Brucellosis 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.
