快速篩選顯色培養(yǎng)基，RAPID'Staph Medium is a selective agar used for the direct enumeration of coagulase-positive staphylococci (Staphylococcus aureus and other species) in products intended for human or animal consumption or in environmental samples.

Key Benefits

• Results in 24 hr after 24 hr of enrichment
• Highly selective and easy to read
• Choice of two methods for easy confirmation
• Certified NF VALIDATION according to the ISO 16140 standard and validated by AOAC

Principle

The principle of RAPID'Staph Medium is based on an optimized Baird-Parker formula to guarantee the detection and enumeration of S. aureus in 24 hr at 37°C. Typical staphylococci produce gray to black colonies that are shiny and convex (1–2 mm) with a clear 2–5 mm halo due to proteolysis of the egg yolk.

Presumptive colonies can be confirmed using one of the following methods:

• Pastorex™ Staph-Plus Latex Agglutination Test () with results within minutes
• Spot inoculation on Baird-Parker + RPF agar () to confirm many colonies on the same plate
