Leptospirosis is an economically important zoonotic bacterial disease of cattle with global distribution. The present study investigated the seroprevalence and distribution of leptospiral serovars in cattle population in Pananchery panchayat of Thrissur district, Kerala. From 52 apparently healthy dairy cattle, serum samples were collected in both pre-monsoon and postmonsoon seasons. All samples were subjected to microscopic agglutination test (MAT) against 13 serovars of Leptospira spp. Among the samples tested, 13 (25 per cent) samples in pre-monsoon and 19 (36.54 per cent) samples in post-monsoon were found to be positive. The predominant serovars detected in pre-monsoon were Hardjo (29.41 per cent) followed by Grippotyphosa (17.64 per cent), Bataviae and Pomona (11.76 per cent each). Similarly in post-monsoon, Hardjo (28.57 per cent) followed by Grippotyphosa (23.81 per cent), and Bataviae (19.05 per cent) were identified as the most common serovars. Higher seroprevalence of disease in apparently healthy cattle in post-monsoon compared to pre-monsoon indicate the influence of rainfall on occurrence of leptospirosis.
