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.
