Overview

  • Klebsiella quasipneumoniae subsp. quasipneumoniae is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 55.9%. Klebsiella quasipneumoniae subsp. quasipneumoniae is probably a common, although minor, coloniser of the gut. (Brisse2014)



  • This organism has been recovered from clinical sources (blood). It is an opportunistic pathogen. A possible gut commensal.
    • QUIRKS
  • In 10% of Europeans (unseenbio.com). Minor coloniser.
