RESUMEN
Capybaras (Hidrochoeris hidrochoeris) are 1 of the largest rodents used for meat in South and Central America. Prevalence of anti-Toxoplasma gondii antibodies in 149 feral H. hidrochoeris from the state of São Paulo, Brazil, was evaluated using the indirect immunofluorescent antibody test (IFAT) and the modified agglutination test (MAT). Using IFAT, antibodies (>1:16) were found in 104 (69.8%) and with the MAT, antibodies (>1:25) were found in 63 (42.3%) capybaras. This is the first report of prevalence of T. gondii antibodies in this host.

During previous research on phlebotomine fauna in a settlement of the Brazilian National Agrarian Reform Institute (INCRA) on the Bodoquena Range, Mato Grosso do Sul State, Brazil, dogs were observed with clinical aspects suggestive of visceral leishmaniasis. A serological survey to leishmaniasis in 97 dogs, by indirect immunofluorescence test, showed 23 (23.7%) serum positive dogs. Samples of the parasites were identified as Leishmania (Leishmania) chagasi.

A serological survey was made in 973 stray dogs caught near green areas in S. Paulo county by the indirect immunofluorescence test. No positive serum was found, however autochthonous human cases of ACL that occurred in the county show the circulation of the parasite in the environment. This fact, associated with the existence of the vectors and the apparent absence of infected dogs in the areas studied, suggest that stray dog plays an insignificant role in the spread of the parasite. The cycle of the parasite in São Paulo county has been maintained by wild animals, hence the dog would be an accidental host just as humans.

Durante estudos sobre a fauna flebotomínea em assentamento do Instituto Nacional de Reforma Agrária (INCRA) na Serra da Bodoquena, Estado de Mato Grosso do Sul, Brasil, foram observados cães com manifestações clínicas sugestivas de leishmaniose visceral. Inquérito sorológico para leishmaniose em 97 cães, utilizando reação de imunofluorescência indireta, mostrou 23 (23,7%) soros reagentes. Amostras do parasita foram identificadas como Leishmania (Leishmania) chagasi.
