α- and β-diversity of intestinal microbiota. (a and b) PD-whole tree and observed species analysis. The black line in the middle of the rectangle in every group represents the median. (c and d) The more similar the composition of different samples in the PCoA analysis and NMDS analysis plot is, the closer the position in the plot is. The plot indicates that there is a significant community difference among the three groups. (e) The Venn diagram shows the common and different intestinal microbiota of the three groups.
