Overview

  • Escherichia ruysiae is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. Escherichia ruysiae is probably a rare gut coloniser. (vanderPutten2021)



  • This organism has been recovered from a European with diarrhoea after travelling through Asia. Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
    • QUIRKS
  • The organism was lost from the patient's gut after less than one month
