How Skirrow Agar Supplement works
The antibiotic mixture suppresses Gram-positive bacteria, Enterobacteriaceae and Pseudomonas, so that Campylobacter can grow on the blood agar in a microaerobic atmosphere.
Technical data
| Use | Dissolve in 1 mL sterile water; 1 vial and 5 mL defibrinated sheep blood per 100 mL Skirrow Agar Base at about 45 °C |
| Storage | 2–8 °C |
Applications and practical notes
Campylobacter is the most frequently reported cause of bacterial gastroenteritis in Europe and is tested in poultry, meat, milk and water according to ISO 10272-1. Typical applications include:
- Poultry meat and carcass rinses
- Raw milk and dairy products
- Drinking and surface water
- Environmental and faecal samples
Working with Skirrow Agar Supplement: Dissolve the vial in 1 mL of sterile water and add it with the blood to the base cooled to about 45 °C.
Good practice with media and supplements: keep the bottle tightly closed in a cool, dry place, weigh the powder quickly to avoid moisture uptake, and use fresh distilled or deionised water. Check the pH of each new batch after preparation and before use, and label prepared media with the date. Performance of each lot can be verified with reference strains according to ISO 11133, the standard for the preparation, production, storage and performance testing of culture media.
About the Campylobacter method: ISO 10272-1 describes the detection of thermotolerant Campylobacter in food and feed. Samples with low numbers and stressed cells are enriched in Bolton broth, samples with high background flora in Preston broth. Enrichment cultures are plated on mCCD agar and a second selective agar of the laboratory’s choice and incubated microaerobically at 41.5 °C. Typical colonies are confirmed by morphology, motility, oxidase and further tests. COLO.Science offers supplements, media and latex kits for these steps.
