Overview


  • Eubacterium callanderi is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 47%. Eubacterium callanderi is probably a common, although minor, coloniser of the gut. (Mountfort1988; Wade2011Bergeys)



  • This organism has been recovered from human faeces, and an anaerobic digester. 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.
