Bacterial communities of mother’s feces by H. pylori status. (A) Rarefaction plots of bacterial communities using PD whole tree matrix (Left) and number of observed species (Right). The non-parametric P values were calculated using 10,000 Monte Carlo permutation. (B) PCoA plot of bacterial communities using unweighted (Left) and weighted (Right) UniFrac distances. PERMANOVA was used to test dissimilarity. (C) Bacterial taxa plots. Each taxonomy (>1% of average relative abundance in any groups) is indicated by a different color at the genus level. LDA Effect Size (>3.0-fold) was used to detect overrepresented taxa.
