A derivative of MU0001 (R) has been isolated which has been cured of an inducible prophage. This isolate, its parent strain and a relysogenized derivative of the cured strain have been compared with respect to their ultraviolet inducibility, production of plaque-forming units, bacteriophage immunity and milk coagulation properties. The bacteriophage (.MU1) harboured by strain MU0001 as a prophage has been characterized by isopycnic density gradient centrifugation, electron microscopy and sodium dodecyl sulphate gel electrophoresis. Antiserum raised against this bacteriophage was used to demonstrate true lysogeny in both the original strain and the relysogenized strain.
