Summary
Different strains of E. coli commonly used in genetic studies were exposed to ozone and the results described in this paper indicate that exrA and (lex), but not uvrA genes affect sensitivity to ozone. No relationship between this latter property and the capacity to repair UV-damaged infecting phage (host cell reactivation) was also found. The hypothesis is proposed that the association of ozone sensitivity and X-rays sensitivity in the same mutants may reflect common steps in the mechanism of DNA repair.
