Enrichment for detection of Campylobacter jejuni.

Gifu anaerobe-modified semisolid medium supplemented with vancomycin, polymyxin B, trimethoprim, and amphotericin B can serve as an efficient enrichment for the recovery of Campylobacter jejuni under aerobic conditions. It is superior to the direct plating method in its recovery of very small numbers of C. jejuni. Blood supplementation, agitation, and elevated temperatures are not required for this improved recovery.
