Abstract:
A solid or semi-solid culture medium, designated Campy-Cefex, for the isolation of Campylobacter species. The culture medium includes: (a) a nutrient medium with an energy source effective to support growth of Campylobacter; (b) agar; (c) blood; (d) a first selective agent selected from cycloheximide, its salts, or mixtures thereof; and (e) a second selective agent selected from cefoperazone, its salts, or mires thereof. In use, the sample to be analyzed is inoculated onto the Campy-Cefex culture medium, and subsequently incubated for a sufficient time and under conditions effective to promote growth of Campylobacter. Following incubation, the culture medium may then be examined for the presence of any colonies of Campylobacter.
