Overview

  • Pseudocitrobacter anthropi 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 57.1%. Pseudocitrobacter anthropi is probably a rare gut coloniser. (Kaempfer2014; Kaempfer2020)



  • This organism has been recovered from human faeces (Kaempfer2014). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
