FIG 2.

The gut microbiota is affected by diseases. The figure illustrates the all-species living tree highlighting all clades for which gut microbial isolates have been obtained (archaea are presented in yellow, and bacteria are in blue). Collapsed clades illustrate phyla, and colored boxes include the archaeal/bacterial orders. Order-level taxa that have been reported to be influenced mainly by disease are indicated in boldface. Database obtained from “The All-Species Living Tree” Project (https://www.arb-silva.de/projects/living-tree/). Information about the microbiome isolates was obtained from both the Human Microbiome Project (http://www.hmpdacc.org/; 103) and the MetaHIT (http://www.metahit.eu/; 43, 104, 105) initiatives.
