Overview

  • Micrococcus cohnii is a Gram-positive, non-spore-forming, aerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 70.4%. Micrococcus cohnii is likely to be transient and not a long-term gut coloniser. (Rieser2013)



  • This organism has been recovered from human faeces and air sample. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
