Differential enrichment of the mouse colonic microbiota in response to L. reuteri supplementation on day 28 (see the Figure S1A legend for the experimental scheme). The taxonomic classifications of the bacteria are shown in the left panel. Blanks are unassigned taxa. The 36 differentially enriched bacterial taxa are ranked by estimating the mean decrease in accuracy based on random forest analysis. The right panel shows the LEfSe analysis of the 36 bacterial taxa.
