  • C. jejuni, spiral-shaped bacteria [Fig] well adapted to birds (carriage is asymptomatic).
    • Microaerophilic, member of Campylobacteriacae
  • Culture usually performed using selective "CAMP" agar, with the temperature set at normal avian body temperature of 42°C, rather than at 37°C.
    • Microaerophilic conditions facilitate growth.
    • Oxidase positive.
    • Stool Gram stain, curved rods suggestive of diagnosis (sensitivity 50-75%)
    • Typically only scanty growth seen on aerobic plates.
