The diversity of vaginal species in CC patients is higher than that in high-risk HPV infection or CIN patients. The main manifestation is an increase in the diversity of vaginal microbes, a decrease in the relative abundance of cyanobacteria and Lactobacillus, and an increase in the relative abundance of dialister, peptonephila and other miscellaneous bacteria. There are characteristic vaginal biomarker in normal women, high risk HPV patients and CC patients. In detail, the biomarker in the normal group was varibaculum, the biomarker in the high-risk HPV group was saccharopolyspora, the biomarker of the CC group was the Proteobacteria, Corynebacterium, Coprococcus, Peptococcus and Ruminococcus.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The study indicated that the compositions of vaginal microbes in different cervical lesions is different. The vaginal microbial composition has a certain diagnostic effect on healthy women, patients with high-risk HPV infection and cervical lesions. These microbes may serve as potential biomarkers for CC. It also provided an effective way for the treatment of HPV infections and cervical lesions.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcimb.2024.1405789","type":"journal-article","created":{"date-parts":[[2024,8,16]],"date-time":"2024-08-16T05:10:21Z","timestamp":1723785021000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":17,"title":["Analysis of the correlation between cervical HPV infection, cervical lesions and vaginal microecology"],"prefix":"10.3389","volume":"14","author":[{"given":"Zhongru","family":"Fan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongyu","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Fan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,8,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0150767","article-title":"Unique Insights in the Cervicovaginal Lactobacillus iners and L. crispatus Proteomes and Their Associations with Microbiota Dysbiosis","volume":"11","author":"Borgdorff","year":"2016","journal-title":"PloS One"},{"key":"B2","doi-asserted-by":"publisher","first-page":"30","DOI":"10.1186\/2049-2618-1-30","article-title":"Genome resolved analysis of a premature infant gut microbial community reveals a Varibaculum cambriense genome and a shift towards fermentation-based metabolism during the third week of life","volume":"1","author":"Brown","year":"2013","journal-title":"Microbiome."},{"key":"B3","doi-asserted-by":"publisher","first-page":"9","DOI":"10.1016\/j.ajog.2018.12.011","article-title":"Vaginal dysbiosis and the risk of human papillomavirus and cervical cancer: systematic review and meta-analysis","volume":"221","author":"Brusselaers","year":"2019","journal-title":"Am.
