Fig. 2From: Ecological and network analyses identify four microbial species with potential significance for the diagnosis/treatment of ulcerative colitis (UC)Shared mucosal microbiome species between healthy individuals and UC patients at whole community, major phylum, and core/periphery species levels. Green bar represents observed shared OTUs (species), magenta bar represents expected shared OTUs with A1 algorithm, and purple bar represents expected shared OTUs with A2 algorithm. Asterisks (*) indicate that number of observed shared OTUs between healthy individuals and UC patients was significantly smaller than expected by chance (p ≤ 0.05)Back to article page
