Campy CVA Agar
Selective Blood Agar with Cefoperazone, Vancomycin & Amphotericin B for Campylobacter Isolation
Campy CVA Agar is a highly selective medium designed for the isolation of Campylobacter spp., particularly C. jejuni and C. coli, from clinical, food, and environmental samples. The formulation combines a blood-enriched base with cefoperazone, vancomycin, and amphotericin B to suppress competing flora while supporting microaerophilic growth.

🔬 Principle of the Medium
Campy CVA Agar combines a nutrient-rich blood agar base with selective antibiotics:
- Cefoperazone → inhibits Gram-negative enterics
- Vancomycin → inhibits Gram-positive bacteria
- Amphotericin B → inhibits fungi
This combination creates a selective environment allowing Campylobacter spp. to grow under microaerophilic conditions (reduced oxygen, increased CO₂).
CVA antibiotics → suppress flora
↓
Microaerophilic incubation → Campylobacter growth

Microaerophilic incubation → Campylobacter growth
🧪 Applications
- Isolation of Campylobacter jejuni and C. coli
- Food safety testing (especially poultry)
- Clinical stool samples
- Environmental monitoring
📊 Campylobacter Media Comparison
| Medium | Selectivity | Antibiotics | Best Use |
|---|---|---|---|
| Campy CVA Agar | High | Cefoperazone + Vancomycin + Amphotericin | Routine isolation |
| Campy-BAP | Moderate–High | Mixed antibiotic system | Clinical labs |
| Skirrow Medium | Moderate | Vancomycin + polymyxin | Traditional method |
| Modified CCDA | Very high | Cefoperazone-based | Food testing (ISO) |
💡 Practical Notes
- Requires microaerophilic incubation (5% O₂, 10% CO₂)
- Use fresh blood supplementation
- Incubate at 42°C for optimal Campylobacter growth
- Highly selective – may inhibit stressed cells
