Overview

  • Parabacteroides provencensis is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. The DNA G+C content is 40.8%. Parabacteroides provencensis is probably a rare gut coloniser. (Benabdelkader2020)



  • This organism has been recovered from human faeces (healthy). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
