Overview

  • Eubacterium ventriosum, (aka Bacteroides ventriosus), is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 25 gut microbiome compilation studies or metastudies. Eubacterium ventriosum is often a widespread coloniser of gut. (Wade2011aBergeys; Eggerth1935)



  • This organism has been recovered from human faeces and clinical sources (mouth abscess, various infections). The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. Is a known gut commensal.
