Overview

  • Spirochaeta coccoides is a Gram-negative, non-spore-forming, anaerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 56.6-57.4%. Spirochaeta coccoides is probably a rare gut coloniser. (Droge2006)



  • This organism has been recovered from a termite hindgut. 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.
