Overview

  • Enterococcus thailandicus, (aka Enterococcus sanguinicola), is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, oval-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 37.9%. Enterococcus thailandicus is probably a rare gut coloniser. (Shewmaker2011; Tanasupawat2008; Carvalho2004)



  • This organism has been recovered from fermented sausage, clinical sources (blood - CCUG) human faeces (Bilen2018e). The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
