Media for Campylobacter jejuni and other campylobacters

Despite their recent elaboration and the many variations in antibiotic combinations designed to attain selectivity, highly selective liquid and solid culture media for Campylobacter jejuni have proved satisfactory provided they are incubated at about 42°C and in a microaerophilic atmosphere such as a candle jar. Two reservations apply: (i) cephalothin should not be used when C. fetus is to be isolated as well as C. jejuni; and (ii) typical colonies obtained on selective isolation media should always be checked for failure to grow on blood agar slants in air
