Overview

  • Deinococcus geothermalis is a Gram-positive, non-spore-forming, aerobic, non-motile, tetrad bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 65.9%. Deinococcus geothermalis is unlikely to be a gut coloniser. (Ferreira1997)



  • This organism has been recovered from hotsprings. 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
  • High optimum growth temperature so likely not a gut coloniser.
