Title: THE X-RAY INDUCTION OF LYTIC UNITS IN ESCHERICHIA COLI B

Abstract

Bacteria of the strain E. coli B irradiated with small doses of x radiation (52 to 60 kv) release a transmissible lytic principle which acts on the homologous strain of E. coli B. The action of the lytic principle may be exhibited in the first or in later passages. The optimal dose is 30 r. It was demonstrated experimentally that the strain of E. coli used in these experiments is not lysogenic. In the electron microscope bacteriolysis was found, with the occurrence of regular globules and occasionally of larger particles measuring 60 to 70 m mu . The different conditions for successful induction were studied, but the lysis percentage could not be raised above 50%. The incidence of the phenomenon is not regular and is evidently chiefly dependent on the physiological state of the bacteria. (auth)
