Mechanism of Action of Nalidixic Acid on Escherichia coli V. Possible Mutagenic Effect

Abstract
Cook, Thomas M. , (Sterling-Winthrop Research Institute, Rensselaer, N.Y.), William A. Goss, and William H. Deitz . Mechanism of action of nalidixic acid on Escherichia coli . V. Possible mutagenic effect. J. Bacteriol. 91: 780–783. 1966.—With a streptomycin-dependent organism, Escherichia coli ATCC 11143, it has been shown that exposure to nalidixic acid, under conditions permitting some bactericidal action, results in an increased number of streptomycin-independent bacteria among the survivors. This effect is evident only with proliferating cultures, and is related to the concentration of nalidixic acid and the duration of exposure.
