Campylobacter Karmali Agar Base (Dehydrated)

Isolate Campylobacter jejuni and Campylobacter coli using Thermo Scientific™ Oxoid™ Campylobacter Karmali Agar Base (Dehydrated) when used with Modified Karmali Selective Supplement (SR0205) or Campylobacter Selective Supplement (Karmali) (SR0167). Campylobacter Karmali Agar Base is based on the formulation described by Karmali et al.¹ and is recommended for the isolation of Campylobacter jejuni and Campylobacter coli from clinical specimens.

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 colonization to severe dysentery. The symptoms of Campylobacter enteritis include diarrhoea, stomach pain, nausea, fever, headache and muscle pain.

Use Campylobacter Karmali Agar Base for isolation of Campylobacter species.

• Selective: due to the presence of the selective agents like vancomycin and amphotericin B the medium is selective for Campylobacter
• Easy-to-read: Campylobacter jejuni strains produce grey, moist, flat spreading colonies after 42-hour incubation at 42°C.

Campylobacter Karmali Agar Base is a modification of the original Campylobacter Blood Free medium. Campylobacter Blood Free medium contains sodium pyruvate in the agar base. Campylobacter Medium (Karmali) incorporates this ingredient into the selective supplement. The original medium also contains sodium desoxycholate for the inhibition of Gram-positive organisms, whereas with Campylobacter Medium (Karmali) suppression of Gram-positives is achieved by the inclusion of vancomycin.
