Overview

  • Enterococcus canis is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, oval-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 41.7-43.0%. Enterococcus canis is probably a rare gut coloniser. (Svec2011Bergey; DeGraef2003)



  • This organism has been recovered from dog faeces. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). Can cause opportunistic infections, particularly in immunocompromised people. A possible gut commensal.
