T2r+ bacteriophage grown in its host, Escherichia coli B, in broth medium in the presence of radioactive inorganic phosphorus was labelled with the isotope. Purified suspensions of this virus had specific activities up to 50,000 c.p.m. per μgm. P. T

A study of the physiological effects of T2 ghosts, prepared by the method of Anderson, has been made. It was found that 75% of the ghosts can be adsorbed to host cells as measured with S35. Of these, only 10 to 35% are killers. The remainder, althoug

Infection of E. coli with P32 labelled T2r+ bacteriophage resulted in the con version of a part of the isotope to a form soluble in 5% trichloroacetic acid. This acid soluble phosphorus was used as a measure of the breakdown of the virus. When the ph
