Overview


  • Listeria grayi is a Gram-positive, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 41-42.5%. Listeria grayi is probably a rare gut coloniser. (Rocourt1992; Wilkinson1977; Orsi2016; Mclauchlin2011Bergey)



  • This organism has been recovered from human faeces (CCUG), clinical sources, food and vegetation. 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.
