Gut microbial diversity of bile acid metabolizers, SCFA producers, and sporulators. The α-diversity (Shannon index) of (A) bile acid metabolizers, (B) SCFA producers, and (C) sporulating bacteria of donors, recipients pre- and post-FMT for successful and failed FMT outcomes. Significant differences were determined using the Kruskal–Wallis and Wilcoxon signed-rank tests for unpaired and paired samples, respectively, followed by the Bonferroni post-hoc correction. Adjusted p-values were defined at *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001. The Beta diversity was also calculated using the Bray–Curtis distance-based density plots (D–F) and analyzed using ANOSIM.
