Publisher: 2012Dissertation note: Dengue fever is the most common mosquito-borne viral infection of humans worldwide and is a major public health concern, especially in tropical and subtropical regions (Mackenzie et al., 2004). This life threatening disease is caused by a specific virus (ARBO-Flavivirus) transmitted by the bite of a female mosquito (Aedes aegyptii and Aedes albopictus) which is identified by the white bands and scale patterns on its legs and thorax. Trans-ovarial transmission of dengue virus has also been reported in different studies. The mosquito may bite at any time but the probability of bites increase at dusk and dawn (WHO 2009).
Dengue fever has emerged as a significant public health problem in Pakistan. In Pakistan, the first epidemic of dengue fever was reported in 1994 in Karachi (Anaari et al., 2001). Several years later, in 2006 another epidemic was reported in the southern part of Pakistan, predominantly caused by DENV-2 that led to 58 deaths (khan et al., 2008). In 2007, 22 people died of disease and in 2008 only five people were reported to die from it. Between October 2006 and January 2008, there were 3,242 laboratory confirmed cases of dengue fever in Pakistan. Since January 2009, 224 suspected cases were reported in Sindh province, of which 135 were the confirmed cases. During the epidemic of dengue fever in 2010 more than seven thousand cases were reported in Pakistan, of which 5 thousand cases were from Punjab and resulted in 63 deaths.
The mosquito-borne viral hemorrhagic diseases are prevalent throughout the world. Dengue hemorrhagic fever (DHF) is one of the most important diseases widely distributed in the tropics of South East Asia. It is an infectious malady of human beings characterized by fever and non-specific constitutional symptoms. The virus is transmissible to human beings by the bite of female Aedes aegypti and Aedes albopictus. The disease is spreading like a geometric rise of cases in a wide range of geographical regions.
The geographical factors and locality of patients may be a contributing factor to the outbreak of Dengue Fever. Climate change is likely to increase the area of land with a climate suitable for dengue fever transmission, and that if no other contributing factors were to change, a large proportion of the human population would then be put at risk.
The data on address of patients were collected from all the patients admitted in tertiary care hospital from August 01, 2011 to November 30, 2011. The geographical risk factors studied in this project were presence or absence of parks, trees, ponds, swimming pool, service station, tyre shop, source of stagnant water, pond and municipality garbage tank in vicinity of house of the cases and controls. For the study of risk factors we made 2 groups i.e. cases and controls; each comprising of 300 subjects and then data on presence or absence of various hypothesized risk factors in the vicinity of house (400 meters) and area (800 meters) were collected through a well structured and pre-tested questionnaire (Harrington et al., 2005; Honório et al., 2003; Schatzmayr 2000; Muir and Kay 1998; Reiter et al., 1995; McDonald 1977; Hausemann 1971 and Bond et al., 1970).
The statistical analysis of data was done by using SPSS 16.0. Qualitative data were presented in form of tables, bar charts, column and pie- charts. Chi-square test was applied to see the association between dengue fever and various hypothesized risk factors. P-value<0.05 was considered as significant. Odds ratio was calculated at 95% level of confidence (CI) for various hypothesized risk factors of dengue fever.
The results of present study revealed that the season of dengue fever in Pakistan is from August to November and the period prevalence of dengue fever to be 0.11%. Males (59%) were mainly the victim of dengue fever. The main affected age groups were 16-30 year (37.33%) and 31-45 years (29.67%). As far as the geographical distribution of dengue fever infected patients is concerned, it was concluded that dengue fever cases were reported from all the ten towns of Lahore metropolitan, however, most of the cases were reported from Ravi town followed by Data Ganj Baksh town and Cantt.
The results regarding various hypothesized risk factors are as follows: parks/trees/plants in vicinity of house OR=8.81, p-value <0.05; swimming pool in vicinity of house OR=5.O3, p-value <0.05; source of stagnant water in vicinity of house OR=8.25, p-value <0.05; fogging in your area OR=0.50, p-value <0.05; service station in the area OR=5.98, p-value <0.05; tyre shop in the area OR=6.11, p-value <0.05; municipality garbage tank in the area OR=5.88, p-value <0.05; any pond in the area OR=5.69, p-value <0.05.
