LYSOGENY IN ENTEROPATHOGENIC ESCHERICHIA COLI: II. CHARACTERIZATION OF E. COLI BACTERIOPHAGE D-1

Abstract

One of 20 strains of Escherichia coli O111:B4 was found to be lysogenic for a phage which showed activity on several O26:B6 strains. High titers of this phage were obtainable only by UV induction. Normal propagation procedures failed to provide a desirable yield of phage. The calculated burst size of this phage was approximately 36 particles per cell. Other characteristics of the phage, designated D-1 by the authors, are given. Its potentiality as a possible transducing agent was also investigated. Some evidence is offered for the suspected site of attachment on the host cell.
