Overview

  • Escherichia albertii is a Gram-negative, non-spore-forming, facultatively 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 50.5-50.7%. Escherichia albertii is probably a common, although minor, coloniser of the gut. (Huys2003)



  • 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 (notes: human and animal pathogen). It is an opportunistic pathogen. A possible gut commensal.
