Overview


  • Bifidobacterium pullorum subsp. gallinarum, (aka Bifidobacterium gallinarum), is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, rod-shaped - curved bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 65.7%. Bifidobacterium pullorum subsp. gallinarum is probably a rare gut coloniser. (Watabe1993)



  • This organism has been recovered from caeca of chickens. Also from human faeces (Alkhalil2017). 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.
