a A Venn diagram showing shared and unique OTUs among the three groups. The Chao1 index (b) and the Shannon index (c) for alpha diversity estimation. d Principal-coordinate analysis (PCoA) plot showing the similarity relations among the three groups. n = 6 per group. *p < 0.05, **p < 0.01, vs. chow group; #p < 0.05, ##p < 0.01, vs. HFD group
