Abstract excerpt

The occurrence of triatomine species and the genetic diversity of Trypanosoma cruzi were investigated in anthropogenic environments in rural areas of nine municipalities in the Campo Maior, Picos, and Alto Médio Canindé microregions, Caatinga biome, Piauí State, in northeastern Brazil. Triatomines were identified and examined for T. cruzi infection by direct microscopic examination, xenoculture, and PCR-based...
