Further Studies of Mycobacteriophage 33D (Warsaw) for Differentiation of BCG From M. Bovis and M. Tubeculosis

Tubercle. 1979 Mar;60(1):55-8. doi: 10.1016/0041-3879(79)90057-6.


Mycobacteriophage 33D (Warsaw) was used to differentiate Bacille Calmette-Guerin (BCG) strains from M. bovis and M. tuberculosis. Known strains as well as clinical strains of BCG were used in the study. Single plaque isolations and adsorption studies demonstrated that phage 33D (Warsaw) did not adsorb to BCG cultures.
