One of the economically important zoonotic diseases of livestock in the world is leptospirosis and is caused by infection with the spirochete Leptospira. Animals in an organized farm in Thanjavur district of Tamilnadu were selected for the present study which has shown the symptoms of renal failure, midterm abortion and loss of milk production. The microscopic agglutination test (MAT) is the most commonly used technique for diagnosing leptospirosis in these animals. Battery of leptospira antigens used in this study was Icterohaemorrhagiae, Canicola, Grippotyphosa, Hebdomalis, Pomana, Autumalis, Pyrogens, Tarassovi, Ballus, Javanica, Australis and Hardjo. Reacting serovars presented in different animals were Ballum, Hardjo, Hebdomadis, Javanica and icterohaemorrhagiae. Detection of high titers of antibody in animals with a disease consistent with leptospirosis may be sufficient to establish the diagnosis. This is particularly true in this investigation, in which 10 out of 6 samples showed agglutinating antibody titer of >800. Biosecurity measures were improved in the farm along with combination of treatments to efficiently bring the infection under control in a herd infected with serovar Hardjo. The study indicated a high level of the prevalence of leptospirosis in animals, warranting continuous investigations in order to suggest control strategies in the future.
