T1 bacteriophage production in Escherichia coli.

Feiner, Rose R. (Columbia University, New York, N.Y.) and Solon A. Ellison. T1 bacteriophage production in Escherichia coli. J. Bacteriol. 85:7-11. 1963.-Progeny released from complexes formed between unirradiated Escherichia coli strain Bs-1 and ultraviolet (UV)-irradiated phage T1 were equally infective for strains B and Bs-1, and were therefore not hostmodified. The capacity of Bs-1 for unirradiated or irradiated T1 is relatively insensitive to UV irradiation, as compared with that of strains B and B/r. In all three strains of E. coli, B, B/r, and Bs-1, the UV sensitivity of the capacity for phage T1 is independent of the UV sensitivity of colony-forming ability. These findings are discussed in relation to the partial genetic homology hypothesis.
