【 Principle 】

Meat extract, animal tissue hydrolysate, and casein hydrolysate provide carbon, nitrogen, vitamins, and growth factors; Sodium chloride maintains a balanced osmotic pressure; Charcoal has the functions of detoxification, collecting carbon dioxide, and changing surface tension; Sodium deoxycholate is a selective antibacterial agent; Cefoperazone can inhibit the growth of common intestinal bacteria, amphotericin B can inhibit the growth of yeast and fungi, and rifampicin can inhibit non curved bacteria and other anaerobic bacteria; Ferrous sulfate and sodium pyruvate are beneficial for the growth of Campylobacter jejuni; Agar is a coagulant for culture media.

Main components

Campylobacter jejuni, Campylobacter coli

Biological characteristics: G-shaped, S-shaped, seagull spreading wings, single flagella at one or both ends, active movement; Strictly microaerophilic (5% O ₂, 10% CO ₂, 85% N ₂), suitable for growth at 42 ℃, weak at 37 ℃, and no growth at 25 ℃; Oxidase+, peroxidase+; Campylobacter jejuni hydrolysis of uric acid+, Campylobacter coli -; Non fermentable sugars, no H ₂ S. zoonotic diseases, with poultry as the main host; Triggering acute enteritis can lead to secondary Guillain Barr é syndrome.

Improved CCD agar culture characteristics: 42 ℃, 24-48 hours; colonies are small, flat, moist, gray white/semi transparent, with irregular edges, appearing as water droplets or misty films; Typical moldy or slightly acidic odor; Smear shows characteristic S-shaped and arc-shaped G ⁻ bacilli, with active motility; The miscellaneous bacteria are effectively suppressed, the plate is clean, and the target bacteria are dominant colonies.
