SLC9A3 and colitis: Statistical (ANOSIM) and visual (PCoA) comparisons of unweighted UniFrac distances between gut microbiome samples indicated that NHE3 deficiency was the single most significant factor associated with microbial dysbiosis, and that despite very strong inflammatory response to the adoptive T cell transfer, within the 13 day time frame of the study, fecal microbial ecology was not significantly affected by the developing colitis.
