Abstract

Feeding sources of triatomine vectors () collected in peridomiciles in Mexico were identified by a heteroduplex assay developed with triatomine blood meals. parasites were also characterized in the same blood meal samples by multiplex-polymerase chain reaction assay of mini-exon gene inter-genic regions. The main blood meal source was from rats, but the bugs were able to feed on a wide variety of hosts, and human blood meals were identified. was the only flagellate species identified in the blood meals. All populations belong to the I lineage, a result that is consistent with the previously assumed predominance of this lineage in Mexico. This combination of blood meal and lineage identification provides a powerful tool for understanding transmission cycles.
