Overview

  • Enterococcus caccae is a Gram-positive, non-spore-forming, facultatively anaerobic, coccus bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 32.5%. Enterococcus caccae is probably a rare gut coloniser. (Carvalho2006; Svec2011Bergey; Rossi2016)



  • This organism has been recovered from human faeces. 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. Is a known gut commensal. Robust growth can have positive consequences for gut health.
