Overview


  • Listeria seeligeri is a Gram-positive, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 36%. Listeria seeligeri is probably a rare gut coloniser. (Rocourt1983; Orsi2016; Mclauchlin2011Bergey)



  • This organism has been recovered from human faeces (McLauchlin2011Bergey), soil and environment. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). Can cause opportunistic infections, particularly in immunocompromised people. Is a known gut commensal. Robust growth can have positive consequences for gut health.