From the results of this project we concluded that dengue fever is most prevalent from August to November and it is a disease of mainly male gender and mostly affects people of age group 16-45 years. Besides this, dengue fever is almost equally distributed in all the towns of Lahore metropolitan. Also we concluded that presence or absence of parks, trees, plants, swimming pool, stagnant water, pond, service station, tyre shop and municipality garbage tanks in vicinity of house are the risk factors of dengue fever. Fogging proved to be a deterrent to dengue fever.
On the basis of results of this project there is need to implement a control program in which vector control and minimizing the exposure of people to risk factors should be the key points that need to be addressed.

Publisher: 2012Dissertation note: The present study was conducted to check the prevalence of antibiotic resistant Staphylococcus aureus in milk, milk products and food handlers at various dairy retail shops in Lahore. A total of 100 samples, 30 samples of raw milk, 30 samples of pasteurized milk, 20 samples of yogurt, 10 samples of butter and 10 hand swabs samples of dairy handlers were analyzed. Staphylococcus aureus was detected in 54% (54 out of 100) samples.
Overall high prevalence was recorded in raw milk, followed by hand swabbing samples of dairy handler, butter, pasteurized milk and yogurt. The results indicated unhygienic practices during milking and handling of milk at different critical control points such as transportation, storage, and post-pasteurization contamination. Overall high prevalence of ampicillin and amoxicillin resistant Staphylococcus aureus were recorded in all the samples of milk and milk products and the hand swabbing of dairy handlers, followed by resistant against chloramphenicol, trimethoprim, streptomycin and vancomycin respectively. All the isolates were resistant to ampicillin followed by resistance against amoxicillin, chloramphenicol, trimethoprim, streptomycin and vancomycin which were 92.6%, 37%, 33.3%, 24.1% and 22.2% respectively.
The antibiotic resistant Staphylococcus aureus in milk and milk products indicated the widespread use of these antibiotics in treating different types of infections associated in either livestock or humans which results in selection pressure of these antimicrobials and results in the emergence of these antibiotic resistant bacteria in different environmental conditions. The risk associated with human health as a result of ingestion of these antibiotic resistant bacteria can be prevented by adopting hygienic measures during milking, transport, storage and hygienic handling by the handlers so the human health can be assured.

Publisher: 2012Dissertation note: Haemoprotozoan infections in ruminants are of significant importance in tropical and subtropical regions of the world. Diseases are transmitted through ticks thus a number of epidemiological factors/risk factors are involved. Ovine Babesiosis is one such disease posing problems in Pakistan which is an agricultural country and livestock plays an important source of income for farmers. The economic losses in small ruminant production are significant in the tropical and subtropical regions of the world. Carrier sheep infected with Babesiosis are challenge to current diagnostic methods and are difficult to detect because of the low number of parasites in circulation. However diagnosis of carrier animals in herd is important for preventing outbreaks by transmission through vector ticks to healthy animals and for obtaining epidemiological data of disease. The work done on Babesia ovis is negligible. For this purpose a study was conducted at two farms to measure the prevalence and optimization of PCR for Babesia ovis. Blood was collected into an anticoagulant containing vacutainer. First thin smears were formed and stained with Giemsa stain for microscopic examination of Babesia ovis. For DNA extraction Puregene DNA purification system, Gentra, was used. Extracted DNA was amplified in a thermolyser using B. ovis primers and then analyzed using electrophoresis on 1% agarose gel. Microscopic examination demonstrated a prevalence of 16 % while PCR results revealed prevalence of 29% for B. ovis. Results displayed that the efficacy of PCR is more sensitive than Light Microscopy. Data on infection rate between male and female and between different age groups was statistically non-significant. Herd wise prevalence was 36% and 22% in Livestock Production Research Institute, Bahadarnagar, Okara and Small Ruminant Training and Research Center,Ravi Campus, Pattoki respectively. Common sites of attachment for the ticks were under the tail, perineal region and underneath ears.The data was analyzed by using SPSS (Statistical Package for Social Sciences).

Publisher: 2012Dissertation note: A cross sectional study was conducted during February 2012 to April 2012, in Chagai district, Balochistan. Information about education and economic status of the farmers, managemental practices, vaccination, outbreak history, veterinary services and transboundry animal movement was collected from 323 (282/323 farmers and 41/323 livestock traders) on a structured questionnaire. The status of foot and mouth disease (FMD) is not known in Chagai, following research has been planned to see the potential association between farming practices and FMD.
