Abstract

The conditions required to kill with nalidixic acid, ciprofloxacin, norfloxacin or ofloxacin were determined in nutrient broth and in phosphate-buffered saline. They were found to be similar to the conditions required for these 4-quinolones to kill Bacterial RNA synthesis and bacterial cell division were essential for the bactericidal activity of nalidixic acid but all three fluoroquinolones were bactericidal against non-dividing However, as with , bacterial RNA synthesis was essential for the bactericidal activity of norfloxacin though this was not required to kill with ciprofloxacin or ofloxacin.
