Abstract

Leishmaniasis is a zoonotic disease transmitted by sandflies of the subfamily Phlebotominae, whose etiologic agent is the protozoan Leishmania spp. A clear process of urbanization of visceral leishmaniasis has been observed, although this is primarily wild and man is an accidental host. The city of Campinas, State of São Paulo has epidemiological situation of municipality with canine transmission since 2009. In this year, it was registered the first autochthonous case of canine visceral leishmaniasis in a condominium located in the Environmental Protection Area (APA), highlighting the need for epidemiological research and surveillance actions. This study aims to assess the presence of Leishmania chagasi infections in free-ranging wild mammals from the APA of Campinas, through capture and blood collection every two months, for one year. Seroepidemiological survey will be carried out by assessing and quantifying anti-Leishmania spp. antibodies, using the Direct Agglutination Test (DAT) and Fast Immunoassay (Kalazar-detect"), and DNA detection of Leishmania spp., and L. chagasi by the technique of Polymerase Chain Reaction (PCR). Thus, we aimed to obtain information as to infection by L. chagasi in mammals from the APA of Campinas and the possible occurrence of a sylvatic cycle of AVL in the region. We expect to achieve results that contribute to the elucidation of the exact mechanisms of transmission and the introduction of the disease in the region. (AU)
