Detection of anti-Leptospira spp. agglutinins in captive South American river turtles, Podocnemis expansa
View through CrossRef
ABSTRACT Leptospirosis is a zoonosis transmitted by contact with infected urine or water contaminated with the agent. Searches for Leptospira spp. in reptiles are scarce although most species have contact with aquatic environments. We evaluated the presence of anti-Leptospira spp. antibodies in Podocnemis expansa housed at the Amazonian Zoobotanical Garden, in Belém, Pará state, Brazil. We analyzed 74 serum samples through the microscopic agglutination test using 31 live antigens from different Leptospira spp. serogroups. Thirty samples (40.5%) were positive against Leptospira spp., with titrations between 100 and 3,200 for one or more serogroups. The Hebdomadis serogroup was the most prevalent, with 26 (87%) out of the 30 positive samples, followed by Djasiman, with two (7%) and Celledoni and Bataviae with one (3%) sample each. The detection of anti-Leptospira spp. agglutinins in P. expansa suggests that the aquatic environment is a transmission route for this pathogen among chelonians.
