Cultures from fresh isolates of Nocardia corallina displayed a wide variation in dose-survivor response to both x radiation and ultraviolet light. Cultures more sensitive to irradition than the parent strain were found to be composed of a high percentage of bacillary cells, which were probably the cause of the sensitivity. Cultures with extreme resistance to irradiation were found, but these revented on subculture or standing to become similar in response to the parent culture. This transient radiation resistance is thought to be due to a recessive allele and is presumably lost through heterocaryon formation. Isolates of three bacterial cultures did not display the extreme variation in radiation response found in N. corallina. (auth)
