Abstract
HYPERBARIC oxygen is known to be mutagenic towards Escherichia coli1–3. But, can oxygen be mutagenic at tensions physiological to man? We have studied this question using oxygen-sensitive mutants of the histidine auxotroph strain TA100 of Salmonella typhimurium constructed by Ames and his coworkers as part of a test system for carcinogens4. We find that oxygen tensions physiological to higher animals are mutagenic towards these organisms.
