Figure 3. The change of community structure of gut microbiota after ABX treatment. (A–C) The α-diversity of gut microbiota is represented by Chao1, Simpson, and Shannon index in pre-ABX and ABX group mice. (D) The β-diversity of gut bacterial was represented by PCoA analysis between two groups. (E) The bar chart of most differentially abundant features at the Phylum level of gut microbiota in pre-ABX and ABX group mice. (n = 4 per group).
