Abstract

The present study was aimed to report the positive prevalence of Leptospira strains in and around Chennai. The dogs presented to Madras Veterinary College Teaching Hospital from January 2023 to December 2023 were included for this retrospective study. Overall positive prevalence of canine leptospirosis was 41.17 per cent (42/102) based on microscopic agglutination test (MAT). Canine leptospirosis was found to be higher in the age group of 1year to 5years. Positive prevalence was higher in male dogs than female in canine leptospirosis. Leptospirosis strains included in vaccine are Canicola, Pomona, Icterohaemorrhagiae and Grippotyphosa. The unvaccinated strains including Autumnalis, Australis, ballum were highly prevalent among dogs and less prevalent strains were Pyrogenes, Javonica and Hebdomadis.
