Overview

  • Campylobacter fetus subsp. fetus is a Gram-negative, non-spore-forming, microaerophilic, motile, rod-shaped - curved bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 33-36%. Campylobacter fetus subsp. fetus is probably a rare gut coloniser. (Vandamme1991; Veron1973; VanDamme2005Bergey)



  • This organism has been recovered from human faeces, clinical sources (blood - CCUG), and human gut. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: zoonotic pathogen). Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
