🔹 Intended Use
For the enrichment culture of Clostridium chauvoei for blackleg vaccine manufacturing.
🔹 Core Product Features
- Enhanced with Liver Tissue: The inclusion of liver pieces provides complex nutrients and growth factors that significantly boost the proliferation of C. chauvoei.
- Optimized for Anaerobes: The formulation maintains a low redox potential, creating the ideal reducing environment required for strict anaerobic bacteria.
- Heat-Stable Formulation: The medium is designed to withstand autoclaving at 116°C for 40 minutes without degradation, ensuring consistent performance.
- High-Yield Performance: Promotes vigorous bacterial growth, resulting in high cell counts suitable for large-scale vaccine production.
🔹 Directions for Use
- Suspend 27.0 g of the base medium powder in 1000 mL of distilled water.
- Add an appropriate amount of liver pieces (typically 5-10% v/v) to the solution.
- Heat to boiling to completely dissolve the powder.
- Sterilize by autoclaving at 116°C for 40 minutes.
- Cool to room temperature under anaerobic conditions before use.
🔹 Microbial Sensitivity Test
Test Protocol: Inoculate the QC strain and incubate at 36±1°C for 18–24 hours under anaerobic conditions.
Test Results
| QC Strain | 9-Tube Method (Growth in Replicates) | Plate Count Method (CFU) |
|---|
| Clostridium chauvoei (Gas Gangrene Bacillus) | Control/Sample: Growth observed in all 3 replicates at dilutions 10⁻⁶, 10⁻⁷, and 10⁻⁸. | Control: TNTC (Too Numerous To Count) at 10⁻⁵ & 10⁻⁶; 63/66 at 10⁻⁷.Sample: TNTC at 10⁻⁵ & 10⁻⁶; 58/64 at 10⁻⁷. |
