Overview


  • Enterococcus durans, (aka Streptococcus durans), is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, oval-shaped bacterium. It has been detected in at least 15 gut microbiome compilation studies or metastudies. The DNA G+C content is 38-40%. Enterococcus durans is a common gut coloniser. (Collins1984; Svec2011Bergey; Rossi2016)



  • This organism has been recovered from human clinical sources (infection, blood), veterinary clinical materials, food, the environment, and human faeces. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). It is an opportunistic pathogen. Is a known gut commensal.
