Leptospirosis is a widespread and fatal zoonotic disease caused by Spirochaetes of the genus Leptospira. It constitutes a major public health concern in tropical and subtropical regions. Kerala is endemic for leptospirosis. It almost affects all the domestic and wild mammals as well as human beings causing severe renal and hepatic damage, leading to fatality, if untreated. The present study was conducted to analyse the seroprevalence of leptospirosis in animals in Thrissur district over a period of one year (March 2019 – March, 2020), based on the detection of anti-leptospiral antibodies using Microscopic Agglutination Test (MAT). A total of 205 serum samples (Dog-139, Cat-11, Cattle-29, Goat-26) collected from Teaching Veterinary Clinical Complex, College of Veterinary and Animal Sciences, Mannuthy and University Veterinary Hospital, Kokalai were analysed in the study. Among these samples, 43 were found to be positive (20.97 per cent) with MAT titre of 1:400. The seropositivity in dogs, cattle, goats and cats were 23.02, 20.68, 15.38 and 9.09 per cent, respectively. The most predominantserovar infecting dogs was identified as Leptospira interrogans serovar Australis and serovar Autumnalis. Cats and Cattle showed highest prevalence to serovar Sejore while goats showed prevalence to serovar Pomona followed by pyrogenes. From this study, we could conclude that there is a high prevalence of leptospirosis in the animal population in this district. For effective prevention of the disease, one must follow routine vaccination of pets, proper sanitation and waste disposal to control the rodent population that plays a major role in transmission of leptospirosis. The need for a modified vaccine for animals as well as humans including prevalent serovars of Leptospira is being highlighted.
