AFNOR Approval RAPID'Staph: 24 hr Enumeration of Coagulase-Positive Staphylococci and S. aureus
 | Bio-Rad has extended its range of products for the isolation, enumeration and identification of staphylococci to include RAPID´Staph. This selective agar medium has recently been approved by AFNOR, according to ISO 16140 protocol, for the 24 hr enumeration of coagulase-positive staphylococci at 37 °C, including Staphylococcus aureus, in food and environmental samples.
Characteristic growth of coagulase-positive staphylococci on RAPID´Staph is shown as grey-black colonies surrounded with a clear halo. Sulphamethazine prevents high levels of Proteus contamination; lithium chloride and potassium telllurite inhibit growth of other bacteria. The optimized peptone formula improves growth and suits nutritional demands of Staphylococcus.
| Characteristic colonies of on RAPID´Staph are confirmed by using a validated procedure using Bio-Rad´s PASTOREX™ Staph-Plus latex agglutination test for detection of Staphylococcus aureus, or by spot on Baird Parker R.P.F. agar plates, or by means of a rabbit plasma coagulase test.
KEY BENEFITS:
- easy reading and enumeration of colonies
- a much lower cost, compared with Baird Parker R.P.F. agar
- easy confirmation, saving time and money, compared with ISO 888-1
- more selective than Baird Parker Egg Yolk Agar
- shorter time to result (24 hr) and rapid confirmation, when compared with Baird Parker Egg Yolk Agar (48-72 hr) | RAPID´Staph
