Vaginal microbiota community in cases with severe preeclampsia (n = 30) and control women (n = 30). (a) Richness and diversity indices of the vaginal microbiota were calculated from 16S ribosomal RNA gene sequencing of the V3–V4 region on a MiSeq platform. (b) A principal component analysis plot was constructed using unweighted UniFrac analysis.
