Distribution of abundant phyla among A) donor and pre-FMT samples, B) post-FMT samples from responders, and C) post-FMT samples from patients who had recurrence. Numbers in parentheses reflect the numbers of samples in each group. Letters on family abundances reflect significant differences by Tukey’s post hoc test (P < 0.05) across all groups (all panels) for each family, separately. No significant differences were observed for abundances of Porphyromonadaceae. Less abundant families represent those present at mean abundance ≤ 5% of sequence reads among all samples
