a Chao1 and Shannon indexes indicative of community richness and diversity. n = 10/group. b Principal coordinate analysis based on weighted UniFrac distances of the relative abundances of bacterial OTUs after berberine treatment. n = 10/group. c Taxonomic distributions of bacteria at the phylum level. n = 10/group. d The F/B ratio in each group. n = 10/group. e Relative abundance of Firmicutes in each group. n = 10/group. f Relative abundances of selected genera enriched by berberine. n = 10/group. g Design of the FMT experiment. n = 5 (GW); n = 4 (GWB). h Fecal pellet output number in the container after acute WAS. i Abdominal withdrawal reflex scores in response to CRD. *P < 0.05, **P < 0.01, ***P < 0.001.
