Abstract:

High-risk human papillomavirus (HPV) infection is a requirement of cervical precancerous lesions or cervical cancer. There are many factors that affect the infection and clearance of HPV. Vaginal microflora plays an important role in the health of female lower reproductive tract. A healthy female vaginal microbiome is defined as low diversity, which is dominated by the few species of Lactobacillus. With the application of high-throughput sequencing technology for bacterial 16S rRNA gene, the structure of vaginal microbial community has been further studied. More and more research evidences show that the changes in the composition of the vaginal microflora such as the increase in the diversity of the vaginal microflora and the decrease in the relative abundance of Lactobacillus are closely related to HPV infection and the occurrence and development of cervical lesions. Reconstruction of the vaginal microbial community dominated by Lactobacillus and restoration of the vaginal microecological balance can promote the clearance of HPV. This is a new direction for the treatment of HPV infection and cervical lesions in the future. This review summarizes the correlation between the outcome of cervical HPV infection and the changes in the composition of vaginal microbial flora.
