Overview

  • Enterococcus moraviensis is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, coccus bacterium. The DNA G+C content is 36.3%. Enterococcus moraviensis is probably a rare gut coloniser. (Svec2011Bergey; Rossi2016)



  • This organism has been recovered from spring water. 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.
