title: Host cell reactivation capacity of different strains of E. coli B resistant or sensitive to ozone.
abstract: Host cell reactivation capacity for ozonated or irradiated phage was determined for different strains of E. coli either more sensitive or resistant to ozone than the wild type strain. The results suggest that the ozr gene product could be involved in the same repair pathway for ozone-induced lesions on DNA as the polA gene. The possible involvement of a specific endonuclease for these lesions is also considered.
