Overview


  • Citrobacter gillenii, (aka Citrobacter genomospecies 10), is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. Citrobacter gillenii is probably a rare gut coloniser. (Brenner1999; Friederiksen2005Bergey)



  • This organism has been recovered from human faeces, urine, clinical sources and the environment. 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. A possible gut commensal.
