Overview

  • Citrobacter pasteurii is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 51.80%. Citrobacter pasteurii is probably a rare gut coloniser. (Clermont2015)



  • This organism has been recovered from human faeces (diarrhoea patient - Clermont2015). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
