Overview

  • Fusobacterium necrophorum subsp. funduliforme is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 27-31%. Fusobacterium necrophorum subsp. funduliforme is probably a rare gut coloniser. (Shinjo1991)



  • This organism has been recovered from pathogenic legions of animals. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). It is an opportunistic pathogen. A possible gut commensal.
