Abstract
Introduction
The cervicovaginal microbiome is a proposed modifier of HPV-associated cervical disease, yet its relationship with viral type heterogeneity, cytological grade, and community state type (CST) remains incompletely understood.
Methods
This cross-sectional study characterized cervicovaginal microbiome composition and functional potential across HPV infection status, viral type categories (No HPV, HPV High Risk, HPV16, HPV18, HPV Other), cervical cytological grades, and CSTs in 311 non-pregnant women using whole-genome shotgun metagenomic sequencing, integrated diversity analyses, MaAsLin2 differential abundance testing, and HUMAnN 3.0 functional pathway profiling.