Factors which were significantly associated with the occurrence of foot and mouth disease in district Chagai were education level of Farmers (illiterate 60%, literate 40%) and livestock traders (illiterate 42%, literate 58%), socioeconomic status of the farmers <20000 rupees (63%) and >20000 rupees (37%) and livestock traders <20000 rupees (12%) and >20000 rupees (88%), type of animals in the herd of farmers (cattle, 2%, sheep 4.2%, goat 19%, cattle-sheep-goat 9% and sheep-goat 67%) and livestock traders (cattle 17%, goat 3%, cattle-sheep-goat 68% and sheep-goat 12%), housing system used by farmers (open 93%, closed 7) and livestock traders (open 12%, closed 78%), feeding methods in case of farmers (grazing 93%, stall feeding 7%) vaccination against FMD farmers (yes 3%, no 97%) and livestock traders (yes 39%, no 61%), veterinary services available to farmers (yes 17%, no 87%) and livestock traders (yes 48%, no 52%) , nomadic movement of farmers (yes 62%, no 38%), export of live animals (yes 73%, no 27%) and import (yes 10%, no 90%). Other managmental practices like quarantine (no, 100%), isolation of sick animals from the herd (no, 100%), feeding of young animals milk of the sick mothers (yes, 100%) and proper disposal of the dead animals (no, 100%) were factors which were not analyzed due to zero cell values.
It is concluded that illiteracy, poor economic status of farmers, type of animals (sheep and goat), open housing system, mixed grazing in the range land, low vaccine coverage, poor veterinary services and free movement of animals are strongly associated with the occurrence of foot and mouth disease in Chagai district. Transboudry animal movement of livestock to and from Afghanistan and Iran can aggravate the situation. Regular vaccination of livestock and awareness of farmers can help to improve the animal health status in Chagai.

Publisher: 2013Dissertation note: Tuberculosis is chronic infectious disease of animals and human beings, which is characterized by progressive emaciation, nodules formation in lungs and involvement of local lymph nodes. Tuberculosis is caused by mycobacterium species and it is endemic in Pakistan. In the world ranking regarding tuberculosis patients, Pakistan is on 6th position.
A case control study was conducted in Peshawar city and its suburbs in order to determine the risk factors of tuberculosis in dairy animals. Prevalence of tuberculosis in dairy animals recorded in this study was 18.27%. A total of 750 dairy animals were included in the study in which 250 were positive cases and 500 were controls on the basis of tuberculin skin test. Controls were divided into two groups, group 1(animals above 1 year of age) group 2(animals under 1 year of age). All these animals were selected from civil veterinary hospital Peshawar and veterinary teaching hospital (University of Agriculture Peshawar); and villages located on ring road of Peshawar city.
Data was collected from the owner on pre designed questionnaire to determine different risk factors associated with tuberculosis and it was analyzed by using SPSS 16.0. The calculated odds ratio in descending order were 2.70 for rotational grazing practice, 2.52 for keeping donkey with dairy animals, 2.22 for not having own bull for breeding, 2.05 for keeping animals inside the shed at night, 2.02 for living in rural geographical environment, 1.87 for low socio-economic status, 1.65 for not using tap water, 1.59 for herd size more than 16-30 animals, 1.47 for non lactating animals, 1.47 for illiterate owners, 1.42 for contact with wild animals, 1.30 for keeping old animals within the herd, 1.25 for using fertilizer on crops that offer to animals, 1.22 for cattle, 1.17 for dung disposal weekly and 0.45 for deworming practice in dairy animals. Odds ratio more than 1 was considered being a risk factor while less than 1 was being considered as a health promoting factor. P-value < 0.05 was considered as significant.
Tuberculosis is disease of zoonotic importance, and its incidence increasing day by day both in humans and animals. Therefore further research is the need of time to control and eradicate this disease globally.

Publisher: 2013Dissertation note: Toxoplasmosis is a protozoan disease of cats, however all warm blooded animals comprising mammals, birds and human beings can be infected with it. The disease is manifested by abortion, resorption, neonatal loses, birth of weak kids, birth defects and mummification of fetuses in pregnant animals. Global seroprevalence of Toxoplasmosis is continuously evolving in animals and human beings. Keeping in view the zoonotic importance of Toxoplasmosis, the present study was conducted, in Fort Minro, to determine the seroprevalence and potential risk factors of Toxoplasmosis in goats and their attendants.
