Overview

  • Yersinia intermedia is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 48.5%. Yersinia intermedia is probably a rare gut coloniser. (Brenner1980b)



  • This organism has been recovered from aquatic systems, rarely terrestrially or in humans. Found in human faeces and clinical sources (blood) and food.. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: zoonotic pathogen). It is an opportunistic pathogen. A possible gut commensal.
    • QUIRKS
  • Unlikely to be pathogenic. Most clinical isolates are clusters and seem unrelated to the illnesses of the patients. In 2% of healthy Europeans (unseenbio.com)
