Fecal Microbiome Does Not Represent Whole Gut Microbiome

Figure 3

Relative abundances of sequences belonging to different families in the GI tracts. (a) The relative abundance of families at 14 locations of GI tract and feces. (b) The boxplots of the most abundant families for all through samples. Plot color represents the phylum level of families. The sampling locations within the GI tract were determined based on the anatomical feature: the stomach, the duodenum (small intestine_1), the jejunum (small intestine_2 ~ small intestine_5), the ileum (small intestine_6), the cecum (large intestine_1), the colon (large intestine_2 ~ large intestine_6), and the rectum (large intestine_7). The anatomical differences between each location are shown in Figure S1.
