Overview

  • Bifidobacterium myosotis is a Gram-positive, non-spore-forming, anaerobic, non-motile, pleiomorph rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 65.1%. Bifidobacterium myosotis is probably a rare gut coloniser. (Michelini2016b)



  • This organism has been recovered from faeces of the common marmoset. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
