Overview

  • Desulfomicrobium orale is a Gram-negative, non-spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 59.7%. Desulfomicrobium orale is likely to be transient and not a long-term gut coloniser. (Langendijk2001)



  • This organism has been recovered from subgingival dental plaque. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Is a rare opportunistic pathogen. Likely to be transient and not a long-term gut commensal.
