| Abstract | Introduction: Panstrongylus megistus is commonly found in wild environments of the State of Rio Grande do Sul, Brazil.
The aim of this study was to characterize the network of refuges used by triatomine in a forest fragment of Porto Alegre and
to identify Trypanosoma cruzi infection, associated hosts and the epidemiological importance of both hosts and triatomines.
Methods: Techniques including the spool-and-line method and active searching (transects) were used to identify natural foci.
Results: The food source for each triatomine was determined using the precipitin test, and the infection of marsupials was
determined by xenodiagnosis. A total of 33 adults (domestic environment) and 27 nymphs (wild environment) of P. megistus
were found in addition to 43 Didelphis albiventris specimens. The infection rates of triatomine adults, triatomine nymphs and
opossums with T. cruzi I were 64%, 73% and 69%, respectively. Birds, rodents and opossums were the main resources used by
triatomine. Conclusions: This work presents the fi rst characterization of a natural focus of P. megistus in Rio Grande do Sul. The
natural characteristics of this focus and its implication in the transmission of T. cruzi are discussed. | pt_BR |
