Overview

  • Blautia glucerasea is a Gram-positive, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 40.7%. Blautia glucerasea is probably a rare gut coloniser. (Furuya2010)



  • This organism has been recovered from human faeces, and dog faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
