Bray-Curtis dissimilarity and microbiota composition among four groups in vaginal and meconium microbiota. (A) In vaginal microbiota, Bray-Curtis dissimilarity (top) and the distinct genus (bottom, P < 0.05) between groups after pairwise comparison. (B) In meconium microbiota, the Bray-Curtis dissimilarity (top) and the distinct genus (bottom, P < 0.05) between groups after pairwise comparison. (C) Bray-Curtis dissimilarity of microbiota between vagina and meconium in four groups. (D) Neonatal meconium (N) and maternal vaginal (M) microbiota composition of EOS infants and their mothers (*, P < 0.050; **, P < 0.010; and ***, P < 0.001).
