SUMMARY:

In the world, there are about 6 to 8 million people infected by the protozoan Trypanosoma cruzi, the etiologic agent of Chagas disease. In Brazil, approximately 4 thousand people/year died in the last decade. The parasite stands out for its biological and genetic diversity, classified into discrete typing units (DTUs), named from TcI to TcVI, in addition to Tcbat. Transmission of T. cruzi is by triatomines, hematophagous insects that have a wide variety of food sources, with emphasis on mammals of different orders. The present work aimed to know the hosts that act as food sources for triatomines and to identify the DTUs of the protozoan in insects captured in Petrolina, a priority municipality for the control of Chagas disease in Pernambuco state. Overall, 82 triatomines were captured in the peridomicile (60) and in the intradomicile (22), which were identified as Triatoma brasiliensis (72) and T. pseudomaculata (10). Twelve insects were positive for T. cruzi infection. Currently, triatomine and T. cruzi samples are being processed to identify the food sources and DTUs of the protozoan. The results obtained will contribute with additional measures for the State Program for Surveillance and Control of Chagas Disease in Pernambuco, with emphasis on surveillance and control of reservoirs in the One Health perspective.
