Cell. Infect. Microbiol."],"abstract":"<jats:p>Cervical cancer (CC) is considered a public health problem. Recent studies have evaluated the possible relationship between the cervicovaginal microbiome and gynecologic cancer but have not studied the relationship between aerobic bacterial communities and neoplasia. The study aimed to identify the cultivable aerobic bacterial microbiota in women with cervical cancer as a preliminary approach to the metagenomic study of the cervicovaginal microbiome associated with cervical cancer in Mexican women. An observational cross-sectional study was conducted, including 120 women aged 21-71 years, divided into two study groups, women with locally advanced CC (n=60) and women without CC (n=60). Sociodemographic, gynecological-obstetric, sexual, and habit data were collected. Cervicovaginal samples were collected by swabbing, from which standard microbiological methods obtained culturable bacteria. The strains were genetically characterized by PCR-RFLP of the 16S <jats:italic>r<\/jats:italic>RNA gene and subsequently identified by sequencing the same gene. Variables regularly reported as risk factors for the disease were found in women with CC. Differences were found in the prevalence and number of species isolated in each study group. Bacteria commonly reported in women with aerobic vaginitis were identified. There were 12 species in women with CC, mainly <jats:italic>Corynebacterium<\/jats:italic> spp. and <jats:italic>Staphylococcus<\/jats:italic> spp.; we found 13 bacterial species in the group without cancer, mainly <jats:italic>Enterococcus<\/jats:italic> spp. and <jats:italic>Escherichia<\/jats:italic> spp. The advanced stages presented a more significant number of isolates and species. This study provided a preliminary test for cervicovaginal metagenomic analysis, demonstrating the presence of aerobic cervicovaginal dysbiosis in women with CC and the need for more in-depth studies.<\/jats:p>","DOI":"10.3389\/fcimb.2022.838491","type":"journal-article","created":{"date-parts":[[2022,2,2]],"date-time":"2022-02-02T05:23:37Z","timestamp":1643779417000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Preliminary Identification of the Aerobic Cervicovaginal Microbiota in Mexican Women With Cervical Cancer as the First Step Towards Metagenomic Studies"],"prefix":"10.3389","volume":"12","author":[{"given":"Gauddy Lizeth","family":"Manzanares-Leal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaime Alberto","family":"Coronel-Mart\u00ednez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Rodr\u00edguez-Morales","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iv\u00e1n","family":"Rangel-Cuevas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lilia Patricia","family":"Bustamante-Montes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Horacio","family":"Sandoval-Trujillo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ninfa","family":"Ram\u00edrez-Dur\u00e1n","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,2,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"770","DOI":"10.1007\/s10900-017-0316-9","article-title":"Cervical Cancer Screening Barriers and Risk Factor Knowledge Among Uninsured Women","volume":"42","author":"Akinlotan","year":"2017","journal-title":"J.