A total of 52 pastoral goat herds with herd size of "?20 - ?40" animals per herd were selected by convenient sampling technique. Out of these 52 pastoral herds, 237 goats were selected by systematic sampling method i.e each 5th unit was selected for sampling. The goats were sampled if the age of goats was ?6 months. Most common breeds of these herds were, Pahari and Hairy goat breed. A total of 92 herd attendants were also selected to determine the zoonotic potential of Toxoplasmosis in Farm workers / attendants.
All serum samples were screened by LAT. For this purpose, the commercial Latex agglutination kit (Wiener Laboratorios S.A.I.C. Riobamba 2944, 2000 Rosario Argentina) was used for detection of specific antibodies of T.gondii in serum of goats and their attendants. A herd was considered as a positive, if at least one goat was found to be positive in that specific herd. Out of total 52 goat herds, 36 herds presented at least one or more than one seropositive animal. The number of positive animals in each herd, ranged from 1-10 animals. Out of 237 goats, 64 goats were positive for Toxoplasma gondii antibodies. Thus overall seroprevalence of Toxoplasmosis in goats was 27%. The seroprevalence was significantly high in female goats (21.5%) as compared to males (5.5%). Kajli/Pahari goat breed was more positive (14.8%) as compared to Hairy goats (12.2%). An increase trend of seropositivity was observed in goats with increase in age. Age group of "?3 years" of goats had highest share of percentage prevalence to overall prevalence of Toxoplasmosis, followed by age group "?1-<3 years", while age group "?6 m-<1Year" had lowest share of percentage prevalence to overall prevalence. Prevalence in males had 5.5% share in overall prevalence (27%) while prevalence in females had 21.5% share in overall prevalence. Data analysis of various risk factors determined that natural reservoirs of water, pastoral grazing and presence of cats and dogs were major risk factor of Toxoplasmosis in goat herds. Access of cats to drinking water and food resources and eating medium cooked meat were major risk factors for goat attendants.
High prevalence of Toxoplasmosis in goats and Farm workers, suggests that Toxoplasmosis is endemic in the study area and further epidemiological studies should be focused on goat meat, milk and milk products. It is concluded that Toxoplasmosis can be reduce in human beings and animals by reducing risk factors and maintaining proper hygienic measures.

Publisher: 2013Dissertation note: 6.1 Background
Antimicrobial resistance is an under-appreciated threat to public health in nations around the globe. With globalization booming, it is important to understand international patterns of resistance. Thermotolerant Campylobacter spp. are considered to be the most frequent cause of human acute bacterial enteritis worldwide, furthermore, numerous transmission vehicles are known, but raw milk, untreated surface water and especially poultry meat are major sources of human infections. In Pakistan studies reveal that among meat samples, the highest prevalence (48%) of Campylobacter was recorded in raw chicken. Therefore, the increasing level of resistance to the antibiotics among Campylobacter spp. is recognized as emerging public health problem.
6.2 Hypothesis
" Campylobacter spp. was present in the poultry meat at retailer shops.
" Unhygienic measures concerning to meat handling had a considerable effect on the prevalence of antimicrobial resistant Campylobacter.
6.3 Methodology
A cross sectional study of 3 months duration was carried out in the Lahore city of Punjab, Pakistan. Using the standard microbiological techniques and statistical analysis, the prevalence of Campylobacter and its pattern of antibiotic resistance were evaluated. Furthermore, through premeditated questionnaires, public awareness regarding meat-borne diseases, food safety and inappropriate usage of antibiotics were assessed as well.
6.4 Statistical design
Data will be analyzed by using SPSS version 20.0. Quantitative variable were presented by using mean ± S.D. Qualitative variable were presented with help of frequency tables, pie charts and bar charts. Chi-square test was applied to see the association among different variables. P value <0.05 was be taken as significant.
6.5 Outcome
Through this cross-sectional study, the prevalence and pattern of the antibiotic resistant campylobacter was assessed; moreover public awareness with special reference to food safety, knowledge of meat borne diseases and usage of antibiotics wereevaluated. Furthermore, one could play an influential role in public health by dissemination of awareness among the masses about the proper usage of antibiotics and food safety measures.

