13.11. Mixed infections were noted at altitudes below 6000 ft. Infestation with F. gigantica was not found at altitudes above 6000ft and F. hepatica was encountered at all three altitudes. 51.98% of the recovered flukes were F. gigantica which showed the equal chances of infection with either species of Fasciola in AJK. The results revealed that F. hepatica was the fluke affecting animal population at altitude above 6000 ft and F. gigantica was the major fluke below

3000 ft. At altitudes between 3000-6000ft, 36.20% of flukes were F. hepatica while its prevalence was reduced to 17.30% below 3000 ft. Once the species of the liver flukes were identified morphologically they were subjected to molecular conformation through amplification of the genomic DNA of the two species through PCR using two sets of species specific primers. In the PCR based on primer set 1, a product of 391 bp was generated from the genomic DNA of Fasciola hepatica whereas no product was generated from the DNA of Fasciola gigantica. PCR based on primer set 2 amplified a 235-bp product from the DNA of Fasciola gigantica. The molecular identification in the present study showed that morphometric identification of the two species is valid and standard population of both species were found present at different geographic locations and species of the animals of the state of Azad Jammu and Kashmir except F. gigantica not found above 6000 feet altitude.
The ethno veterinary practices for Fasciolosis were documented through Participatory Rural Appraisal. A total of 173 respondents/key informants were interviewed during the study period in the study area. The majority of the traditional healers (n=33) elders of pastoral families (n=53) and sheep/goats owners (n=56) were above the age of 40 year.

Publisher: 2016Dissertation note: Foot and Mouth Disease is a highly contagious viral disease of all cloven footed animals.
The best control strategy of this disease is effective and in time vaccination. A successful
vaccination campaign depends on the serotype identification and specific vaccination against the
prevalent serotype of the virus. The present study was designed to evaluate comparative potency
of two anti-FMDV vaccines (UVAS-FMD, Deccivac Intervet) used in cattle around areas of
Lahore Pakistan. Blood samples were taken from vaccinated animals on day 0, 30, 60 and 90
post priming. Antibody titer was evaluated with different route of administration and various
adjuvant based vaccines. Four animal groups were made each containing 5 animals; in group 1
UVAS vaccine was used by Sub/ Cut route (gel based) at priming dose, followed by Intra
Muscular (oil) on 30th day. In group 2 UVAS vaccine was given I/M (oil) as priming dose and
booster (oil) I/M. In group 3 Deccivac (oil) vaccine was used I/M for priming and boosting. In
group 4 Deccivac (oil) vaccine was used as Sub/ Cut for priming and boosting. The results
revealed non-significant difference (p>0.05) among the four different groups administered with
FMDV vaccines when evaluated at day 30 and significant difference (p<0.05) at day 60 and 90
post vaccination. Analysis of variance showed significant difference (p<0.05) in antibodies
between groups and with in groups at day 60 and 90. Gel based vaccine gave quick antibody
response which later maintained with oil based booster dose. The difference in antibody titers
obtained in the present study was found non-significant (P>0.05) between the antibody titers of
FMD trivalent vaccine of UVAS and Deccivac at 90th day of inoculation. There was significant
difference (p<0.05) between the adjuvants of vaccine. Animals inoculated with priming dose of
gel based vaccine followed by oil based boosting showed significantly high anti FMD antibody
titer than animals inoculated with oil for both priming and boosting. There was significant

difference (p<0.05) between the groups vaccinated with various routes of administration. The
animals inoculated with priming dose through s/c followed by boosting dose i/m showed
significantly high anti FMD antibody titer at 90th day of inoculation compared with those
inoculated intramuscularly for both priming and boosting. The animals inoculated with oil based
vaccine for both priming and boosting through S/c showed marked significant decreased in anti
FMD antibody titer. The route of administration revealed significant difference (p<0.05) in
antibody response within groups and between groups at day 30, 60 and 90. In all three readings
the mean for sub/cut priming and IM boosting were found significantly high (p<0.05) as
compared to other routes. In conclusion it is recommend from the study that FMD vaccination
with sub/cut priming and booster dose with IM route. Availability: Items available for loan: UVAS Library [Call number: 2499-T] (1).

