Fig. 1.

Intestinal microbiota community structure of 2 groups (vaginal delivery and cesarean section) in 3 days neonates.(A) Intestinal microbiota community heatmap analysis on the genus level of the two groups.(B) Wilcoxon rank-sum test bar plot on the genus level between the two groups.(C) Principal coordinate analysis (PCoA) on unweighted UniFrac distances between the neonatal microbiota is shown along the first two principal coordinates (PC) axes. Each point represents a single sample and is colored by a delivery mode: vaginal delivery, blue; cesarean section, red. The closer the two sample points are, the more similar the species composition is.(D) PCoA box diagram. Represents the discrete distribution of different groups of samples on the PC1 axis: vaginal delivery, blue; cesarean section, red.
