ArticleItem Open Access CROSS-SECTIONAL SEROSURVEY ON BOVINE BRUCELLOSIS IN CATTLE AND ITS EPIDEMIOLOGICAL SIGNIFICANCE IN INTEGRATED ORGANISED FARMS(Indian Veterinary Association Kerala, 2015-11) Preena, P.; Balakrishnan, S.; Ganesan, P.I.; Vijayabharathi, M.; Shereef, Shefeena; Kumar, V. Naveen; TANUVASBrucellosis in bovines is mainly caused by Brucella abortus inflicting late term abortion and in- fertility. Infected cattle act as a main source for transmission to other animals, animal handlers and veterinarians as an occupational hazard under organized farming system. Eventhough most Brucella species has host specificity, crossing of animal host boundary is likely to occur any time in swine, sheep and goat. The serosurveillance of animal health status has to be strictly regulated for effective control of brucellosis in integrated farms. The aim of this study was to determine the apparent prevalence of brucellosis in bovine from various organized farms in Tamil Nadu using ELISA. It was found that 21.35% of the cattle screened for brucellosis were positive for anti-Brucella abortus antibodies which may definitely have an impact on cross species transmission of brucellosis. Brucellosis being endemic in India, the effective control of brucellosis in all farm animals through vaccination programme and strict seroconversion studies is essential.ArticleItem Open Access Epidemiological Studies on Prevalence of Gastrointestinal Parasites in Cattle(Indian Veterinary Journal, 2017-09) Bharathi, M.

Naveen; Bharathi, M. Vijaya; Porteen, K; TANUVASA total of 483 cattle milk samples were collected in 11 districts of Tamil Nadu and were subjected to Milk Ring Test (MRT) and milk Enzyme Linked Immunosorbent Assay (m-ELISA) and reported 4.35 and 5.80 % of brucellosis respectively. Using m-ELISA as gold standard, MRT showed sensitivity, specificity and kappa value of 53.57%, 98.68% and moderate agreement (0.59) respectively. This study concludes that, MRT can be used as field level screening test in the diagnosis of bovine brucellosis.OtherItem Open Access Incidence of Endoparasites in Donkeys from Coimbatore(TANUVAS, 2016-02) Sowmiya, M.; Kumar, V.

Naveen; Jayathangaraj, M.G.; Vedamanickam, Stalin; Gopal, Sathish; TANUVASLittle is known about gastrointestinal parasite infections in wild ruminants. Faecal survey of parasitic prevalence plays an important role in wildlife management. The Wildlife interface regions, adjoining regions of forests serve as potential marker zones that serve to intermediate buffer zones that provide the viable ecology for the transit of various parasites between domestic and wild animals sharing the same landscape. Parasitic infections can cause disease and death in wild animals and can become a source of infection for domestic animals. Epidemiological studies are important to know about the status and transmission of these diseases. Parasitic diseases are best controlled by preventing the contact and parasite transmission between wild and domestic animals and by manipulating the factors involved in the disease transmission. The aim of this paper was to find out the prevalence of gastrointestinal parasites in gaur (bos gaurus) and domestic cattle at interface zones of the nilgiri hills. Qualitative examination of faecal samples from wild gaur (n=30) sharing ecosystem with domestic cattle (n=20) in the Nilgiri hills was done by Centrifugal sedimentation method and Floatation method. The prevalence was 63.3% and 80.0% in wild gaur and domestic cattle respectively with overall prevalence of 70.0%. The helminthes observed were trematodes (13.3%) include Fasciola sp. (3.3%), Amphistome sp. (6.7%) and Schistosoma sp. (3.3%), cestodes (20.0%) include Moniezia sp. nematodes (43.3%) include Toxocara sp. (6.7%), Strongyle sp. (23.3%), Oesophagostomum sp. (3.3%), Trichuris sp. (6.7%) and Mecistocirrus sp. (3.3%) and unsporulated Coccidia oocysts (13.3%) in wild gaur. It was concluded that, parasitic prevalence survey is vital in monitoring the impact on the health and maintenance of wild gaur population, and the prevalence of GI parasites recorded in the wild gaur and domestic cattle in the study areas shows the need to design and implement a control policy of helminth parasites in the Nilgiri hills.OtherItem Open Access Prevalence of Haemoprotozoan Diseases in Cattle and the Influence of Season, Age and Breed(TANUVAS, 2016-02) Bharathi, M. Vijaya; Kumar, V. Naveen; Sowmiya, M.; Sekar, M.ArticleItem Open Access Risk Factors Associated with Prevalence of Bovine Brucellosis in Milk from Tamil Nadu, India(Int. J. Curr. Microbiology and Applied Sciences, 2017) Kumar, V. Naveen; Bharathi, M. Vijaya; Porteen, K.; TANUVASBrucellosis is a contagious and reproductive disease of animals mainly caused by Brucella abortus, B. melitensis, B. suis and B. canis. Diagnosis and identification of associated risk factors in brucellosis is important in devising an effective control strategy. This study is mainly focused to find out the prevalence and assessment of risk factors in lactating cows for bovine brucellosis from eleven districts of Tamil Nadu. A total of 483 milk samples were collected and subjected into Milk Ring Test (MRT) and milk Enzymatic Linked Immunosorbent Assay (m-ELISA), which revealed that 4.35 and 5.80 per cent of the samples were found to be positive by MRT and m-ELISA respectively. Various epidemiological determinants viz., age, breed and clinical history correlation with prevalence rate were assessed. Crossbred cattle, cattle with more than seven years of age and aborted history animals have recorded more prevalence of brucellosis. This manuscript concludes that routine screening, proper diagnosis and correction of identified risk factors will be more useful in devising appropriate disease control programme from the study area.ArticleItem Open Access Serological Studies on Bovine Brucellosis of Tamil Nadu(Indian Veterinary Journal, 2017-09) Kumar, V. Naveen; Bharathi, M. Vijaya; Porteen, K.; Sekar, M.; TANUVASSero surveillance cross sectional study was carried out to assess bovine brucellosis from eleven districts of Tamil Nadu. Out of 821 serum, the highest seroprevalence of brucellosis was detected by i-ELISA (6.70 %) followed by STAT (4.38%) and RBT (4.02%). Comparatively, i-ELISA is the most suitable test for diagnosis of bovine brucellosisArticleItem Open Access கழுதைகளில் அக ஒட்டுண்ணிகளின் நிகழ்வுப் பதிவு(Veelan ariviyal tamil iyakkam, Newdelhi, 2016) Sowmiya, M.; Kumar, V.
