Pseudomonas aeruginosa · Quantitative QC strain
Pseudomonas aeruginosa Quantitative QC Strain – high count for productivity tests
The Pseudomonas aeruginosa Quantitative QC Strain 10^6 contains a high, defined number of cells. It is used where higher inocula are needed, for example for productivity ratios and method validation.
- Defined count: 0.6–2.0 × 10^7 CFU per vial
- For productivity ratios and validation
- Rehydration fluid included
How Pseudomonas aeruginosa Quantitative QC is used
After rehydration with 2 mL of fluid, 0.1 mL contains about 0.3–1.0 × 10^6 CFU. Tenfold dilutions in saline give the working inoculum for the test.
Technical data
| Preparation | Add 2 mL rehydration fluid, shake 5 s; 0.1 mL contains about 0.3–1.0 × 10^6 CFU |
| Storage | −18 °C or below; rehydrated suspension 2–8 °C, use within 8 h |
| Shelf life | 18–24 months |
Applications and practical notes
Pseudomonas aeruginosa reference strains are used for growth-promotion tests of selective media, in pharmacopoeial microbiological tests and for media testing according to ISO 11133. Typical applications include:
- Growth-promotion testing of CN, Cetrimide and chromogenic media
- Pharmacopoeial tests for specified micro-organisms
- Positive controls for P. aeruginosa methods
- Method verification and proficiency testing
Working with Pseudomonas aeruginosa Quantitative QC: Prepare the dilutions on the day of use and record the count with its confidence interval.
Good practice with rapid tests: store the kit as stated on the label, let the components reach room temperature before use and use each item only once. Record the lot number and the result, and confirm positive results according to the reference method when this is required.
About the Pseudomonas methods: ISO 16266 describes the detection and enumeration of Pseudomonas aeruginosa in water by membrane filtration on CN agar, where blue-green colonies that produce pyocyanin are counted as confirmed and other typical colonies are confirmed with further tests. ISO 13720 gives the count of presumptive Pseudomonas spp. in meat and meat products on CFC agar at 25 °C. Pharmacopoeial tests for P. aeruginosa use Cetrimide Agar. COLO.Science offers media, supplements, rapid tests and QC strains for these methods.
