Overview

  • Bacteroides acidifaciens is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 5 gut microbiome compilation studies or metastudies. The DNA G+C content is 39.4-42.2%. Bacteroides acidifaciens is a common gut coloniser. (Miyamoto2000)



  • This organism has been recovered from mouse caeca and human faeces (Bilen2018e). The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
