Relationship of Specific Bacteria in the Cervical and Vaginal Microbiotas With Cervicitis.

BACKGROUND: Cervicitis is an inflammatory condition of the cervix associated with upper genital tract infection and reproductive complications. Although cervicitis can be caused by several known pathogens, the etiology frequently remains obscure. Here we investigate vaginal bacteria associated with bacterial vaginosis as potential causes of cervicitis. METHODS: Associations between vaginal bacteria and cervicitis were assessed in a retrospective case-control study of women attending a Seattle sexually transmitted disease clinic. Individual bacterial species were detected using 2 molecular methods: quantitative polymerase chain reaction (qPCR) and broad-range 16S rRNA gene PCR with pyrosequencing. The primary finding from this initial study was evaluated using qPCR in a second cohort of Kenyan women. RESULTS: The presence of Mageeibacillus indolicus, formerly BVAB3, in the cervix was associated with cervicitis, whereas the presence of Lactobacillus jensenii was inversely associated. Quantities of these bacteria did not differ between cervicitis cases and controls, although in a model inclusive of presence and abundance, M. indolicus remained significantly associated with cervicitis after adjustment for other cervicitis-causing pathogens. M. indolicus was not associated with cervicitis in our study of Kenyan women, possibly due to differences in the clinical definition of cervicitis. CONCLUSIONS: Colonization of the endocervix with M. indolicus may contribute to the clinical manifestations of cervicitis, but further study is needed to determine whether this finding is repeatable and applicable to diverse groups of women. Colonization of the cervix with L. jensenii could be a marker of health, perhaps reducing inflammation or inhibiting pathogenic infection.

Sexually transmitted infections among women who have sex with women.

Women who have sex with women (WSW) are a diverse group with variations in sexual identity, sexual behaviors, sexual practices, and risk behaviors. WSW are at risk of acquiring bacterial, viral, and protozoal sexually transmitted infections (STIs) from current and prior partners, both male and female. Bacterial vaginosis is common among women in general and even more so among women with female partners. WSW should not be presumed to be at low or no risk for STIs based on sexual orientation, and reporting of same-sex behavior by women should not deter providers from considering and performing screening for STIs, including chlamydia, in their clients according to current guidelines. Effective delivery of sexual health services to WSW requires a comprehensive and open discussion of sexual and behavioral risks, beyond sexual identity, between care providers and their female clients.

Emerging Sexual Health Issues Among Women Who Have Sex with Women.

Women who have sex with women (WSW) comprise a diverse group of people who evidence a spectrum of sexual identity, sexual behaviors, sexual practices, and risk behaviors. WSW are at risk of acquiring a diversity of sexually transmitted infections (STIs) from current and prior partners, both male and female. Notably, human papillomavirus (HPV) is sexually transmitted between female partners, and Pap smear guidelines should be followed in this group. Bacterial vaginosis is common among WSW. WSW should not be presumed to be at low or no risk for STIs based on sexual orientation, and reporting of same sex behavior by women should not deter providers from considering and performing screening for STIs, including Chlamydia trachomatis, according to current guidelines. Effective delivery of sexual health services to WSW requires a comprehensive and open discussion of sexual and behavioral risks, beyond sexual identity, between care providers and their female clients.
