Overview

  • Bifidobacterium pseudolongum subsp. globosum, (aka Bifidobacterium globosum), is a Gram-positive, non-spore-forming, anaerobic, non-motile, coccobacillus bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 64.5%. Bifidobacterium pseudolongum subsp. globosum is probably a rare gut coloniser. (Biavati1982; Scardovi1969)



  • This organism has been recovered from human faeces and animal faeces. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
