The lytic activity of plague phage II, serovar 3, with respect to 1,800 bacterial strains has been studied: 760 Yersinia pestis strains, 262 Y. pseudotuberculosis strains, 252 Y. enterocolitica strains, 166 Escherichia coli strains, 90 Shigella strains and 270 strains of other species.

The bacteriophage designated RD2 has been isolated from the sewage in Rostov-on-Don city and studied. The morphology of bacteriophage particles and the biological properties of the bacteriophage make it related to the plague bacteriophage isolated by D'Errel. The molecular masses of the compared bacteriophages are almost identical being 26.

Four Y. enterocolitica strains (10166, 10373, 2119, 5513) have been studied for the presence of the enzymatic systems of modification-restriction (M-R). As revealed with the use of cross titration, strains 10166 and 10373 contain M-R systems, supposedly of type II.

Isolation of the same phage type from different bacterial species permits to regard them as "polyhostal" ones.
