| Abstract | Innovative approaches used to combat Chagas disease transmission tend to combine a set
of comprehensive efforts to understand the ecology of local vectors. In this work we identified
molecularly the blood meal of 181 Triatoma brasiliensis, distributed in 18 populations (8
sylvatic and 10 peridomestic), which were collected across a range of 240 km (East-West)
and 95 km (North-South) in the semi-arid region of northeastern, Brazil. We used the vertebrate
mitochondrial gene (cytochrome B) sequencing applied to DNA isolated from bug midgut
to identify the insect blood meal sources via the BLAST procedure. The peridomestic
populations were classified according to two main hypotheses of site-occupancy for T. brasiliensis:
the first says that the infestation is mainly driven by structures that resemble its natural
habitat (stony-like ecotopes) and the second assumes that it is associated with key-hosts
(rodents and goats). Rodents of the Caviidae family (Galea spixii and Kerodon rupestris)
were identified as the key-host of T. brasiliensis, but also the potential Trypanosoma cruzi
reservoir–able to connect the sylvatic and domestic T. cruzi cycle. Cats also deserve to be
studied better, as potential T. cruzi reservoirs. By modeling the food sources + site-occupancy
+ T. cruzi natural infection, we identified man-made ecotopes suitable for forming
dense triatomine infestations with high rates of T. cruzi natural infection, which may be
taken into account for vector control measures. | pt_BR |
