Overview

  • Enterococcus haemoperoxidus is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, oval-shaped bacterium. The DNA G+C content is 35.3-35.5%. Enterococcus haemoperoxidus is probably a rare gut coloniser. (Svec2011Bergey; Rossi2016)



  • This organism has been recovered from surface waters. 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.
