ABSTRACT

ABSTRACT

Chloramphenicol pretreatment of Escherichcia coli increases resistence to UV, X-rays and H2O2 damage. Increased ssurvival of UV-irradiated, infecting gama phages is not observed. The hypothesis that enhanced survival of chloramphenicol-pretrated cells is due to the induction of plasmid "repairons" is questioned
