First Report of (Hemiptera: Reduviidae) Infected with in Peridomestic Environment in Chiapas, Mexico.

Triatomine bugs are natural vectors of , which causes Chagas disease or American trypanosomiasis. The role of sylvatic triatomine species as vectors of . in Mexico remains to be fully understood. Our research on the epidemiology of Chagas disease in Southeastern Mexico involved sampling triatomines in rural settings. A triatomine was collected in a peridomestic environment of a rural dwelling in the state of Chiapas. The triatomine was identified morphologically as an adult female Stal. Microscopic analysis revealed flagellate forms of in the feces of the . collected. This was confirmed by quantitative polymerase chain reaction. Amplification of the mini-exon gene showed that the infecting . corresponded to lineage I. This is the first report from Mexico of . found infected in a human dwelling, which represents an important adaptation process to inhabit human environments.
