Overview

  • Kingella denitrificans is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, short rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 54.1-54.8%. Kingella denitrificans is likely to be transient and not a long-term gut coloniser. (Snell1976)



  • This organism has been recovered from respiratory tract. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. Likely to be transient and not a long-term gut commensal.
