Pyrosequencing of the genital microbiotas of HIV-seropositive and -seronegative women reveals Lactobacillus iners as the predominant Lactobacillus Species.

The species of vaginal lactobacilli in HIV-seropositive and -seronegative women were determined by 16S gene pyrosequencing. Lactobacillus iners sequences were the predominant lactobacillus sequences in 66% of HIV(+) women and 90% of HIV(-) women. This has implications for resistance of HIV(+) and HIV(-) women to genital colonization by pathogenic organisms.
