(A) The proportion of dominant Genus communities in each group of samples. Genus communities less than 5% was merged into others. (B) Distribution of three dominant Family (Lachnospiraceae, Enterobacteriaceae and Porphyromonadaceae) in each groups. (C) Distribution of three dominant Genus (Escherichia-Shigella, Citrobacter and Enterococcus) in each groups. Data were exhibited as the mean ± SD (n=4 mice per group). *P<0.05, **P<0.01 vs. DSS group; ^#P<0.05, ^##P<0.01, ^###P<0.001 vs. Vehicle group.
