Vaginal and rectal bacteria may have a big influence on HIV transmission and microbicide efficacy

A number of presentations at the 2016 HIV Research for Prevention Conference (HIVR4P) in Chicago looked at the influence vaginal bacteria have on HIV susceptibility, and one presentation found that vaginal bacteria may have profound effects on the levels of certain drugs used as microbicides – but not on others.

A poster at the conference also looked at the bacteria in the rectum in gay men and found a correlation between having had condomless anal sex and changes in the predominant bacterial species that may similarly increase susceptibility to HIV infection.
