Fecal Microbiome Does Not Represent Whole Gut Microbiome

Figure 6

Cooccurrence network analysis of gut microbiome at the stomach (a), the small intestine (b), the large intestine (c) of the GI tract, and feces (d) with the ReBoot algorithm. The colored shapes represent network communities determined by the Louvain modularity algorithm. Node colors and labels represent phyla. (e) The network information of the gut microbiome at the stomach, the small intestine, the large intestine, and feces. OTU: the numbers of OTUs used for network analysis. Node: node numbers. Edge: edge number. Modularity: modularity number. The network was developed by using species-level OTUs.
