Overview


  • Corynebacterium kroppenstedtii is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, diphtheroidal bacterium. It has been detected in at least 7 gut microbiome compilation studies or metastudies. The DNA G+C content is 62%. Corynebacterium kroppenstedtii is probably a common, although minor, coloniser of the gut. (Collins1998; Bernard2012Bergey)



  • This organism has been recovered from clinical sources (wound, sputum - CCUG) and human faeces. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). It is an opportunistic pathogen. A possible gut commensal.
