Serological survey was carried out in order to investigate the seroprevalence of leptospirosis in ruminants in coastal regions (flood prone areas) of endemic states (Andhra Pradesh, Gujarat, Kerala, Maharashtra and Tamil Nadu) of India using non-purposive samples collected during the year 2011 and 2012. A total of 553 serum samples (Cattle-332; Buffaloes-85; Goats-107 and Sheep-29) collected randomly from twenty one coastal districts of five states were tested at 1 in 100 dilution in microscopic agglutination test using 14 reference leptospira serovars. The overall seroprevalence of 24.96 (138/553) with 20.48 in cattle, 20 in buffaloes, 58.62 in sheep and 38.3 in goats was observed. The results of χ2 tests revealed that the seroprevalance in cattle across different districts (regions) in each of the surveyed states are not associated except in Kerala (χ2 = 33.98, p < 0.05). In other species (buffalo, sheep and goat) also there is no association of seroprevalance across different districts in each of the states. Among the targeted endemic states, high prevalence was observed in Maharashtra (19/53 = 35.85 ) followed by Kerala (52/165 = 31.51 ), Andhra Pradesh (16/50 = 32 ), Gujarat (48/212 = 22.64 ) and Tamil Nadu (3/72 = 4.17 ). Out of 138 reacted sera, 37 samples showed multiple reactivities with 26.81 prevalence. The predominant leptospiral antibodies were determined against frequency of distribution of the serovars Hardjo (28.99 ) followed by Kaup (18.12 ), Pomona (15.94 ), Bankinang (14.49 ). This study supports that ruminants may have a role in maintaining intermediate species serovar Kaup apart from being a well-known reservoir for Hardjo serovar in endemic states of India.
