Abstract
Background: Brucellosis in India is highly endemic in many states and reported as the most prevalent disease in dairy cattle. Brucellosis is a highly contagious bacterial disease caused by various Brucella species mainly affecting wide range of different species of animals like cattle, sheep, goat and pigs. The present study was undertaken to ascertain the prevalence of brucellosis in suspected buffalo population showing reproductive disorders in selected dairy farms residing nearby region of Hyderabad, Telangana. Methods: Total number of 204 vaginal swab samples were collected aseptically from suspected buffaloes in nearby private dairy farms and were screened by employing various diagnostic methods. Enzyme Linked Immuno Sorbent Assay (ELISA), Lateral Flow Assay (LFA) and molecular identification through Polymerase Chain Reaction (PCR) were conducted. The sensitivity of tests was recorded considering PCR as gold standard method. Result: Screening of 204 vaginal swab samples and prevalence of brucellosis were recorded by ensuring the positive reactions and also depicting the sensitivity of various diagnostic tests namely ELISA, LFA and PCR accounting 92(45.1%), 87 (42.64%) and 113(55.4%) samples respectively. The specificity of both LFA and ELISA were recorded 100% when compared to PCR assay.
