Abstract

Visceral leishmaniasis (VL) has been a widespread zoonosis in São Paulo since 1998, when the first autochthonous canine case was identified in Araçatuba. The aim of this study was to determine the occurrence of anti-Leishmania infantum syn chagasi antibodies in serum samples of 584 dogs from São José do Rio Preto, São Paulo, a non endemic area for the disease. Five dogs (0.86%) seroconverted by ELISA and one (0.17%) by immunochromatography. The indirect immunofluorescent reaction, carried out in 138 animals whose optical densities were above or close to ELISA's cutt-off point, evidenced two dogs (1.45%) with titers above 1:40. Only one dog was serum-reactive on the three techniques. Although there was not a history of displacing this animal to endemic areas, the dog had been acquired in a region with canine and human cases of VL. These results suggests that there were no autochthonous cases of canine VL in this population.
