Abstract

Summary

DNA repair-proficient and -deficient strains of were used to examine host cell reactivation, Weigle reactivation and photoreactivation of u.v.-irradiated cholera bacteriophages. U.v. light-induced DNA damage in phages of different morphological and serological groups could be efficiently photoreactivated. Host cell reactivation of irradiated phages of different groups was different on the same indicator host. Phage ø149 was the most sensitive, and ø138 the most resistant to u.v. irradiation. While ø138 showed appreciable host cell reactivation, this was minimal for ø149. Attempts to demonstrate Weigle reactivation of u.v.-irradiated cholera phages were not successful, although u.v.-induced filamentation of host cells was observed.
