Here we display the top 50 most enriched pathways for oral singletons (A), oral non-singletons (B), gut singletons (C), and gut non-singletons (D). Blue bars are pathways enriched in both oral and gut non-singletons, red bars are pathways enriched in both oral and gut singletons, and the green bar is a pathway enriched in both oral singletons and gut non-singletons.