Publisher: 2013Dissertation note: Pakistan is home to pastoralist since centuries. Present study was based on epidemiological survey of major health related problems in nomadic herds of camel in district Bhawalnagar. This district is one of camel rich districts of Punjab. Cross sectional survey on major health problems was conducted through a close ended questionnaire.
Twelve major health problems were selected that are common in herds of camel. Camels were categorized in three age groups: <4 years, 4-10 years and >10 years. Ranking of health problems gave following results: calf diarrhea 19.6%, tick infestation 17.2%, mange and gastrointestinal parasites 12.5%, trypanosomiasis 10% and pneumonia 8.8%. Further investigation presented following picture: calf diarrhea, mange and pneumonia were problems of <4 year age group. Trypanosomiasis and gastrointestinal parasites were problems of >10 year age group. Tick infestation was the problem of 4-10 year age group. Nasal bots and sudden deaths were problems of > 10 year age group. This ranking was based on age, sex, mortality and case fatality. P-values were also found out by correlating different parameters. These values were collected separately for the camels of Rangers. There was significant difference in the values of camels of Rangers and nomads. Rangers camels had less health problems due to better managemental practices.
One part of questionnaire was based on managemental practices in nomadic herds of camel. Investigation of managemental practices gave following results: 60% herds had herd size of 11-20 camels, 37.6% herds of camel were kept along livestock, 58.3% herds had Marrecha breed, 56.7% herds had nomadic production system, 92.9% herds had feeding pattern of grazing, 58.3% adopted seasonal migratory pattern, 91.3% herds did not adopt vaccination and quarantine practices, 91.3% adopted ethno-veterinary practices and 58.3% herds had no access to modern veterinary facilities. Correlations were found out between different parameters and p-values came to be significant.
Third part of study was on detection of gastrointestinal parasites. Direct sedimentation and centrifugal floatation techniques were used for this purpose. 166 fecal samples were tested for gastrointestinal parasites and 90 (54.2%) samples came to be positive. Five types of gastrointestinal parasites were detected with following ratio: Emeria sp. 18.1%, Fasciola sp. 8.4%, Trichuris sp. 8.4%, Capillaria sp. 4.2% and Marshallagia sp. 15.1%. Female adult group had the highest percentage of parasites 46.3% followed by male young group 33%. Chi-square was used to find out association between different variables and P-values were calculated.
Nomadic herders of study area are earning their living by rearing and selling camels. This area has great potential for camel farming due to its unique physiogeography. There is dire need to encourage the local nomads by facilitating them by provision of veterinary health cover, better marketing facilities, and training of manpower for breeding techniques. Government interventions for the welfare of this animal can be much fruitful in terms of camel research and systematic production. This action will not only help in improving the shortage of meat, milk but also will elevate the socio-economic conditions of local nomads.

Publisher: 2013Dissertation note: In spite of the significance of dairy animals to poor citizens relatively is the neglected area of research. Considering this an active surveillance based study was conducted to analyze the impact of climate change on the epidemiology of diseases in dairy animals in Khyber Pakhtunkhwa (KPK) province, Pakistan. Ecologically and geographically two different clusters having four randomly selected districts each; furthermore randomly a single village from each district was selected. Data from 1252 (49.8%) cattle and 1260 (50.2%) buffaloes was collected on a predesigned questionnaire about the epidemiological parameters for the period of one year i.e. from July 2012 to June 2013. The results revealed a significant (p < 0.05) association of change in environmental temperature with the morbidity, mortality and case fatality rate of the diseases and major health problems. As the mean temperature at lower altitudes (below 500m) increases above 300C the rates of incidence of disease also increases. While at higher altitudes temperatures when increases above 300C the rate of incidence increases faster than in HCC. In CCC, the higher morbidity rate was due to ID in cattle and RB in Buffalo population and in HCC RB was higher morbidity causing health problem in both species. While in terms of mortality and case fatality HS was the leading cause in both clusters and species. The results also showed that the susceptibility of buffaloes and cattle to heat stress varied significantly according to specie, breeds, genetic potential and life stage. It was concluded that climate change do have an impact on occurrence, pattern and severity of health problems and infectious diseases at different altitudes. Further research work is needed to find out the best breeds in terms of production and reproduction that could well establish themselves in these climates.

