Blood meal source and mixed blood-feeding influence gut bacterial community composition in Aedes aegypti.

ABSTRACT:

Background

The guts of blood-sucking insects host a community of bacteria that can shift dramatically in response to biotic and abiotic factors. Identifying the key factors structuring these microbial communities has important ecological and epidemiological implications.

Methods

We used the yellow fever mosquito, Aedes aegypti, to investigate the impact of mixed blood meals on gut microbiota of vector mosquitoes. Adult females were experimentally fed on sugar or blood from chicken, rabbit or a mixture of chicken and rabbit blood, and their gut microbiota were characterized using 16S rRNA gene amplification and MiSeq sequencing.

Results

The gut bacterial communities of mosquitoes fed on the three blood meal treatments clustered separately, suggesting that host species
