Distribution of Genital Lactobacillus Strains Shared by Female Sex Partners
Open accessAbstract
The prevalence of bacterial vaginosis among lesbians is high. We assessed whether unique Lactobacillus strains were shared by female sex partners. Cultures of vaginal and rectal specimens for detection of Lactobacillus organisms were performed for women who reported having had sex with women. Lactobacilli were identified on the basis of DNA homology and were typed and fingerprinted by repetitive element sequence-based polymerase chain reaction (rep-PCR). Of 237 women, Lactobacillus crispatus was detected in 98% and Lactobacillus gasseri in 21%. Detection of L. gasseri was associated with recent receptive digital-vaginal sex (P = .04) and increased bacterial vaginosis risk (odds ratio, 4.2; 95% confidence interval, 1.4-13.4). Of 31 couples monogamous for >3 months, rep-PCR fingerprints were identical in both members in 23 (77%).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
