When 40 Campylobacter jejuni isolates from human clinical cases, raw chicken and water were tested, 29 (72·5%) could be adapted to grow on nutrient agar under aerobic conditions. Once adapted, these isolates could grow on repeated aerobic subculture. An aerobically‐grown Camp. jejuni isolate survived almost as well as the same isolate grown microaerophilically in sterile chicken mince at 5 °C, and survival of a cocktail of Camp. jejuni isolates under both atmospheres was comparable at 25 °C. However, at 37 °C, the decline in numbers of the aerobically‐grown cells was greater. Survival of cells on chicken nuggets was poorer than in chicken mince. In filter‐sterilized stream water incubated aerobically at 5 °C, survival of inocula grown under different atmospheres was again similar, but slightly better with the microaerophilically‐grown cells. Adaptation to aerobic growth was not found to enhance survival under aerobic conditions.
