We used the gut contents of triatomines collected from rural areas of Ceará State, northeastern Brazil, to identify their putative hosts via vertebrate gene sequencing. Successful direct sequencing was obtained for 48% of insects, comprising 50 , 7 , and 1 . Basic local alignment search tool (BLAST) procedure revealed that domestic animals, such as chickens () and goats (), are the main food source, including in sylvatic environment. Native hosts were also detected in peridomestic environment such as reptiles ( sp. and ) and the (Rodentia: Caviidae). The role of goats and in Chagas disease epidemiology calls for further studies, because these mammals likely link the sylvatic and domestic cycles.
