Sublethal concentrations of ciprofloxacin induce bacteriocin synthesis in Escherichia coli.
Antibiotics that interfere with DNA replication, as well as cell wall synthesis, induce the SOS response. In this report, we show that ciprofloxacin induces synthesis of colicins, narrow-spectrum antibiotics frequently produced by Escherichia coli strains, in an SOS-dependent manner.
