Overview

  • Eubacterium infirmum is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 6 gut microbiome compilation studies or metastudies. The DNA G+C content is 38%. Eubacterium infirmum is probably a rare gut coloniser. (Cheeseman1996)



  • This organism has been recovered from human faeces (Bilen2018e) and peridontal pockets. 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. Likely to be transient and not a long-term gut commensal.
