Overview

  • Eubacterium sulci, (aka Fusobacterium sulci), is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 39%. Eubacterium sulci is probably a rare gut coloniser. (Wade2011aBergeys; Cato1985)



  • This organism has been recovered from dental disease and human faeces. 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.
