BACKGROUND The northern limits of Trypanosoma cruzi across the territory of the United
States remain unknown. The known vectors Triatoma sanguisuga and T. lecticularia find …

the parasite during the chronic phase of Chagas disease (ChD), parasitological and …

Trypanosoma cruzi, the etiological agent of Chagas disease, was initially classified into 6
Discrete Typing Units (DTUs). The hybrid DTUs TcV and TcVI are the most frequent in …

American trypanosomiasis or Chagas disease is endemic in Latin America and caused by
the flagellate Trypanosoma cruzi, which exhibits broad genetic variation. In various areas …
