Overview


  • Bifidobacterium imperatoris is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 56.1%. Bifidobacterium imperatoris is probably a rare gut coloniser. (Lugli2018)



  • Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
