Survival responses to aerobic stress in the Campylobacter jejuni are highly influenced by preculturing conditions in either microaerobic or anaerobic environments before the stress is induced. In anaerobically precultured cells, culturability was maintained longer than that in microaerobically precultured cells under aerobic conditions, without significant concomitant damage to cellular components by aerobic stress, although the culturability finally fell below the level of detection. These results suggest a possibility that the survival of C. jejuni in natural aerobic environments is highly influenced by the environmental conditions, such as varied oxygen partial pressure, where the bacterium has resided.