Publisher: 2013Dissertation note: Pakistan has been bestowed with a huge population of livestock encompassing buffalo, cattle, sheep, goat, camel and other domestic animals such as cats, dogs, rabbits, etc. Out of these, dogs occupy a special attention due to many peculiarities they possess like sniffing, hunting, retrieving and many more. These specialties of dogs are utilized by military, rangers, police, anti-narcotic forces, other agencies, etc. There are three million dogs in Pakistan. A dog encounters many infectious and non-infectious diseases during the course of its life cycle. Some of the viral infectious diseases, and considered more important for a dog are, rabies, canine parvovirus infection, canine distemper, and infectious canine hepatitis. As a pathogen, canine parvovirus emerged in 1970s but later it evolved into two new antigenic strains, type 2a and type 2b which are distributed all over the world. Mostly, protection against CPV is gained from maternally derived antibodies in puppies but simultaneously they may interfere with CPV vaccination. Severe gastrointestinal signs are associated with CPV and this infection is transmitted through contact with infected feces via oro-fecal route or exposure with fomites and also via placental transmission. The virus is very stable in the environment and is susceptible to some cleaning agents like bleach.
The current study was conducted to study the descriptive epidemiology of canine parvovirus disease in dogs at Pet Center, University of Veterinary and Animal Sciences (UVAS) in Lahore and to compare two types of hyper immune sera i.e. Canglob (Ghazi Brothers) and UVAS hyper immune serum for parvovirus through interventional trial, for treating the clinically diseased pups. The study included puppies aged between six weeks and six months. Puppies aged between six weeks and six months, found clinically suspected to be affected with canine parvovirus and showing the signs and symptoms like vomiting, bloody mucoid diarrhea, emaciation and anorexia and found positive for hemagglutination test were included in the study. Hemagglutination test was used as a diagnostic and a screening test to confirm canine parvovirus in the clinically suspected puppies.
The disease was more observed in the puppies aged between 7 to 12 weeks. There were 28 females and 32 males observed in the study. The disease was more frequently observed in Labradors. The disease was observed to be more common in the dogs that weighed 4-6 kgs. Canine parvovirus HA titers were more observed in the dogs that had been ill due to CPV for the past 5-6 days. Only 16 puppies out of 60 were vaccinated. Also, it was observed that canine parvovirus geometric mean titer was higher in the non-vaccinated puppies. The disease was more observed in the pups vaccinated with a polyvalent vaccine and less observed in the pups that were inoculated with a monovalent vaccine. Most of the dogs were aged between 31-60 days when they got vaccinated. Sixty percent (60%) of the dog owners knew that if vaccination is done then the dog may be protected against the disease. The disease was more observed in the pups that were owned by more educated and economically stabled persons.
The result of the statistical analysis using Pearson Chi-Square Test suggests that the difference between Group A and Group B regarding the outcome of the interventional trial is not statistically significant. Therefore, the hypothesis is accepted that the UVAS produced hyper immune serum against canine parvovirus is equally good as compared with Canglob for the treatment of CPV diseased puppies.

Publisher: 2015Dissertation note: Pakistan has been renowned as an agricultural country. It is rich in livestock sector having fairly large populations of domestic animals. Among these, populations of cattle and buffalo are 38.3 and 33.7 million respectively. The importance of cattle and buffalo cannot be denied at any level as these are the principal farming animals and milk and beef are widely consumed locally in the country. The estimated annual milk production of cattle and buffalo include 17.372 and 30.462 million tonnes respectively and a combined 1.829 million tonnes beef for human consumption during 2012-2013 (Pakistan Economic Survey 2012-2013).
Brucellosis, a worldwide bacterial zoonosis, is one of the most serious diseases causing huge loss to national economy and human beings among developing countries (Wu et al. 2013). The disease is endemic in Middle East, Central Asia, Africa, Mediterranean region and parts of Latin America (Gwida et al. 2010). Brucellae are Gram-negative bacteria, facultative anaerobic and intracellular pathogens. These show a wide range of host specificity. These coccobacilli measure from 0.6 to 1.5 µm long and 0.5 to 0.7 µm wide. Eight species have been identified in the genus Brucella such asBrucella abortus(B. abortus affecting cattle and buffalo), B. melitensis (sheep and goats), B. ovis (sheep), B. suis (swine), B. canis (dog), B. neotomae (desert rats), B. ceti (cetaceans) and B. pinnipedialis (pinnipeds) (Blasco 2010). This wide range of species covers almost all domestic animals however cats have found resistant. Generally it is considered as a reproductive problem in both male and female animals (Ficht 2003).
