How It Works:
- Sample Preparation:
- Prepare bacterial suspension using the Listeria System 18R protocol.
- Biochemical Testing:
- Add the appropriate reagents to specific wells of the Listeria System 18R as per instructions:
- Add Alpha Naphtol and NaOH 40% to Well 18-VP for the Voges-Proskauer test.
- Add Hydrogen Peroxide to Well 6-CAT for the Catalase test.
- Add Kovac's Reagent to Well 4-IND for the Indole test.
- Add Sulphanilic Acid and Alpha Naphthylamine to Well 17-NIT for the Nitrate Reduction test.
- Add Methyl Red to Well 7-MR for the Methyl Red test.
- Add the appropriate reagents to specific wells of the Listeria System 18R as per instructions:
- Result Interpretation:
- Observe color changes or gas formation in the wells to interpret results:
- Positive reactions for biochemical tests are indicated by specified color changes or bubbles.
- Observe color changes or gas formation in the wells to interpret results:
