Fig. 4
Analysis of Community Composition of the gut microbiota in mice. (A) UniFrac principal co-ordinate analysis (PCoA) (n = 4). Each point in the figure represents a sample, and points of the same color belong to the same group. The distance between points reflects the similarity between samples. (B) Anosim test result for β-diversity is used to examine whether the differences between groups are significantly greater than the differences within groups, thereby determining the significance of the grouping. (C) Boxplot of α-diversity analysis (Shannon, Simpson, and Chao1 index) is used to assess the richness and diversity of microbial species within samples. (D) Bar chart of the top 10 species in terms of relative abundance at the family level. The horizontal axis represents samples, and the vertical axis represents relative abundance. “Others” indicates the sum of the relative abundances of all families not included in these top10. (E) Five families with significant differences. Values are presented as means ± SEM (n = 4).
