Overview


  • Bifidobacterium cuniculi is a Gram-positive, non-spore-forming, strictly 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 64.1%. Bifidobacterium cuniculi is probably a rare gut coloniser. (Scardovi1979)



  • This organism has been recovered from rabbit 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.
