Gut microbial diversity and biomarkers. Each fecal sample was regarded as an experimental unit (n = 6 per group). A Abundance of gut bacteria at phylum level in different samples. B F/B Ratio of different groups. C α-diversity index (Shannon, chao1, PD whole tree, observed species). D PCoA of gut microbiota. E Linear discriminant analysis (LDA) effect size (LEfSe). F Relative abundance of core genera in different experimental groups. All data represent the mean ± SEM. Statistical differences in mean values were evaluated by independent t-test and by Mann Whitney test. 0.05 < P < 0.10 indicated a statistical trend of change; *P < 0.05 and **P < 0.01
