Overview

  • Corynebacterium casei is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, pleiomorph rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 51%. Corynebacterium casei is probably a rare gut coloniser. (Brennan2001b)



  • This organism has been recovered from the surface of a smear-ripened cheese. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
