Trypanosoma cruzi discrete typing unit TcIV implicated in a case of acute Chagas disease in a domiciliated dog in the western Amazon

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 role of epidemiological sentinels being domestic reservoirs T. The aim current study was to report first case CD in a dog Manaus, Amazonas, Brazil, infected with cruzi DTU TcIV.
