ABSTRACT.- Almeida D.S, Santos A.C., Silva C.L.R., Oriá A.P., Oliveira A.V.D., Libório F.A., Athanazio D.A. & Pinna M.H. 2016. Evidence of leptospiral exposure in neotropical primates rescued from illegal trade and a Zoo in Bahia, Brazil. Pesquisa Veterinária Brasileira 36(9):864-868. Departamento de Patologia e Medicina Legal, Praça XV de Novembro s/n, Largo do Terreiro de Jesus, Salvador, BA 40025-010, Brazil. E-mail: daa@ufba.br Few studies have compared the seroprevalence of antileptospiral agglutinins with the demonstration of urinary shedding of leptospires or evidence of active infection in the bloodstreams of non-human primates. The study population consists of 58 animals, including d 42 monkeys from the Zoological Park of Salvador (Parque Zoobotânico Getúlio Vargas), Bahia, Brazil. The study also evaluated 16 primates (Cebus sp.) rescued from illegal trade that were housed in the Wildlife Rehabilitation Center of Salvador (CETAS), Bahia, Brazil. The seroprevalence of antileptospiral antibodies was low (2%) in the animals from the Zoo. A higher rate (31%) was observed among the animals that were rescued from illegal trade in the state of Bahia. Even if all the blood and urine samples were negative for leptospiral DNA fragments, the high frequency of serological evidence of exposure suggests a potential risk of leptospirosis transmission when keeping these animals as pets.

RESUMO.- Almeida D.S, Santos A.C., Silva C.L.R., Oriá A.P., Oliveira A.V.D., Libório F.A., Athanazio D.A. & Pinna M.H. 2016. Evidence of leptospiral exposure in neotropical primates rescued from illegal trade and a Zoo in Bahia, Brazil. [Indícios de exposição a leptospiras em primatas neotropicais resgatados do comércio ilegal e de um Zoológico da Bahia.] Pesquisa Veterinária Brasileira 36(9):864-868. Departamento de Patologia e Medicina Legal, Praça XV de Novembro s/n, Largo do Terreiro de Jesus, Salvador, BA 40025-010, Brazil. E-mail: daa@ufba.br Poucos estudos compararam a soroprevalência de aglutininas antileptospira com a demonstração de excreção urinária de leptospiras ou evidência de infecção ativa em primatas não humanos. A população estudada consistiu em 58 animais, sendo 42 primatas do Parque Zoobotânico Getúlio Vargas, Bahia, Brasil. O estudo avaliou ainda 16 primatas (Cebus sp.) resgatados do tráfico ilegal e abrigados no Centro de Triagem de Animais Silvestres Chico Mendes, Salvador, Bahia, Brasil. A soroprevalência de anticorpos antileptospira foi baixa (2%) nos animais do Zoológico. Uma taxa mais elevada (31%) foi observada nos animais resgatados do tráfico ilegal. Mesmo que todas as amostras de sangue e urina tenham sido negativas para DNA de leptospiras, a alta frequência de evidência de exposição nos animais de origem selvagem indicam o risco potencial da adoção de primatas como animais de estimação.

ABSTRACT.- Silva E.F., Seyffert N., Jouglard S.D.D., Athanazio D.A., Dellagostin O.A. & Brod C.S. 2009. [Seroprevalence of leptospiral infection in capybaras (Hydrochoerus hydrochaeris) in a slaughterhouse of Rio Grande do Sul, Brazil.] Soroprevalência da infecção leptospiral em capivaras (Hydrochoerus hydrochaeris) abatidas em um frigorífico do Rio Grande do Sul. Pesquisa Veterinária Brasileira 29(8):174-176. Laboratório do Centro de Controle de Zoonoses, Faculdade de Veterinária, Universidade Federal de Pelotas, 96010-900 Pelotas, RS, Brazil. E-mail: efsilva@ufpel.edu.br 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.
