Fig. 3: Microbiome composition among seven surface organs.

A1 Abundances of six major phyla in seven organs: Proteobacteria (relative abundance: 41.31% ± 9.63%, Mean ± SD), Firmicutes (35.02% ± 8.36%), Bacteroidetes (14.10% ± 8.30%), Actinobacteria (6.21% ± 5.46%), Fusobacteria (1.65% ± 1.80%), and Tenericutes (0.37% ± 0.83%). A2 Phylum with significantly different abundance among seven organs by ANCOM-BC2 method (n = 328, 198, 110, 150, 363, 32, 427 for skin, oral cavity, esophagus, stomach, small intestine, appendix, and large intestine, respectively). B Genus with significantly different abundance among seven organs by ANCOM-BC2 method. The colormaps represents the average bacterial abundance. Data are shown as Box and whisker plots (A2) to represent the median (center line), quartiles (box), range (whiskers), and outliers (points outside 1.5 times the interquartile range). Source data are provided as a Source Data file.
