Overview

  • Eisenbergiella tayi is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 5 gut microbiome compilation studies or metastudies. The DNA G+C content is 46.0%. Eisenbergiella tayi is a common gut coloniser. (Amir2014)



  • This organism has been recovered from human blood and human faeces. Can cause opportunistic infections, particularly in immunocompromised people. Is a known gut commensal.
