Overview

  • Listeria ivanovii 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 36–38%. Listeria ivanovii is probably a rare gut coloniser. (Boerlin1992; Seeliger1984; Orsi2016; Mclauchlin2011Bergey)



  • This organism has been recovered from human faeces (McLauchlin2011Bergey), clinical sources and is pathogenic to animals. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Could be a possible pathogen in humans, but unknown at this stage. Is a known gut commensal.
