Overview

  • Criibacterium bergeronii is a Gram-variable, non-spore-forming, anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 33.8%. Criibacterium bergeronii is probably a rare gut coloniser.



  • This organism has been recovered from a vaginal sample of a woman diagnosed with bacterial vaginosis. Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