Publisher: 2016Dissertation note: Johne’s disease (JD) or Paratuberculosis caused by Mycobacterium avium subsp.
Paratuberculosis (MAP) is characterized by an incubation period of several years. It is a chronic
non-treatable disease of animals causing enteritis which ultimately leads to economic losses to
dairy and meat industries worldwide. To estimate sero-epidemiology of the JD through ELISA is
inexpensive, efficient, single step and sensitive for the detection of antibodies in cattle and
buffaloes. So, keeping in view the economic and public health significance of the disease, the
present study was designed with the objective to estimate the sero prevalence of JD using
indirect ELISA and to quantify the effect of JD on the level of serum proteins in cattle of D. I.
Khan district, Khyber Pakhtunkhwa Province. Johne’s disease is prevalent in cattle of D I Khan
that affects serum proteins level in dairy animals.
For the study animals were well restrained and about 5 ml blood was collected in Non-
EDTA coated vacutainer from the jugular vein of each animal using 5 ml disposable syringe,
after collection and proper labeling samples were transferred in Ice packed cooler to
Microbiology laboratory, Govt. College of Veterinary Sciences D.I Khan. Serum was collected
at the top of the vacutainer with the help of disposable pipette and was stored in eppendorf tubes
in deep freezer until transported to University of Veterinary and Animal Sciences, Lahore for
further analysis. Data was captured on questionnaires about the clinical signs and symptoms,
management practices and possible risk factors associated with Johne’s disease, was obtained
from the owners.
Summary
40
The collected serum samples were analyzed by Indirect ELISA using commercial ELISA
kit (Mycobacterium Paratuberculosis Antibody Test Kit, IDEXX, USA) according to
manufacturer instructions.
The ELISA positive samples were processed further for the estimation of serum protein analysis
using Biuret method (Doumas et al. 1981;Spencer and Price. 1977).The serum albumin was
determined by Photometric colorimetric test (Bromocresole green (BCG) method (Spencer and
Price. 1977).The globulin will be estimated by subtracting serum albumin from serum total
proteins (Javed et al. 2010).
Data regarding sero-prevalence by indirect ELISA were analyzed through Pearson's Chisquare
Test, while data regarding the effect on serum protein was analyzed by simple t-test using
statistical package for social sciences (SPSS) version 20. P < .05 was considered significant.
The present study demonstrated (12.7%) prevalence of MAP in cattle population of D.I
Khan. There were no significant effect of MAP on serum biochemical profile. The results of all
variables studied as under breed, gender, age, vaccinated status and management system. The
most frequent level was observed in females 13.7% as compared to males 0% (0/4). Among
different age groups, higher sero-prevalence 33.3% were present at age group above 6 years
while sero-prevalence of 7.1% in 2-3 years and 0% were recorded in age group 4-6 years.
Statistically a significant different were present between these groups. Moreover, there was no
relationship of vaccination status with disease because the prevalence recorded 16.6% and
vaccinated cases positive were recorded 0% but there was no significance difference among two
groups of animals. Breed wise risk factor statistically significant because the MAP cases were
highly prevalent in non-descript cattle 25% as compared to crossbred 5.8% and Sahiwal 0%
cattle breed. BCS category I had highest prevalence 66.6% while in BCS category II prevalence

was 23.8% and in BCS category III the prevalence was 0% recorded. Statistically the BCS of the
disease animals was significantly associated. Highest prevalence 100% were recorded above 60
days of diarrhea duration while 0% were recorded less than 60 days of diarrhea duration.
Statistically the sero-prevalence of diarrhea duration was highly significant. Management wise
sero-prevalence of Johne’s disease on the type of housing was higher in open 19.2% as compared
to confined 6.8% showing non-significant difference statistically. Sanitation wise seroprevalence
were higher in poor 19.2% as compared to good sanitation 6.8% showing also nonsignificant
difference statistically. Sero-prevalence of disease was less in well water 0% as
compared to tap water 25% showing there were a significant difference between the seroprevalence
of Johne’s disease under different water conditions. The results of total protein
analysis was statistically non-significant. Availability: Items available for loan: UVAS Library [Call number: 2526-T] (1).

by Muhammad Haseeb Saeed (2008-VA-241) | Prof. Dr. Aneela Zameer Durrani | Dr. Hassan Saleem | Prof. Dr. Azhar Maqbool.
Material type: ; Literary form:

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