Pasteurella pestis Bacteriophage H and Escherichia coli Bacteriophage φII Are Nearly Identical

Abstract

Electron microscopy examination of φII-H deoxyribonucleic acid heteroduplexes, together with polyacrylamide gel electrophoretic analyses of phage ribonucleic acid species and proteins labeled in φII or H-infected cells, demonstrates that Pasteurella pestis phage H is nearly identical to coliphage φII.
