| Abstract | |
Anthropogenic environmental changes are the main factors of emergence or reemergence of infectious diseases. Cutaneous leishmaniasis is a disease that is related, in an epidemic form, with episodes of deforestation. However, the endemicity of the disease occurs when the man is close to forest areas already colonized. The Pontal of Paranapanema is an area where massive deforestation has occurred and the remaining native forest is represented by the Morro do Diabo State Park and a few forest fragments. Cases of cutaneous leishmaniasis in humans are common in the region, especially in marginal areas of forest. The aim of this study was a survey of sand flies and mammals potentially reservoirs, in Morro do Diabo State Park and some fragments of the region, seeking to assess whether the fragment size has an influence on species occurrence and frequency of Leishmania, through the PCR technique. We captured 26 species of sandflies and seven species of wild mammals. The genus Brumptomyia was prevalent in almost all forest areas, except the edge of the park, which showed dominance of Nyssomyia neivai. The results of PCR analysis revealed four species of mammals suffering from Leishmania, Akodon cursor, Dasyprocta azarae, Didelphis albiventris and Oligoryzomys sp. Samples of sandfly pools tested negative. There was no significant difference in the frequency of infected mammals in relation to the size of the forest. (AU) | |
