However, its composition and interactions with bacterial communities remain poorly understood, particularly among Hispanic women, who experience disproportionately high rates of Human papillomavirus (HPV) infection and cervical cancer. We characterized the vaginal mycobiota across reproductive stages and examined its associations with cervical disease, HPV status, and bacterial community state types (CSTs) in 86 Hispanic participants from Puerto Rico using ITS1 amplicon sequencing. Amplicon sequence variants were inferred with QIIME2\/DADA2 and taxonomically classified using the UNITE database, with diversity and discriminant taxa analyses applied to explore clinical and microbial associations. We detected 173 fungal Species Hypotheses, dominated by\n                  <jats:italic>Candida albicans<\/jats:italic>\n                  ,\n                  <jats:italic>Agaricomycetes<\/jats:italic>\n                  sp.,\n                  <jats:italic>Scopuloides dimorpha<\/jats:italic>\n                  , and\n                  <jats:italic>Hortaea werneckii<\/jats:italic>\n                  . While fungal composition did not differ significantly by reproductive stage, non-pregnant individuals exhibited greater inter-individual variability. Alpha diversity was reduced in high-grade squamous intraepithelial lesions compared with low-grade or normal cytology, and\n                  <jats:italic>Candida parapsilosis<\/jats:italic>\n                  prevalence was elevated in low-grade lesions. CST III, characterized by\n                  <jats:italic>Lactobacillus iners<\/jats:italic>\n                  dominance, showed greater dispersion variance than other CSTs. Collectively, these findings reveal a diverse vaginal mycobiome with stage- and disease-specific features, and a notable contribution of environmental fungi that may influence cervical pathogenesis. This work provides foundational insight into cervicovaginal fungal ecology in a high-risk Hispanic population and highlights the importance of integrating bacteriome\u2013mycobiome analyses in women\u2019s health research.\n                <\/jats:p>","DOI":"10.64898\/2026.01.21.700834","type":"posted-content","created":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T14:40:23Z","timestamp":1769092823000},"source":"Crossref","is-referenced-by-count":1,"title":["Environmental Fungi Modulate the Vaginal Mycobiome and Cervical Disease Progression in Hispanic Women"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1880-0498","authenticated-orcid":false,"given":"Filipa","family":"Godoy-Vitorino","sequence":"first","affiliation":[{"name":"Department of Microbiology, University of Puerto Rico, School of Medicine, Medical Sciences Campus, San Juan, PR 00936, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Vargas-Robles","sequence":"additional","affiliation":[{"name":"Department of Microbiology, University of Puerto Rico, School of Medicine, Medical Sciences Campus, San Juan, PR 00936, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin","family":"Bola\u00f1os-Rosero","sequence":"additional","affiliation":[{"name":"Department of Microbiology, University of Puerto Rico, School of Medicine, Medical Sciences Campus, San Juan, PR 00936, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Pag\u00e1n-Zayas","sequence":"additional","affiliation":[{"name":"Department of Microbiology, University of Puerto Rico, School of Medicine, Medical Sciences Campus, San Juan, PR 00936, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Cort\u00e9s-Nazario","sequence":"additional","affiliation":[{"name":"Department of Microbiology, University of Puerto Rico, School of Medicine, Medical Sciences Campus, San Juan, PR 00936, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kara","family":"Wiggin","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Scripps Institution of Oceanography, University of California San Diego, La Jolla, CA 92093, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah","family":"Allard","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Scripps Institution of Oceanography, University of California San Diego, La Jolla, CA 92093, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josefina","family":"Romaguera","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of Puerto Rico, School of Medicine, Medical Sciences Campus, San Juan, PR 00936, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7920-7001","authenticated-orcid":false,"given":"Jack A.","family":"Gilbert","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Scripps Institution of Oceanography, University of California San Diego, La Jolla, CA 92093, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2026020608391216000_2026.01.21.700834v1.1","doi-asserted-by":"publisher","DOI":"10.1186\/2049-2618-1-1"},{"key":"2026020608391216000_2026.01.21.700834v1.2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1002611107"},{"key":"2026020608391216000_2026.01.21.700834v1.3","unstructured":"Godoy-Vitorino, F. , et al., Malassezia globosa and Malassezia restricta are associated with high-risk HPV infections in the anogenital tract.
