Overview

  • Selenomonas sputigena is a Gram-negative, non-spore-forming, strictly anaerobic, motile, rod-shaped - curved bacterium. It has been detected in at least 5 gut microbiome compilation studies or metastudies. The DNA G+C content is 57%. Selenomonas sputigena is probably a rare gut coloniser. (Shouche2011Bergey)



  • This organism has been recovered from oral flora. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
