[HTML][HTML] Trypanosoma cruzi genotypes in Mepraia gajardoi from wild ecotopes in northern Chile
The American Journal of Tropical Medicine and Hygiene, 2013•ncbi.nlm.nih.gov
We evaluated Trypanosoma cruzi infection in 397 wild Mepraia gajardoi specimens from five
coastal localities in northern Chile by detection of minicircle DNA by polymerase chain
reaction. The wild capture sites were classified into two ecotopes: a fully wild ecotope
(ecotope 1) and a wild ecotope near human dwellings (ecotope 2). Infection rates varied
between 11% and 27%. Minicircle hybridization assays showed that T. cruzi lineages Tc II
and Tc VI were commonly detected in ecotope 1 and ecotope 2, respectively. These results …

Abstract
We evaluated Trypanosoma cruzi infection in 397 wild Mepraia gajardoi specimens from five coastal localities in northern Chile by detection of minicircle DNA by polymerase chain reaction. The wild capture sites were classified into two ecotopes: a fully wild ecotope (ecotope 1) and a wild ecotope near human dwellings (ecotope 2). Infection rates varied between 11% and 27%. Minicircle hybridization assays showed that T. cruzi lineages Tc II and Tc VI were commonly detected in ecotope 1 and ecotope 2, respectively. These results are discussed in the context of insect proximity to human dwellings, the alimentary profile of Mepraia sp., T. cruzi lineages detected in the past in the same disease-endemic area circulating in humans, and Triatoma infestans.
