Bacterial taxa and predictive functional profiling comparisons in intestinal microbiota from infants by maternal H. pylori status according to mode of delivery. (A) Bacterial taxa plots. Each taxonomy (>1% of average relative abundance in any groups) is indicated by a different color at the genus level. (**) indicates overrepresented major taxa. (B) Histogram of overrepresented taxa in each group (LEfSe analysis between two groups, LDA > 3.0; approx. p < 0.001). (C) Histogram of overrepresented functional profiles in each group. Overrepresented functional routes in predicted metagenomes were detected using LDA Effect Size test (LEfSe analysis between two groups, LDA > 3.0; approx. p < 0.001).
