PETRIDISH 90MM CAMPYLOB BLOODFREE CCDA 10pc

One of several media formulations available for the selective isolation of Campylobacter spp., primarily C.jejuni and C.coli, which are the leading cause of intestinal disease in the UK. Campylobacter spp. can cause mild to severe diarrhoea, usually self-limiting, but some specific serotypes can cause acute post-infectious conditions affecting the peripheral nervous system, such as Guillain-Barré syndrome.

Campylobacter blood-free selective medium (CCDA) was first described by Bolton. This medium was formulated to replace blood with a combination of charcoal, ferrous sulphate and sodium pyruvate. To improve selectivity, Cefoperazone also replaced Cephazolin used in the original formulation. Bolton recommended incubating inoculated plates at 37°C to improve the isolation rate, but incubation at 41.5°C is recommended for the isolation of the common thermophilic species (C.jejuni & C.coli). Yeast and mould contaminations can be suppressed by the addition of Amphotericin B.

Campylobacter blood-free selective medium (CCDA) is recommended for food testing. Campylobacter blood-free selective medium with the addition of yeast extract and Cefoperazone is used in the isolation of Campylobacter species from food and swabs according to the FDA / BAM method. The product meets the requirements of ISO 10272-1: 2006.
