(A), the relative abundance of intestinal microbiota at the phylum level; (B), Proteobacteria; (C), Bacteroidetes; (D), Firmicutes; (E), Actinobacteria. (F), the relative abundance of intestinal microbiota at the genus level; (G), Acinetobacter; (H), Bifidobacterium; (I), Bacteroides; (J), Faecalibacterium. PB, probiotic group 3 days before bowel preparation (n = 16); PM, control group during bowel preparation (n = 16); PA, probiotic group 5–7 days after bowel preparation (Supplement the Bifidobacterium Tetragenous viable Bacteria Tablets after colonoscopy for up to 5–7 days, three tablets and three times a day) (n = 16).
