Overview

  • Rothia koreensis, (aka Kocuria koreensis), 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 65.2%. Rothia koreensis is probably a rare gut coloniser. (Park2010)



  • This organism has been recovered from traditional fermented seafood, Korea. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
