The Amazonian manatee (Trichechus inunguis) is an aquatic mammal (Family Trichechidae) that inhabits freshwater environments. It is endemic to the Amazon Basin, and occurs from Marajó Island (at the mouth of the Amazon River in Brazil) to the headwaters of the floodplain in Colombia, Peru and Ecuador. Little is known of the causes of death or the prevalence of zoonotic organisms in manatees from Peru; however, Leptospira spp. have been reported to cause mortalities in marine mammals. Here we evaluated the presence of Leptospira spp. antibodies in Amazonian manatees. To our knowledge, this is the first report of presence of antibodies against Leptospira spp. in aquatic mammals maintained in captivity in the Peruvian Amazon.
