Thermo Scientific™ Campylobacter Blood-Free Selective Agar Base (Dehydrated)
Description
Isolate Campylobacter jejuni, Campylobacter coli and Campylobacter laridis with Campylobacter Blood-Free Selective Agar Base .
Isolate Campylobacter jejuni, Campylobacter coli and Campylobacter laridis using Thermo Scientific™ Oxoid™ Campylobacter Blood-Free Selective Agar Base (Dehydrated) when used with CCDA Selective Supplement SR0155. Campylobacter Blood-Free Selective Agar Base is based on the original formulation described by Bolton et.al1 which was developed to replace blood with charcoal, ferrous sulphate and sodium pyruvate. For improved selectivity cephazolin in the formulation was replaced by cefoperazone as a selective agent2.
Campylobacter are Gram-negative, spirally shaped microaerophilic organisms which may be present in raw milk, untreated water, improperly handled food and undercooked meats, poultry and shellfish. Human consumption of these organisms can result in a range of clinical illnesses from transient asymptomatic colonisation to severe dysentery. The symptoms of Campylobacter enteritis include diarrhoea, stomach pain, nausea, fever, headache and muscle pain.
Use Campylobacter Blood-Free Selective Agar Base for isolation of Campylobacter species.
- Selective: due to the presence of the selective agents like cefoperazone and amphotericin B the medium is selective for Campylobacter
- Suitable for isolation of Campylobacter spp from non-clinical samples following enrichment in Exeter broth3.
- Recommended by the U.K. Ministry of Agriculture, Fisheries and Food (MAFF) as a validated method for isolation of Campylobacter from foods.4
The colonial morphology of campylobacters can be used as a guideline for identification to species level. Campylobacter jejuni strains produce grey, moist flat spreading colonies. Some strains may have a green hue or a dry appearance, with or without a metallic sheen. Campylobacter coli strains tend to be creamy-grey in colour, moist, slightly raised and often produce discrete colonies.
