Overview


  • Phocaeicola barnesiae, (aka Bacteroides barnesiae), is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 7 gut microbiome compilation studies or metastudies. The DNA G+C content is 46.8%. Phocaeicola barnesiae is a common gut coloniser. (Lan2006)



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

  • QUIRKS
