“Ca. M. girerdii” is associated with African American race and elevated vaginal pH.

Mean proportions of the most common racial groups and median values for mid-vaginal pH were calculated for carriers and non-carriers (i.e., 0.1% 16S rRNA microbiome threshold) of the genital mycoplasmas and representative BV-associated species of women recruited from 1,361 women recruited from outpatient clinics. Bootstrap analysis was performed so that values represent the underlying population of the clinic.*Bootstrap probabilities (n = 1,000) less than 0.05 indicate that the mean proportion or median value is significantly higher for carriers of the species.“Ca. M. girerdii” is associated with African American race and elevated vaginal pH.

本研究针对从门诊诊所招募的1361名女性，为生殖支原体（genital mycoplasmas）及细菌性阴道病（Bacterial Vaginosis, BV）相关代表性菌种的携带者与非携带者（以0.1%的16S rRNA微生物组（16S rRNA microbiome）丰度作为判定阈值），计算了其最常见种族群体的平均占比，以及阴道中段pH值的中位数。本研究采用自举分析（Bootstrap analysis）进行统计检验，所得结果可反映该门诊的目标人群总体特征。*自举概率（重复抽样次数n=1000）小于0.05时，表明对应菌种携带者的平均占比或中位数水平显著更高。"Ca. M. girerdii"与非裔美国人种族及阴道pH值升高显著相关。
