Modulation of an IBD-associated Th17-inducing strain following microbiota transplant. (A) The mean relative abundance of E. coli strain A6 from donor IBD A in mice before and at three time points after DMT with one of five HD microbiotas. (B) The correlation between the relative abundance of E. coli strain A6 and the proportion of RORγt⁺ Th17 cells in mice colonized with IBD A alone or following transplant with each of the five HD microbiotas. *P < 0.05, ****P < 0.0001 as calculated by ANOVA with Tukey correction comparing the relative abundance of the strain before transplant and at each time point after transplant. P value in B calculated by f-test.
