Publisher: 2013Dissertation note: Foot and mouth disease (FMD) is highly infectious disease of cattle, buffalo, sheep and goats. It is caused by genus Aphthovirus of Picornaviradae family. FMDV is RNA virus having seven serotypes A, O, C, Asia 1, SAT1, SAT2 and SAT3.
Serotypes A, O, C and Asia1 are endemic in Pakistan and causes high economic losses to livestock industry .So priority is to apply quick and efficient methods for detection of FMDV infection and to limit the spread of outbreaks of the disease. Although CFT, VNT and ELISA are already being used for the diagnosis of FMDV in Pakistan but these diagnostic techniques are time consuming and their specificity and sensitivity is low. RT-PCR for the identification of FMDV is very much sensitive and specific, can be done within three hours after receiving of samples to the laboratory.
Foot and mouth disease (FMD) in adult sheep and goats is frequently mild or unapparent, but can cause high mortality in young animals. The outbreaks of FMD in 1999 in Morocco, in 2001 in the United Kingdom & in 2007 in Cyprus has highlighted the importance of sheep in the epidemiology of the disease, although there have been numerous examples in the past where small ruminants have been responsible for the introduction of FMD into previously disease-free countries. The difficulty in making a clinical diagnosis should encourage the development of more rapid screening tests to assist in future control programs.
In Pakistan, no study has been conducted to depict the role of small ruminants in the epidemiology and transmission of FMD virus to the large ruminants. Keeping in view this neglected area of research, present study is planned to apply the sensitive and economical RT-PCR technique for the rapid detection of carrier status of FMD virus in ruminants; and to highlight the importance and need of vaccination to small ruminants against FMD virus in order to control outbreaks of the disease and transmission to the large ruminants population.

Publisher: 2013Dissertation note: The poultry sector is one of the most systematized and vibrant divisions of the agriculture industry of Pakistan. The poultry sector has shown a vigorous growth of 8 to 10 percent annually, which reveals its distinctive potentialNewcastle disease, is an acute, contagious rapidly spreading viral disease of domestic poultry and wild bird of all ages with mortality up to 100% in the infected flocks. It is caused by avian Paramyxovirus serotype-I. This disease is major restraint to attain acceptable production levels in commercial broiler. In Pakistan ND is commonly reported disease in both vaccinated and non-vaccinated flocks.
In the current study risk factors which were associated with the outbreak of Newcastle Disease regarding farm practices were identified and recommendations can be given for the control of ND on the basis of comparing current and previous (2011-2012) farm practices in environmentally controlled commercial broiler houses.
The results of this study are applicable on all the commercial broiler population which is being reared in environmentally controlled houses in Lahore District.Number of environmentally controlled houses was 128 environmentally control sheds in Lahore District. But only 96 farm managers guven consent for the visit of their farm so the sample was n= 96 environmentally controlled houses. Sampling unit was one environmentally controlled house. A questionnaire was developed about the risk factors which were considered to be associated with ND outbreak. A total n= 96 Environmentally controlled houses of commercial broiler affected and not affected by the ND outbreaks in and around Lahore District were selected with the help of convenient sampling method and their owner/manager were interviewed face to face and information was also collected from the farm record. Out of 96 ECH(Environmentally Controlled Houses) of commercial broiler 79 suffered from newcastle disease outbreak while only 17 ECH were non-infected during period of 2011-2012.
Data were analyzed using SPSS version 20 and odds ratio was calculated for the studied and supposed risk factors. Distance between farms less than 5Km, feed transporting vehicle, method of dead infected birds' disposal and type of labor on the farms were found as risk factors for the newcastle disease out breaks. Water quality, biosecurity, feed storage method, heat source used, farms managers, litter disposal methods showed a negative association with the spread of disease. E. coli and salmonella infection were mostly observed as secondary infections among the ND affected flocks. Avian influenza showed an association with newcastle disease. Infectious bursal disease and hydro pericardium syndrome showed no association with ND epidemics.

Publisher: 2015Dissertation note: In the review by O’Reiley and his colleagues, Tuberculosis has been defined as a disease that affects the respiratory system foremost and its route of transmission from one animal species to another is by the airborne route along with consumption of un-pasteurized milk (O'Reilly, 1995) (De la Rua-Domenech, 2006) (Thoen et al. 2006). The review states that Mycobacteriumbovis causes tuberculosis in bovines as well as a number of wild animals such as goats, cats, dogs, pigs, buffalo, badgers, possums, deer, bison and non-human primates but most importantly it causes tuberculosis in humans. This makes the disease of significant public health importance due to its zoonotic nature.
The study was conducted in two of the largest dairy colonies in Lahore- Rakhchandra and Harbanspura dairy colony. 400 dairy animals (lactating) were selected from the target areas. 200 animals per field were chosen through convenience sampling. The research was divided into two parts. Phase 1 was concerned with screening of animals for bovine tuberculosis through performance of comparative intradermal tuberculin test (CIDTT) and followed by culturing of milk samples from animals that came positive. Phase 2 was concerned with testing of all human subjects who were in contact with the positively screened livestock. Since none of the human subjects showed any of the signs for tuberculosis, no testing of the humans could be performed.
