Overview

  • Yersinia kristensenii subsp. kristensenii is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 48.5%. Yersinia kristensenii subsp. kristensenii is probably a rare gut coloniser. (Bercovier1980a)



  • This organism has been recovered from soil, food, clinical sources (rare) and 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: zoonotic pathogen). It is an opportunistic pathogen. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Although the bacterium can be found in faeces, it requires cold enrichment to grow. This suggests it won't be a significant coloniser of the gut.
