-  "overview": "Eubacterium is a genus of strictly anaerobic, Gram-positive to gram-variable, non-spore-forming rods commonly found in the human gastrointestinal tract. Species of Eubacterium participate extensively in fermentation of dietary fiber and production of short-chain fatty acids, particularly butyrate and acetate. While generally commensal, some species may translocate or contribute to dysbiosis-associated diseases.",
