Question:

The recommended selective culture media to detect Campylobacter jejuni is ______.

Show Hint

Associate *Campylobacter* with "Charcoal" and "Cefoperazone" (mCCDA). It is the classic black agar used for isolating this microaerophilic pathogen.
  • Modified Charcoal Cefoperazone Deoxycholate Agar
  • Modified Charcoal Tetracycline Deoxycholate Agar
  • Modified Hektoen Enteric (HE) Agar
  • Xylose Lysin Desoxycholate Agar

The Correct Option is A

Solution and Explanation



Step 1: Understanding the Concept:

*Campylobacter jejuni* is a major foodborne pathogen responsible for bacterial gastroenteritis, often associated with undercooked poultry. It is microaerophilic and fastidious, requiring specialized selective growth media.

Step 2: Detailed Explanation:

- Modified Charcoal Cefoperazone Deoxycholate Agar (mCCDA) is the globally recognized selective medium recommended by ISO and FDA for isolating *Campylobacter* species.
- The charcoal acts as a detoxifying agent to scavenge toxic oxygen radicals, while the selective antibiotic cefoperazone inhibits competing Gram-negative enterics, and amphotericin B inhibits fungal growth.
- Hektoen Enteric (HE) and Xylose Lysine Deoxycholate (XLD) agars are selective media designed for *Salmonella* and *Shigella* detection, not *Campylobacter*.

Step 3: Final Answer:

The recommended selective medium for detecting *Campylobacter jejuni* is Modified Charcoal Cefoperazone Deoxycholate Agar (mCCDA).
