Key Features:

1. Comprehensive Identification:
   • Detects and differentiates Staphylococcus spp. of clinical significance.
   • Covers a wide range of species, including S. aureus, S. epidermidis, S. hominis, S. saprophyticus, and others.
2. 18 Biochemical Tests:
   • Tests include arginine decarboxylation (ADC), urea hydrolysis (UR), maltose fermentation (MAL), and others.
   • Special tests requiring reagents include VP test, nitrate test, and others.
3. Ready-to-Use System:
   • Each system contains pre-measured and pre-dried biochemical substrates, eliminating preparation time.
4. Convenient Coding System:
   • Generates a 6-digit code based on positive and negative reactions.
   • Easily identifies microorganisms using the included code number table.
5. Rapid Workflow:
   • Results available within 18-24 hours, enabling quick diagnostic decisions.
6. Quality Control Tested:
   • Each batch is validated with reference strains, ensuring reliable and reproducible results.

Contents:

Required but Not Included:

• Vaseline Oil (ref. 80279)
• Nitrate Test Reagent (ref. 88009)
• VP Test Reagent (ref. 80280)

Biochemical Tests:

Procedure:

1. Prepare Bacterial Suspension:
   • Isolate the microorganism on selective agar (e.g., Baird Parker Agar, Vogel Johnson Agar).
   • Suspend colonies in physiological solution to achieve 1-2 McFarland turbidity.
2. Inoculate the System:
   • Transfer 0.2 mL (4 drops) of bacterial suspension into each well.
   • Add vaseline oil to wells 1-ADC and 2-UR.
   • Place xylose and ribose discs in wells 10-XYL and 15-RIB.
3. Incubate:
   • Cover the system and incubate at 36 ± 1°C for 18-24 hours.
4. Interpret Results:
   • Add reagents to specific wells (e.g., VP and NIT tests).
   • Note color changes and use the results to generate a 6-digit code.
   • Identify the microorganism using the code number table.

Storage and Handling:

• Store at 2°C to 8°C in its original container.
• Avoid heat and excessive temperature fluctuations.
• Do not use beyond the labeled expiration date.
