Differences in dominant microorganisms between the TNBS and TNBS + MSCgroups. The TNBS group had higher enrichment of the Proteobacteria phylum, while the TNBS + MSC group had higher enrichment of the Firmicutes phylum a LDA scores from LefSe analysis were obtained from the relative OTU abundances and the least discriminant analysis (LDA) effect size taxonomic cladogram comparing all samples categorized by TNBS (red) and the TNBS + MSC group (blue). b Distribution histogram based on LDA (LDA score > 3). Significantly discriminant taxon nodes are coloured and the branch areas are shaded according to the highest-ranked variety for that taxon. For each taxon detected, the corresponding node in the taxonomic cladogram is coloured according to the highest-ranked group for that taxon. If the taxon is not significantly differentially represented between the sample groups, the corresponding node is depicted in yellow
