Methods: We collected specimens from a residence in the municipality of Rorainópolis. Results: Our findings confirmed the occurrence of this species in Roraima, increasing the number of registered species from six to seven. Conclusions: Future studies are required to further investigate and expand our knowledge of the occurrence of this species and its epidemiological importance for this state.
RESUMO
Abstract Chagas disease is caused by the protozoan Trypanosoma cruzi. Seven lineages have been identified based on different molecular markers, namely TcI, TcII, TcIII, TcIV, TcV, TcVI, and TcBat. Dogs play the role of epidemiological sentinels being domestic reservoirs of T. cruzi. The aim of the current study was to report the first case of CD in a domestic dog in Manaus, Amazonas, Brazil, infected with T. cruzi DTU TcIV. We hope our report encourages veterinarians and surveillance professionals to a take a deeper look at T. cruzi infection in domestic animals.
