The diversity of gut microbiota changes in the dysbiosis mouse model. A The experimental design of dysbiosis model. C57BL/6J mice were treated with ceftriaxone and followed by treatments (AC, FMT, FMT + AC, FF, and FF + AC) for 7 consecutive days. B Alpha diversity (observed species, Chao1, Shannon, and PD whole tree) by 16 S rRNA gene sequencing in the feces from different experimental treatment groups at pre-condition versus day 7 (n = 3–8 per group). C PCoA on weighted UniFrac using the Bray Curtis method on 16 S rRNA gene sequencing of fecal microbiota from different treatment groups at pre-condition versus day 7(n = 3–8 per group). All experimental data were representative of two independent experiments. Statistics were done using the Kruskal-Wallis test (B) and the Permutational multivariate analysis of variance (PERMANOVA) test (C). *p < 0.05, **p < 0.01.
