PcFMT recovered the microbiota community structures of S. Typhimurium-induced colitis mice. The microbiota of fresh faeces collected from healthy, bacteria-infected, single-dose Pc-treated, FMT-treated, and PcFMT-treated mice were detected by amplifying the V3–V4 region of the 16S rRNA gene using specific primers (Nobar_341F-805R). Relative abundance of predominant bacteria at the phylum (A) level and genus (B). “Unt” represents the untreated healthy mice group; “Bai” represents the bacterial-infected mice group; “Pc” means the phage cocktail-treated mice group; “PcFMT” represents the combined phage cocktail and FMT mice group. Data are expressed as the means ± SEM, n = 6. *P < 0.05; **P < 0.01.
