Overview


  • Pseudoflavonifractor capillosus, (aka Bacteroides capillosus), is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 22 gut microbiome compilation studies or metastudies. The DNA G+C content is 60%. Pseudoflavonifractor capillosus is a common gut coloniser. (Carlier2010)



  • This organism has been recovered from human faeces. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. Is a known gut commensal.
