Eubacterium rectale (E. rectale), which accounts for up to 13% of the gut microbiota in total feces in the human colon and thus, is one of the most prevalent bacterial species, is a major contributor to the production of butyrate. People with Crohn’s disease, rheumatoid arthritis (RA), and ulcerative colitis have significantly reduced amounts of Eubacterium rectale, and these people have lower butyrate concentrations in their feces than healthy individuals.
