Capybaras (Hydrochoerus hydrochaeris) are wild rodents from the American Continent with increasing importance as a commercial alternative source of meat for human consumption. Studies on seroprevalence for leptospiral infection are scarce and restricted to free living capybaras. We report detection of agglutinating antibodies against leptospires in 27% (6/22) of all animals in a slaughterhouse from Rio Grande do Sul. The highest antibody titers predicted Australis as the infecting serogroup due to reactions against a reference strain of serovar Bratislava and a canine local isolate of serovar Australis, characterized as Leptospira noguchii. The data presented in this report highlight that a considerable fraction of capybaras in captivity may behave as reservoir for pathogenic leptospires emphasizing the occupational risk of those who deal with animal farming and slaughter. |
