Differentially abundant bacteria in the luminal content flora, inner mucus layer flora, and outer mucus layer flora of UC model group. a. Venn diagram shows the differentially abundant bacteria in the luminal content flora, inner mucus layer flora, and outer mucus layer flora of UC model group; b. Ternary diagram showed the differentially abundant bacteria in the luminal content flora, inner mucus layer flora, and outer mucus layer flora of UC model group; c. The distribution histogram in LDA value showed the differentially abundant bacteria in the luminal content flora, inner mucus layer flora, and outer mucus layer flora of UC model group. LDA bar graphs of taxa/clades that are differentially abundant in the luminal content (red), inner layer (green) and outer mucus layer (blue) of the model group. Taxa in this graph were both statistically significant(P < 0.05) and had an LDA Score > 2, considered a significant effect size. *MC: the luminal content of the model group. MO: the outer mucus layer of the model group. MI: the inner mucus layer of the model group
