Complete mitochondrial genome of Triatoma infestans (Hemiptera, Reduviidae, Triatominae), main vector of Chagas disease.

The complete mitogenome of Triatoma infestans, the main vector of Chagas disease in South America, was obtained by combining Illumina and Sanger sequencing sequence data. The 17,301bp long genome contains 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and a control region. The number, order and orientation of mitochondrial genes are the same as in T. dimidiata, the only Triatominae mt genome published so far. The main differences between both mitogenomes are found in the control region and in the intergenic spacer between the nd1 gene and the tRNA-Ser. Comparative analysis with other Reduviidae species shows high conservation in the mt genome organization. Molecular phylogeny using all available complete mt genomes from Reduviidae species confirms the close relationship between Triatominae and Stenopodainae.
