Diversity Analysis of Vaginal Microbiota on Women With High-risk Human Papillomavirus Infection

Since other genital infections enhance HIV susceptibility by inducing inflammation, the investigators study the relationship between the vaginal microbiota composition and the risk of HPV infection, cervical cytological abnormalities.

Persistent infection with oncogenic Human Papillomavirus (HPV) is necessary but not sufficient for the development of cervical cancer. Additional factors correlated with HPV persistence include immunodeficiency caused by HIV, smoking, use of oral contraceptives and, more recently reported, vaginal dysbiosis. In a state of dysbiosis, there is a marked reduction of Lactobacillus and a high diversity of bacteria, with increased abundance of anaerobic bacterial species. Based on this, the investigators are going to analyze the changes of microbiota in women with high-risk HPV and the cervical lesions. And the investigators hope to figure out the difference and change in microbiota to realize the tanning of cervical lesions.
