Insect vectors were collected from 84 human dwellings in the municipality of Santo Domingo Tehuantepec, Oaxaca, Mexico; 4.76% were infested. DTUs were determined using conventional and nested PCR.Results:
The infection rate was 43.6%. All insects were infected with TcI while one specimen showed mixed infection with TcII.Conclusions:
This is the first report of T. cruzi mixed infection in Triatoma phyllosoma, its main vector in the study region.
