Overview

  • Coraliomargarita akajimensis is a Gram-negative, non-spore-forming, strictly 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 53.9%. Coraliomargarita akajimensis is unlikely to be a gut coloniser. (Yoon2007b)



  • This organism has been recovered from sea water, Japan. 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. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate aerobe and low optimum temperature suggest it is not a gut coloniser.
