Although generally found in natural environment, it regularly colonizes or reinvades domiciliary ecotopes. In order to analyse gene flow between habitats, we identified and characterized six microsatellite loci using a microsatellite-enriched genomic library. To assess the usefulness of these microsatellites for genetic studies, we investigated their variability in two natural populations of the T. brasiliensis complex sampled in two Brazilian districts (Corone Jose Dia, South of Piaui state; Curaca, North of Bahia state). The taxonomic status of the samples was checked using cytb sequences. Phylogenetic analyses confirmed that the individuals from Bahia belonged to the T. juazeirensis species. primers cross-amplification was tested in 5 Triatoma species and 4 loci successfully. Moreover, amplified in T. infestans and T. guasayana. specialized Triatoma brasiliensis Chagas disease Microsatellite Cross-amplification 052 9 4 633-637 2009 1567-1348 https://www.documentation.ird.fr/hor/fdi:010046170 10.1016/j.meegid.2009.03.008 1567-1348 [F B010046170] https://www.documentation.ird.fr/hor/fdi:010046170 https://www.documentation.ird.fr/intranet/publi/2009/07/010046170.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-07-24 2017-08-23 fdi:010046170 fre
