Abstract:

Thirteen strains of plague bacteriophage, isolated from various objects and in various places were studied. All the phages were passaged five times on the No 319 virulent strain of the plague microbe, which subsequently was used as the strain indicator. Rabbits were immunized for obtaining the antiphage serum. The serological properties of the phages were studied in the cross neutralization reactions with homologous and heterologous antiphage sera. The morphology of negative colonies was also studied by utilizing the method of agar layers. All the strains of plague bacteriophage studied formed transparent, large negative colonies, with a normal circular form, with a diameter of 3.6--4 mm.
