Abstract

The global population growth, associated with the environmental fragmentation and degradation,and the increasing proximity between human communities, livestock and wildlife lead to destabilization of trophic chains and consequent rise of emerging diseases. More than 75% of emerging zoonotic pathogens of humans has originated in wild animals. Carnivores have vital importance to the integrity and stability of their ecosystems, especially because they act controlling the population of species in lower levels of the trophic chain. In the Iguaçu National Park, the coatis and graxains are common species of generalist and opportunistic carnivores, with wide distribution in the territory of the park. As generalists, they benefit from human influence, approaching human populations and becoming vulnerable to domestic animal pathogens, and can adduce pathogens to livestock and humans. Recently we diagnosed the presence of filarids with zoonotic potential in the park area, as well as confirmation of autochthonous cases of canine visceral leishmaniasis in domestic dogs in this region. Thus, because of the importance to the public health as well a complementary tool in the conservation of local wildlife, this research aims to study filarioses and Leishmania chagasi in generalist carnivores in Parna Iguaçu, to try understand the host-parasite relationship and the ecological processes that may favor the transmission of these agents among wild populations, domestic and humans.
