highly significantP =0.001
Principal coordinate analysis (PCoA) based on Bray-Curtis distances showed a significant separation in microbial community structure between the three groups of mice (R 2 = 0.2055, P =0.002, Figure 3A ), with a highly significant separation in the C. jejuni group compared to the Control group (R 2 = 0.2275, P =0.001, Figure S1D ), and in the FMT group (R 2 = 0.1525, P =0.03, Figure S1E ) and the microbial community structure of the FMT group was not significantly separated compared to the Control group (R 2 = 0.1059, P =0.127, Figure S1F ), thus indicating that the FMT preparation worked to regulate the structure of the intestinal flora that had been altered by the influence of C. jejuni and to restore it to normal.
