Overview

  • Campylobacter jejuni subsp. doylei is a Gram-negative, non-spore-forming, microaerophilic, motile, rod-shaped - curved bacterium. The DNA G+C content is 29%. Campylobacter jejuni subsp. doylei is probably a rare gut coloniser. (Steele1988; Vandamme1991; VanDamme2005Bergey)



  • This organism has been recovered from clinical sources and human faeces (young girl with diarrhoea - CCUG). 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.

    Campylobacter jejuni ICDCCJ07001 (HS:41, ST2993) was isolated from a Guillain-Barré syndrome (GBS) patient during a 36-case GBS outbreak triggered by C. jejuni infections in north China in 2007.[PMID: 21124772]
