Overview


  • Virgibacillus proomii is a Gram-positive, spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 37%. Virgibacillus proomii is probably a rare gut coloniser. (Heyndrickx1999; Heyrman2011Bergey)



  • This organism has been recovered from human faeces (Hoyles2012), soil and clinical sources (infant bile). 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.
