Background: The Trypanosoma cruzi parasite is the causal agent of Chagas disease, recognized by the World Health Organization as a neglected tropical disease. Currently there are seven discrete typing units (DTUs) of T. cruzi distributed in America, but there are still gaps about its distribution in some endemic regions. Materials and Methods: Seventeen units isolated from Chiapas and Oaxaca in Mexico were identified by amplification of the C-5 sterol desaturase gene. Results: Three DTUs of T. cruzi, TcI (6), TcII (10), and TcIV (1) were detected by comparing polymorphic sites in specific regions. Conclusions: New DTUs are reported for both states, where TcII was the most common DTU. The genetic characterization of the isolates can help to understand the epidemiology of Chagas disease.
