>The effects of various chemical mutugens on the radiosensitivity of Nocardia corallina were investigated. The application of the unpaired defect theory of Tobias and the ploidy stute in N. corallina were also studied. Nocardia corallina was used as a diploid cell and Micrococcus aureus and Escherichia coli were used as haploid cells for comparative purposes. Chemicals used included nitrogen mustard, sodium azide, copper sulfate, caffeine, ascorbic acid, mercuric chloride, manganous chloride, and hydrogen peroxide. Data are tabulated on the effects of pretreatment with the chemicals on response to ultraviolet and x radiations. Results are also included from a study of the effects of ultraviolet radiation on the cytology snd colony development of Nocardia corallina. The effects of pigment on radiosensitivity and factors involved in the development of radiation-resistant strains are discussed. (For preceding period see ORO-283.) (C.H.)
