Vaginal Microbiota Changes Caused by HPV Infection in Chinese Women.

Human papillomavirus (HPV) infection is one of the most common sexually transmitted diseases. After studying 602 unvaccinated Chinese women using 16S rRNA to detect cervical-vaginal microecology, we analyzed the relationship between HPV infection and vaginal microecology including 20 HPV types. In Chinese women, dominated and dominated clusters were significantly absence.

A cross-sectional analysis about bacterial vaginosis, high-risk human papillomavirus infection, and cervical intraepithelial neoplasia in Chinese women.

Bacterial vaginosis (BV) is a genital infection that frequently presents in women infected with human papillomavirus (HPV), but the correlation between BV, HPV and cervical intraepithelial neoplasia (CIN) development is still elusive. We organized a cross-sectional analysis which enrolled 624 participants and obtained 423 samples of vaginal secretions from them, including 193 HPV-negative samples and 230 HR-HPV-positive samples. We used 16S rRNA sequencing to measure the vaginal microbiota diversity in women with different BV, HPV and CIN status, and then calculated risk factors for CIN by logistic regression.
