Fig. 4.

Graphical representation of the microbiome of WT type mice highlighting the communities in the ileum and colon, for both luminal and mucosa-associated communities. Pie graphs depict the relative abundance of the major phyla (Firmicutes (pink), Bacteroidetes (yellow), Actinobacteria (blue), Verrucomicrobia (green), Fusobacteria (fusia), Proteobacteria (orange) and other (grey)). In contrast to WT mice, NHE3, NHE2, CFTR, DRA and GLUT2 knockout (KO) mice harbor an altered intestinal environment and bacterial populations. Composition is approximated from published literature.
