We examined by parasitological tests (hemoculturesandbuffycoat)infectionby Trypanosoma cruzi and T. evansi in blood samples from Leopardus pardalis, Cerdocyonthous and domestic dogs. Besides, 25 T. cruzi isolates previously derived from feral pigs and small wild mammals were here characterized by miniexon gene and demonstrated to be in the TcI genotype. Herein, we make an overall analysis ofthe transmission cycle of both try- panosome species in the light of the assemblage of data collected over the lasts evenyears. The carnivore Nasua nasua was confirmed to play a major role in thet ransmission cycles of both T. cruzi and T. evansi since it was the species that had the higher prevalence and higher parasitemias by both flagellat especies. Inaddition, our results show that bothtry- panosomatid species may be found through out the Pantanal landscape, in all forest strata, as shown by the infection of carnivore,arboreal and terrestrial scansorial marsupial species in complex and seasonal transmissioncycles. We propose that transmission of T. cruzi and T. evansi in the southern Pantanal region takes place via an intricate ecological trophicnet- work involving generalist and specialist mammal species that are linked through a robust food-web connection. |
