Methods Totally 237 reproductive-aged women with RVVC in an acute episode were studied. Whereas 230 healthy reproductive-aged women were enrolled as the control. The vaginal pH was evaluated, while vaginal secretions were sampled for Gram's staining and oilmicroscopy. By Nugent score system, the composition of vaginal communities was determined, and other micro-ecological features were approached. To describe other features of vaginal microbiota, the community's bacteria density, species diversity and predominant species were evaluated at 1 000 X magnification. Results The vaginal pH (4.53 ~ 0.30) and Nugent score (4.31 ___+ O. 73) in RVVC group were significantly increased compared with vaginal pH (4.11 __+ 0.30) and Nugent score (1.32 _+ 1.29) in control group (P〈O.05, respectively). The density of Lactoba- cillus in RVVC group was significantly lower than that in control group (P〈O.05), while the densities of Gardnerella vaginalis, Gram-positive cocci and other species were significantly higher respectively than those in control group (P〈O. 05). Species diversity of women with RVVC significantly exceeded that of control group (P〈O.05). More than half of vaginal communities in R VVC group lost Lactobacillus-dominating and were predominated by other bacteria such as Gardnerella vaginalis and Gram-positive cocci. The prevalence of Gardnerella vaginalis-dominating and Gram-positive cocci-domi- nating communities in RVVC group (37.55% and 19.83%) were significantly higher than those in control group (1.30% and 1.73%) (P〈0.05). Conclusion The significant changes in vaginal bacterial community were observed in RVVC women. Such variations in community might relate to vaginal biological barrier compromising and increase the risk to the recurrence of VVC. It is still controversial whethe展开更多
