BACKGROUND Bacterial vaginosis affects millions of women and is associated with several serious health conditions. The cause of bacterial vaginosis remains poorly understood despite numerous studies based on cultures. Bacteria in microbial communities can be identified without cultivation by characterizing their ribosomal DNA (rDNA) sequences. METHODS We(More)
Several novel bacterial species have been detected in subjects with bacterial vaginosis (BV) by using broad-range PCR assays, but this approach is insensitive for detecting minority species. We developed a series of taxon-directed 16S rRNA gene PCR assays for more sensitive detection of key vaginal bacteria. We sought to determine the prevalence of each(More)
BACKGROUND Bacterial vaginosis (BV) is a common condition that is associated with numerous adverse health outcomes and is characterized by poorly understood changes in the vaginal microbiota. We sought to describe the composition and diversity of the vaginal bacterial biota in women with BV using deep sequencing of the 16S rRNA gene coupled with(More)
Bacterial vaginosis (BV) may be common among women who report having sex with women (WSW) and frequently occurs in both members of monogamous couples. The results of Gram staining of a vaginal smear were consistent with BV in 81 (25%) and intermediate in 37 (11%) of 326 WSW included in this study. Lactobacilli were detected in 64% of subjects, and 42% of(More)
Several fastidious bacteria have been associated with bacterial vaginosis (BV) using broad-range bacterial PCR methods such as consensus sequence 16S rRNA gene PCR, but their role in BV remains poorly defined. We describe changes in vaginal bacterial concentrations following metronidazole therapy for BV. Vaginal swabs were collected from women with BV(More)
BACKGROUND Little is known about short-term bacterial fluctuations in the human vagina. This study used PCR to assess the variability in concentrations of key vaginal bacteria in healthy women and the immediate response to antibiotic treatment in women with bacterial vaginosis (BV). METHODOLOGY/PRINCIPAL FINDINGS Twenty-two women assessed for BV using(More)
Bacterial vaginosis (BV) is a common syndrome associated with numerous adverse health outcomes in women. Despite its medical importance, the etiology and microbial ecology of BV remain poorly understood. We used broad-range PCR to census the community structure of the healthy and BV-affected vaginal microbial ecosystems and synthesized current publicly(More)
OBJECTIVES The purpose of this study was to examine frequency of and attitudes toward Papanicolaou (Pap) test screening in women who have sex with women (WSW) and to determine prevalence of genital human papillomavirus (HPV). METHODS Women were eligible if they reported having engaged in sex with another woman in the preceding year Medical and sexual(More)
Few evaluations of tests for Chlamydia trachomatis have compared nucleic acid amplification tests (NAATs) with diagnostic tests other than those by culture. In a five-city study of 3,551 women, we compared the results of commercial ligase chain reaction (LCR) and PCR tests performed on cervical swabs and urine with the results of PACE 2 tests performed on(More)
BACKGROUND Bacterial vaginosis (BV) is common in women who have sex with women. While cross-sectional data support a role for sexual transmission, risks for incident BV have not been prospectively studied in this group. METHODOLOGY/PRINCIPAL FINDINGS We studied risks for BV acquisition in a prospective cohort study of women (age 16-35 years) who reported(More)