The first step to animal testing was concerned with the screening of selected animals with comparative cervical intradermal tuberculin test (CIDTT). This involved the intradermal injection of bovine tuberculin purified protein derivative (PPD) and the subsequent detection of swelling (delayed hypersensitivity) at the site of injection 72 hours later (Anonyms, 2008a). The test was considered positive if the difference between the swellings on the two sites was more than 4mm and it was the mammalian site that showed more swelling. Once the results were read, the dairy farmers were asked a set of questions designed to identify risk-factors for zoonotic tuberculosis. The farmers responded to nearly all the questions that were posed to them.
Milk sample was collected from the animals that tested positive. 50 ml of milk was collected from the positive animals. Once collected, the milk bottles were quickly capped and labeled and put in the ice-box before being transported to Provincial Tuberculosis Reference Laboratory in Lahore. Staining followed by culturing of milk samples for the isolation of Mycobacterium bovis was then proceeded with. For the purpose of culturing two types of media were prepared before-hand-Lowenstein Jensen (LJ) media and LJ-pyruvate media. LJ medium allows the growth of Mycobacterium tuberculosis, whereas LJ with pyruvate medium allows the growth of Mycobacterium bovis.
Petroff’s method was employed for the processing of milk samples which originally is used for sputum processing (Anonyms, 2009). The process was altered to suit our requirements. Once processed 300ul of pipette tips were used to place 100ul of processed sample on pre-marked slides for ziehl-neelson staining and 120ul on pre-made media slants a total of 4 bottles, 2 each of LJ media and LJ pyruvate media for duplication of results and to act as control. The bottles were checked for growth every week on Monday till 8 weeks of time.
At Rakhchandra dairy colony the tuberculin test done on 200 animals revealed only three (3) positive animals. Thus the prevalence of TB in Rakhchandra came out to be 1.5%. Out of 200 animals in Harbanspura dairy colony, six (6) animals showed hypersensitivity reaction and were positive. Prevalence of TB in Harbanspura came out to be 3%. Out of 400 animals tested, 90 were cattle and 310 were buffaloes. Only buffaloes showed hypersensitivity reaction to tuberculin. None of the cows tested came out to be tuberculin positive. In this particular study, the prevalence of TB on the basis of tuberculin test in buffalo was 2.9% where as in cattle it was 0%. When milk was collected and processed from the above mentioned nine (9) animals, the results showed a different picture. None of the cultures showed any signs of growth by 8 weeks of incubation. All nine milk samples after cleaning were stained by ZN staining and observed under microscope for the presence of mycobacterium, none came out positive.
The Basic Health Units (BHU) in each of the colony were contacted and it was found that in the last 10 years less than 10 patients who were suspected to have tuberculosis were referred to District Health Quarter (DHQ).
Even though a higher percentage (44.44%) of farmers in Harbanspura was recorded to have some knowledge about the zoonotic aspect of tuberculosis as compare to those in Rakhchandra (22.22%), yet a higher number of tuberculin positive animals was found in Harbanspura (6 versus 3). The economic status of farmers in Harbanspura was comparatively higher with 33.33% of farmers earning more than 1 lakh rupees per month, whereas in Rakhchandra this figure stood at 27.78%. This might be a mere chance of co-incidence but it also implies the unwillingness of farmers to apply biosecurity measures at their farms. Lack of willingness to take such precautionary steps places the farmers and their animals in great peril, since in the last six months alone 66.67% of the farmers in Harbanspura had purchased at least one animal, which is enough to bring disease in an un-infected herd. Only 27.78% of farmers in Rakhchandra had purchased animals on the other hand. Also only 77.78% of farmers in Harbanspura would clean the dung from the farms twice a day whereas 100% Rakhchandra farmers would cleanup twice a day. The tuberculin positive animals were found to be spending most time of their day in filthy places. Their sheds were not cleaned regularly. Heaps of dung and ground wet with urine was observed on every visit. It exposed animals to numerous infections and 11.11% of animals in Harbanspura and 44.44% of animals in Rakhchandra were suffering from unidentified chronic illnesses. Farmers said that they preferred to sell such animals to butchers (85.8% combined percentage), rather than burying after culling (3.7% combined percentage). Deworming was not considered a mode of disease prevention amongst the farmers since only 22.22% of all farmers bothered to deworm their animals. The animals were seen to not having a score of above 2.5 when their body scoring was done (Scale 1-5). The one blissful factor discovered was the habit of nearly all farmers (92.59%) preferred to boil milk before consumption. Even dairy products were made from boiled milk (81.48%). This single factor could be the reason why the farmers consuming otherwise contaminated milk was still in such a glowing healthy condition.
The study allowed us to get a measure of the status of disease in lactating animals and to investigate the conditions that prevail in the two dairy colonies. It showed a difference in the prevalence of disease in Harbanspura and Rakhchandra famous for providing milk to Lahore city. This was scrutinized through a detailed analysis of farmer habits and environment of animals in both the fields. This study would permit upcoming researchers to have an up-to-date status of tuberculosis in the dairy colonies.
