Which medium is specifically associated with selective recovery of Campylobacter from GI specimens?

Explanation:
Campylobacter is fastidious and grows best under low-oxygen, higher-temperature conditions. A medium that provides a microaerophilic atmosphere and incubates at about 42°C specifically favors Campylobacter while inhibiting many competing GI bacteria, and the longer 48-hour incubation gives this slower-growing organism time to form colonies. That combination—Campylobacter-adapted atmosphere, elevated temperature, and extended incubation—is what makes CAMP microaerophilic (N2) 42C 48h the best choice for selective recovery from GI specimens. The other media operate under aerobic conditions, lower temperatures, or are designed for other enteric pathogens, so they don’t provide the same selective environment for Campylobacter.
