Overview


  • Enterobacter ludwigii is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 5 gut microbiome compilation studies or metastudies. Enterobacter ludwigii is probably a rare gut coloniser. (Hoffmann2005b)



  • This organism has been recovered from human faeces (Alkhalil2017 - ulcerative colitis patient) and blood. 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.
