Leptospirosis, a disease that occurs worldwide, especially in tropical regions, is caused by bacteria of the genus Leptospira and affects mammals, amphibians, and reptiles. Boa constrictor snakes are commonly found in Atlantic rainforest fragments in peri-urban areas, which indicates a greater possibility of the contact of these animals with humans residing there. Therefore, the aim of this work was to detect Leptospira spp infection through molecular assays in wild B. constrictor snakes rescued in peri-urban areas and verify seroreactivity, by the microscopic agglutination test (MAT), as well as the most common serogroups. Among the 46 samples tested, 7 (15.21%) were positive according to PCR and confirmed as Leptospira interrogans through secY gene sequencing. In MAT, 37 (80.43%) of the 46 samples were classified as reactive. Panama was the serogroup with the highest occurrence. The results showed the presence of Leptospira spp DNA in asymptomatic snakes rescued in rainforest fragments located in peri-urban areas and support further investigations on the influence of these animals in the epidemiology of leptospirosis in tropical peri-urban areas.
