Characterization of the human gastrointestinal virome in recipients before and after FMT and in donors. (A) Relative abundances of viral taxa in the fecal samples from 9 patients who underwent FMT. B: before FMT; A: after FMT; D: donor. (B) Comparison of the relative abundance in viral taxa between samples obtained from recipients before and after FMT. *P < .05, ***P < .001, paired Student t test. (C) Richness of the viral contigs in the viral fraction in samples obtained from recipients before and after FMT (n = 9). (D) Alpha diversity of the viral contigs in the viral fraction from samples obtained from recipients before and after FMT (n = 9). (E) Alpha diversity and richness of Caudovirales viral contigs in samples obtained from recipients before and after FMT (n = 9). (F) Alpha diversity and richness of Microviridae viral contigs in samples obtained from recipients before and after FMT (n = 9). *P < .05, **P < .01, paired Student t test. (G) Alpha diversity and richness of crAss-like phage viral contigs in samples obtained from recipients before and after FMT (n = 9 patients). **P < .01, paired Student t test. (H) Bray–Curtis dissimilarity of the virome communities at the contig level between pre-FMT and donor samples, between post-FMT and donor samples, and between pre- and post-FMT samples (n = 9). **P < .01, paired Student t test. Boxplots were drawn using R with the default parameter setting.
