zone solution, 4.0mL of sterile trimethoprim lactate solution, 4.0mL of
sterile vancomycin solution, and 4.0mL of sterile cycloheximide solu-
tion. Mix thoroughly. Aseptically distribute into sterile screw-capped
tubes or bottles. Close caps tightly to reduce O2 absorption. Use within
2 weeks.
Use: For the selective isolation and cultivation of Campylobacter spe-
cies.
