Evaluar la diversidad morfol\u00f3gica y din\u00e1mica de la microbiota vaginal en adolescentes y j\u00f3venes embarazadas. Material y m\u00e9todos. Se analizaron muestras de exudado vaginal tomadas en cada visita prenatal. Se utiliz\u00f3 tinci\u00f3n de Gram para la caracterizaci\u00f3n morfol\u00f3gica y los criterios de Nugent para diagnosticar vaginosis bacteriana (VB). Resultados. De 501 embarazadas, 31.1% present\u00f3 VB. Ser soltera, alto consumo de alcohol y tener tres o m\u00e1s parejas sexuales fueron factores de riesgo; el uso previo de antibi\u00f3ticos y antecedentes de infecci\u00f3n urinaria fueron protectores. En 173 participantes con seguimiento, se observ\u00f3 una disminuci\u00f3n de los morfotipos Mobiluncus y Gardnerella y un aumento de Lactobacillus. La VB disminuy\u00f3 de 37.0 a 7.7% entre la primera y tercera visita. El 50.0% de las embarazadas con VB y 64.7% con microbiota intermedia restablecieron a microbiota normal en la siguiente visita, mientras que 5% con microbiota normal desarroll\u00f3 VB. La incidencia de VB fue de 8.03 casos\/100 mujeres\/trimestre y la persistencia de 32.8%. Conclusiones. La prevalencia e incidencia de VB fue alta entre las adolescentes y j\u00f3venes embarazadas. La microbiota vaginal durante el embarazo es variable. Aunque tiende a normalizarse, una proporci\u00f3n evoluciona a VB, representando un riesgo significativo de complicaciones.<\/jats:p>","DOI":"10.21149\/16730","type":"journal-article","created":{"date-parts":[[2025,10,23]],"date-time":"2025-10-23T01:06:23Z","timestamp":1761181583000},"page":"466-476","source":"Crossref","is-referenced-by-count":0,"title":["Evaluaci\u00f3n de la diversidad morfol\u00f3gica y din\u00e1mica de la microbiota vaginal en adolescentes y j\u00f3venes embarazadas"],"prefix":"10.21149","volume":"67","author":[{"given":"Maria","family":"Olamendi-Portugal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roc\u00edo Guadalupe","family":"Arias-Morales","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julio C\u00e9sar","family":"Mu\u00f1iz-Salgado","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Santa","family":"Garc\u00eda-Cisneros","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel Angel","family":"S\u00e1nchez-Alem\u00e1n","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonia","family":"Herrera Ortiz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8786","published-online":{"date-parts":[[2025,9,26]]},"container-title":["Salud P\u00fablica de M\u00e9xico"],"original-title":[],"link":[{"URL":"https:\/\/saludpublica.mx\/index.php\/spm\/article\/download\/16730\/12723","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/saludpublica.mx\/index.php\/spm\/article\/download\/16730\/12723","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,23]],"date-time":"2025-10-23T01:06:29Z","timestamp":1761181589000},"score":1,"resource":{"primary":{"URL":"https:\/\/saludpublica.mx\/index.php\/spm\/article\/view\/16730"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,9,26]]},"references-count":0,"journal-issue":{"issue":"5 (sept-oct)","published-online":{"date-parts":[[2025,9,26]]}},"URL":"https:\/\/doi.org\/10.21149\/16730","relation":{},"ISSN":["1606-7916","0036-3634"],"issn-type":[{"value":"1606-7916","type":"electronic"},{"value":"0036-3634","type":"print"}],"subject":[],"published":{"date-parts":[[2025,9,26]]}}}
