Structural comparison of fecal microbiota among the four groups. A and B Observed OTUs and Chao 1 index; Statistical analysis was performed using Tukey–Kramer post hoc test. Values are means ± SD (n = 6). C Principle coordinate analysis (PCoA) plot generated using OTU metrics based on the Bray–Curtis similarity for control, model, and PPd and TPd groups (n = 6 per group). D Hierarchical clustering based on the Bray–Curtis similarity of fecal microbial composition among all groups (n = 6 per group). E Linear discriminant analysis (LDA) effect size method was performed to compare taxa between control, model, and PPd and TPd group (n = 6 per group). The bar plot lists the significantly differential taxa based on effect size (LDA score (log 10) > 3). F Comparison of relative abundance at phylum, family, and genus levels among all groups (n = 6 per group). Data are expressed as mean ± SEM. Differences were assessed by the Mann–Whitney U test. Significance was established at adjusted P < 0.05 with a false discovery rate (FDR) of 0.05
