| Abstract | Trypanosoma cruzi is a widespread protozoan in Latin America causing Chagas disease in humans and able to
infect several other mammal species. The objective of this study was to investigate the T. cruzi infection in
triatomine fauna as well as in dogs from distinct areas of Acre, western Brazilian Amazonia, which recently
reported acute cases of human CD as well as an area that have not notify this disease recently. Triatomines were
collected and the intestinal contents were evaluated for the presence of trypanosomatids by optical microscopy
and polymerase chain reaction (PCR) targeting the mini-exon gene. Blood smear, hemoculture, PCR and serology
were performed in the studied mammals. Fecal content of four triatomines were positive (11.6%) in the fresh
examination. Molecular analysis identified Trypanosoma cruzi TCI in two specimens. Blood samples from 90 dogs
were obtained. Trypanosoma sp. was observed in six blood smears (6/83, 7.22%). Seropositivity for T. cruzi was
8/89 (8.98). One dog's hemoculture was obtained and characterized as T. rangeli. PCR reactions in blood clots
resulted in one positive dog (1/75, 1.3%) infected by T. janseni, providing a new mammalian host for a recently
described Trypanosoma species. The results demonstrate the low exposition and prevalence for T. cruzi suggesting
that dogs are not important to T. cruzi transmission cycle in the studied áreas. | pt_BR |
