Overview

  • Enterococcus pseudoavium is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, coccus bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 40%. Enterococcus pseudoavium is probably a rare gut coloniser. (Collins1989a; Svec2011Bergey)



  • This organism has been recovered from human faeces, clinical sources (blood) and bovine mastitis. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: animal pathogen). Is a rare opportunistic pathogen. A possible gut commensal.
