The objective of this study was to assess in prospective data whether bacterial vaginosis (BV) is associated with gonococcal/chlamydial cervicitis.
A total of 1179 women at high risk for sexually transmitted infections was followed for a median of 3 years. Every 6 to 12 months, vaginal swabs were obtained for Gram stain, culture of microflora, and Neisseria gonorrhoeae and Chlamydia trachomatis. A Gram stain score of 7 to 10 based on the Nugent criteria categorized BV.
Baseline BV was associated with concurrent gonococcal/chlamydial infection (adjusted odds ratio, 2.83; 95% confidence interval [CI], 1.81-4.42). However, the association between BV and subsequent, incident gonococcal/chlamydial genital infection was not significant (adjusted relative risk [RR], 1.52; 95% CI, 0.74-3.13). Dense growth of pigmented, anaerobic Gram-negative rods (adjusted RR, 1.93; 95% CI, 0.97-3.83) appeared to elevate the risk for newly acquired gonococcal/chlamydial genital infection.
BV was common among a predominantly black group of women with concurrent gonococcal/chlamydial infection but did not elevate the risk for incident infection.

- "Some of these organisms are also commonly observed in the vaginal microbial communities of asymptomatic women , as well as women with bacterial vaginosis ,  and upper genital tract pathology , . Similar anaerobic communities in female genital tract are associated with increased risk for STI . These observations suggest the hypothesis that establishment of BV-like communities in the male urethra is similarly associated with STI risk. "

ABSTRACT: The microbiome of the male urogenital tract is poorly described but it has been suggested that bacterial colonization of the male urethra might impact risk of sexually transmitted infection (STI). Previous cultivation-dependent studies showed that a variety of non-pathogenic bacteria colonize the urethra but did not thoroughly characterize these microbiomes or establish links between the compositions of urethral microbiomes and STI.
Here, we used 16S rRNA PCR and sequencing to identify bacteria in urine specimens collected from men who lacked symptoms of urethral inflammation but who differed in status for STI. All of the urine samples contained multiple bacterial genera and many contained taxa that colonize the human vagina. Uncultivated bacteria associated with female genital tract pathology were abundant in specimens from men who had STI.
Urine microbiomes from men with STI were dominated by fastidious, anaerobic and uncultivated bacteria. The same taxa were rare in STI negative individuals. Our findings suggest that the composition of male urine microbiomes is related to STI.

- "Bacterial vaginosis (BV) is a common condition causing various symptoms such as vaginal
discharge, odor and irritation, and has been associated with increased
acquisition of many sexually transmitted diseases [1, 2]. Pregnant women with BV have an increased risk
of preterm labor and preterm delivery with the potential for neonatal morbidity
and mortality . "

ABSTRACT: The presence of semen in vaginal fluid, as identified by an acid phosphatase spot test, does not influence vaginal proinflammatory cytokine concentrations.
Determine whether semen, as detected by acid phosphatase, influences vaginal cytokines or secretory leukocyte protease inhibitor concentrations. METHODs: 138 pregnant women had vaginal fluid collected for Gram stain, acid phosphatase detection by colorimetric assay, and interleukin 1-Beta, interleukin-6, interleukin-8, and secretory leukocyte protease inhibitor measurement by enzyme immunoassay. Results for women with and without acid phosphatase were compared by Mann-Whitney test.
Of 138 subjects, 28 (20%) had acid phosphatase detected; of these, only 19 (68%) reported recent intercourse and 3 (11%) had sperm seen on Gram stain. There were no significant differences in proinflammatory cytokine concentrations; however, secretory leukocyte protease inhibitor concentrations were significantly higher among women with acid phosphatase.
Proinflammatory cytokine measurement does not appear to be affected by the presence of semen, but secretory leukocyte protease inhibitor is significantly higher when semen is present. Detection of semen by acid phosphatase was associated with higher vaginal SLPI concentrations, however, the presence of semen did not appear to influence vaginal proinflammatory cytokine concentrations.