Brucellosis has been listed as the second most serious zoonotic disease in the world after rabies by OIE (OIE 2009). B. abortus, the primary cause of Brucellosis in large ruminants, (cattle and buffalo), remains not only a significant threat as a source of human illness but also risks economy of the country (Makita et al. 2011). Present estimates of economic loss in meat and milk production resulting from Brucellosis are $800 million annually in the United States(OIE 2009). The incidence of the disease can be correlated to several factors including demographic and geographic factors(Soomro et al. 2014). Seroprevalence of the disease has been reported in different regions of Pakistan and ranges 3.25 to 4.4%(Naeem et al. 1990).
Brucellosis in cattle and buffaloes can be recognized clinically by an abortion usually occurring form 6 months and onwards i.e. last trimester of pregnancy (Soomro et al. 2014). Brucellosis is principally a disease of sexually mature animals as it affects mainly the reproductive system and fertility of the animals. It significantly reduces the survival rate of newborns and also the milk yield (Sikder et al. 2012). Greyish white mucoid or mucopurulent discharges from the vagina, prior to parturition of cow, may show the clinical patterns of disease along withnormal patterns of parturition like swelling of the vulva, relaxation of pelvic ligament, enlargement of udder and discharge from the vulva (Shafee et al. 2012).
Human infections as a result of Brucellosis range more than 500,000 annually round the world (Abo-Shehada and Abu-Halaweh 2011). Brucellosis can cause a wide range of symptoms similar to the flu and may also include fever (39-40°C), night sweats, headache, back pain and physical weakness. Severe form of infection may result in involvement of the central nervous system or the lining of the heart (Soomro et al. 2014). It is one of the principal public health problems for an agricultural country like Pakistan, where majority of the population is engaged in livestock farming (Shafee et al. 2012).
Brucellosis in humans is a severely debilitating condition that usually requires prolonged treatment involving a combination of strong antibiotics. The treatment results in permanent and disabling sequel, and also in significant medical expenses along with loss of income due to loss of working hours. Brucellosis can be transmitted to humans by ways of inhalation, direct contact with infected animals or contaminated products of conception and ingestion of unpasteurized dairy products and undercooked meat or meat products (Gwida et al. 2010; John et al. 2010). Brucellosis can also be transmitted from infected animals to human beings who are in close contact with animal secretions like infected vaginal secretions, blood, urine, feces, aborted fetus, or those who consume unpasteurized milk or other raw milk products. Shepherds, milkmen, butchers, knackers, veterinary assistants, and abattoir workers are at high risk (Agasthya et al. 2007)

An Epidemiological Investigation For The Selection Of Suitable Vaccine Virus Candidate Of Newcastle Disease
by Waqas Shabeer (2013-VA-920) | Dr. MUhammad Hassan Mushtaq | Dr. Muhammad Ali Abdullah Shah | Prof. Dr. Mansur ud Din Ahmed | Dr. Ali Ahmed Shaikh.
Material type: Publisher: 2015Dissertation note: The current study was designed to investigate the risk factors associated with Newcastle disease and characterization and confirmation of Newcastle disease on microbiological and molecular basis. Newcastle disease (ND) is one of the most important viral diseases. It is an acute infectious viral disease of domestic poultry and other species of birds regardless of variation in sex and age. Etiological agents of ND are virulent strains of avian paramyxovirus-1 genus Avulavirus, family Paramyxoviridae and order mononegavirales. The data collection was done on predesigned questionnaire. Newcastle disease virus isolation was done by using the embryonated eggs. Amnion allantoic fluid was harvested and checked for hemaglutinating activity by spot hemaglutinition test and results were recorded. For confirmation of NDV hemaglutinition assay and hemaglutinition inhibition test were used. Further confirmation was done by RT PCR using predesigned primers. Results showed that vaccine used at the most of farms were live attenuated. Most of the farms have no written biosecurity plan. A total of 264 samples were examined 17 samples were the best suspected positive for ND, 10 samples were confirmed on the basis of postmortem lesion, HI and PCR.
