Overview

  • Shuttleworthia satelles is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped - curved bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 51%. Shuttleworthia satelles is probably a rare gut coloniser.



  • This organism has been recovered from the human oral cavity. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
