Fig.3From: Commensal bacteria-derived extracellular vesicles suppress ulcerative colitis through regulating the macrophages polarization and remodeling the gut microbiotaEffects of C. butyricum-derived EVs on overall structural modulation of gut microbiota in DSS-induced colitis mice. a Venn diagram showed the differential numbers of OTUs in each group. b PCoA analysis based on unweighted UniFrac distances indicated a prominent site-specific clustering with the different groups. c NMDS analysis. d Hierarchical clustering tree of gut microbiota based on weighted Unifrac metrics indicated the different beta diversity of gut microbiota in each groupBack to article page