Conclusion:-
The study concludes the farm type, dead bird disposal, biosecurity, farm history and vehicles for feed transportation are the risk factors for the outbreak of Newcastle disease. Whereas water quality, farm mangers, litter disposal, vaccine schedule and vaccine type given at farm show no significant association with the spread of disease. The study characterized field isolates on microbiological and molecular basis, submitted to the principle investigator for use in development of multiepitop vaccine.

Publisher: 2016Dissertation note: The present study was designed to identify the association ofvarious risk factors with GDM.The study was consist of cases and controls andconducted for a period of 3 month i.e. February to April 2016. A total sample of 284 comprises of 142 cases and 142 controls were selected fromgynaecological outpatient department, tertiary care hospitalsof district Lahore. The cases matched on the basis of parity with control. The data about demographic and risk factors associated with gestational diabetes were collected through predesigned questionnaires.
The study was completed in a period of three months. The data was analyzed by using SPSS 16.0.The results of this study will be useful for the prevention and control of this disease from fatal outcome.
The results of the study showed the relationship of GDM among cases than controls. It was observed that most of the woman’s were illiterate and housewives. The economic status was found statistically significant in present study. But overall participants werefrom lower middle class families. Present study showed that the woman’s with the age of 29-35, that is high age group and significant association found in the mother age.
Previous history of diabetes mellitus and family history of diabetes mellitus also role plays in raising the prevalence of gestational diabetes mellitus. Gestational diabetes mellitus prevalence was higher in those women who had family history of diabetes. The higher number seen among cases who had diabetes in previous pregnancy, which was significantly higher at(p value= 0.000). It was investigated that diabetes mellitus was more common in high BMI>25kg/m2 so it has strong relationship with high BMI.
Conclusion
This study was designed to identify the risk factors associated with Gestational Diabetes Mellitus. Because the prevalence of Gestational diabetes is increasing with increase the number of women in childbearing age. The timely diagnosis of GDM and identify its risk factors are need of the time to control fetal and maternal complications.

by Rabia Saleem (2009-VA-460) | Dr. Muhammad Hassan Mushtaq | Dr. Mamoona Chaudhary | Dr. Arfan Ahmad.
Material type: ; Literary form:

Publisher: 2016Dissertation note: The term backyard chicken production designates poultry birds which are reared on small scale by a household. In this type of poultry rearing, usually a few birds are kept primarily for family use. The surplus birds and eggs are sold in the village or nearby market and the cash were utilized for fulfilling other needs of the household. This was a common practice in the rural area of all over the Pakistan.
Backyard poultry keepers are not well aware of management practices and poultry diseases. For that purpose nine rural areas were selected from Lahore by convenient sampling method. The households in each of the village were also conveniently select. 200 respondents were interview through a model questionnaire to assess knowledge about poultry diseases, zoonotic diseases and vaccination of poultry in backyard poultry keepers.
After compilation of the research data only 25.00% respondents know about poultry disease and only 48.74% use vaccination and medication for their birds if they got sick otherwise they never vaccinate or medicate.73.73% people do vaccination against New castle disease out of those who use vaccination/treatment but according to data they have no proper knowledge even New castle disease. 55.56% farmer observed diseases and sign and symptoms in their flock from which mites and ticks are 55.56%, respiratory sound and nasal discharge 44.45%, coughing, sneezing and greenish diarrhea 33.34%, swollen joints and ocular discharge 22.23%.Respiratory diseases are prevalent in that area.
70.00% people of the study have information about zoonotic diseases while only 26.00 people know about poultry zoonotic diseases. They are not properly educated about poultry zoonotic diseases
This study will help to collect the information about the knowledge of zoonotic disease, poultry disease and vaccination through survey from backyard poultry farmers. Results of the study are helpful to point out the main issue of poultry diseases and mortality. It is a need of hour to properly manage the back yard poultry on an early basis while a timed procedure should be developed to educate the rural farmers. Currently no proper regulatory body is working for the Poultry sector, PPA (Pakistan Poultry Association) working privately without any authoritative power. These points can be easily improved to help the poultry farmers in the sense of developing skillful backyard poultry producers to boost up poultry sector.
