Overview

  • Bacteroides mediterraneensis is a Gram-negative, non-spore-forming, 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 47.5%. Bacteroides mediterraneensis is a common gut coloniser. (Andrieu2018; Mailhe2016)



  • This organism has been recovered from human faeces (Andrieu2018). Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal.
