Overview


  • Cellulomonas denverensis is a Gram-positive, non-spore-forming, aerobic, motile, short rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 68.5%. Cellulomonas denverensis is probably a rare gut coloniser. (Brown2005; Stackebrandt2012Bergey)



  • This organism has been recovered from clinical sources (blood - CCUG) and human faeces. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). Is a rare opportunistic pathogen. A possible gut commensal.
