The study assessed the prevalence of kissing bugs (triatomines) and their infection with Trypanosoma cruzi, the cause of Chagas disease, in nine municipalities in Rio Grande do Norte, Brazil.
Of the 842 triatomines collected, the majority were identified as Triatoma brasiliensis, with a significant percentage found in human dwellings and surrounding areas, notably in chicken coops.
The overall infection rate for T. cruzi was 30.2%, with high rates found in several species, particularly T. brasiliensis and P. lutzi, indicating their importance in the disease transmission cycle.
Objective: Trypanosoma cruzi is subdivided into six discrete typing units (DTUs), TcI-TcVI. The precise identification of each can contribute to tracking wild DTUs that invade the domiciliary environment.
