Rapid Presumptive Identification of PYRase-Producing Bacteria
The Thermo Scientific™ Remel™ PYR Disc with Reagent is a rapid enzymatic test designed for the presumptive identification of PYRase-positive bacteria, including Enterococcus spp., Streptococcus pyogenes (Group A streptococci), and Escherichia coli. This easy-to-use, colorimetric assay detects pyrrolidonyl arylamidase (PYRase) enzyme activity, a key biochemical marker in distinguishing these clinically important organisms. With results in just minutes, this test is ideal for clinical microbiology laboratories that require fast, reliable, and cost-effective diagnostics.
Key Features & Benefits
- Rapid Detection: Results available within minutes, facilitating timely treatment decisions
- Broad Clinical Coverage: Detects Streptococcus pyogenes (Group A), Enterococcus spp., and E. coli
- User-Friendly Format: Discs are pre-impregnated with substrate; simply add reagent and observe color change
- Clear Interpretation: A bright cherry-red color indicates a positive reaction
- Convenient Storage: Compact format, refrigerated at 2°C to 8°C
- Flexible Kit Sizes: Available in 25, 50, and 100 test configurations to suit varying lab volumes
How It Works
Each disc is impregnated with a PYR substrate. Upon application of the sample and reagent, the presence of PYRase enzyme triggers a rapid color reaction. A positive result is indicated by the development of a cherry-red color, while the absence of color change signifies a negative result.
Applications
- Clinical Microbiology: Fast screening of bacterial isolates for Group A Streptococcus, Enterococcus, and E. coli
- Hospital Diagnostics: Supports antimicrobial stewardship through accurate and rapid identification
- Teaching & Training: Ideal for use in microbiology education due to its simplicity and visual clarity
- Infectious Disease Labs: Useful in diagnostic workflows for urinary tract, throat, and wound infections
