Enrichment medium for isolation of Campylobacter jejuni-Campylobacter coli.

A broth enrichment medium for the improvement of isolation of Campylobacter jejuni-Campylobacter coli from stool samples and other specimens is presented. Of 1,228 samples examined in parallel, positive results were obtained from 81 by direct inoculation of selective media and from 112 after enrichment. Thus, an increase of 27.7% in the isolation rate was obtained by using the enrichment medium. The same medium without antibiotics allows the preservation of isolates of C. jejuni-C. coli for at least 2 months at 4 degrees C.
