FIG 3.

Changes in bacterial communities according to host growth. Bacterial community composition (a) and diversity (b) were compared according to host growth using UniFrac distance-based principal-coordinate analysis, with 95% confidence ellipses. Statistical significance was evaluated using Adonis, with 999 permutations and two-tailed unpaired Student's t test. (c) OTUs that discriminate host growth were determined using random forest analysis. A higher mean decrease in accuracy indicates that an OTU makes a greater contribution to the accuracy of the random forest classification.
