We studied the occurrence of anti-Leptospira spp. antibodies in captive rattlesnakes.
90% of the snakes were positive in the microscopic agglutination test.
Most frequent serovars were Javanica, Andamana and Patoc.
These snakes can present high titers despite the absence of clinical symptoms.
We focus on the importance of leptospirosis as an occupational zoonosis.
