Abstrakt: ABSTRACTInhibition of DNA replication in an Escherichia coli dnaB-22mutant failed to block quinolone-mediated lethality. Inhibition of protein synthesis by chloramphenicol inhibited nalidixic acid lethality and, to a lesser extent, ciprofloxacin lethality in both dnaB-22and wild-type cells. Thus, major features of quinolone-mediated lethality do not depend on ongoing replication.
