Abstract

Background The bacterial community present in the abdomen in Anophelinae mosquitoes can influence mosquito susceptibility toPlasmodiuminfection. Little is known about the bacteria associated withNyssorhynchus darlingi, a primary malaria vector in the Amazon basin. We investigated the abdominal bacterial community compositions of naturallyPlasmodium-infected (P-positive,n = 9) and non-infected (P-negative,n = 7)Ny. darlingifrom the Brazilian Amazon region through massive parallel sequencing of the bacterial V4 variable region of the 16S rRNA gene. Results Bacterial richness ofNy. darlingiencompassed 379 operational taxonomic units (OTUs), the majority of them belonging to theProteobacteria,FirmicutesandBacteroidesphyla.Escherichia/ShigellaandP seudomonaswere more abundant in theP-positive andP-negative groups, respectively, than in the opposite groups.Enterobacterwas found only in theP-negative group. The results of statistical analyses conducted to compare bacterial abundance and diversity betweenPlasmodium-infected andPlasmodium-non-infected mosquitoes were not significant. Conclusions This study increased knowledge about bacterial composition inNy. darlingiand revealed thatPlasmodium-positive andPlasmodium-negative groups share a common core of bacteria. The generaPrevotella9,Sphingomonas,Bacteroides, andBacilluswere reported for the first time inNy. darlingi. (AU)
