AI Article Synopsis
- Studies on sandflies in the Brazilian Amazon are limited, especially regarding their role in cutaneous leishmaniasis, which is on the rise in the region.
- In Rio Branco, Acre state, researchers identified L. (Viannia) subgenus DNA in 12 out of 173 sandflies, resulting in a 6.94% positivity rate.
- The research confirmed L. (V.) braziliensis infection in five sandflies and marked new records of this infection in Evandromyia saulensis, Trichophoromyia auraensis, and Pressatia sp. in Brazil.
Article Abstract
Studies on the sandfly fauna to evaluate natural infection indexes are still limited in the Brazilian Amazon, a region with an increasing incidence of cutaneous leishmaniasis. Here, by using a multiplex polymerase chain reaction directed to Leishmania kDNA and hybridisation, we were able to identify L. (Viannia) subgenus in 12 out of 173 sandflies captured in the municipality of Rio Branco, Acre state, revealing a positivity of 6.94%. By sequencing the Leishmania 234 bp-hsp70 amplified products from positive samples, infection by L. (V.) braziliensis was confirmed in five sandflies: one Evandromyia saulensis, three Trichophoromyia auraensis and one Pressatia sp. The finding of L. (Viannia) DNA in two Ev. saulensis corresponds to the first record of possible infection associated with this sandfly. Moreover, our study reveals for the first time in Brazil, Th. auraensis and Pressatia sp. infected by L. (Viannia) parasites.
