Overview

  • Cedecea lapagei is a Gram-negative, 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 48-52%. Cedecea lapagei is probably a rare gut coloniser. (Grimont1981; Farmer2005Bergey)



  • This organism has been recovered from human faeces (Alkhalil2017 - ulcerative colitis patient), respiratory tract (throat, sputum) and ticks. 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.
