Bactericidal activity of enoxacin and lomefloxacin against Escherichia coli KL16.
Enoxacin and lomefloxacin were found to display a biphasic response when their bactericidal activities were investigated against Escherichia coli KL16 in nutrient broth. Although enoxacin required bacterial protein and RNA synthesis to exert bactericidal activity, it was able to kill non-dividing bacteria. On the other hand, the protein synthesis inhibitor chloramphenicol and the RNA synthesis inhibitor rifampicin did not abolish enoxacin's killing activity against Escherichia coli KL16 in nutrient broth. Lomefloxacin was also shown to be active against non-dividing Escherichia coli KL16.
