Transduction mechanisms of bacteriophage ε15II. Isolation of a bacteriophage related to ε15

Abstract

SUMMARYA bacteriophage was isolated from a strain ofSalmonella manilla. This phage, υ15, was found to have adsorption and conversion properties similar to phage ε15. The two phages show similar transduction efficiencies but phage υ15lysogenizes more efficiently. Phage υ15is not subject to repression by ε15type prophage. The densities of the two phages are indistinguishable.Phage υ15can ‘cure’ ε15type prophages and recombination is possible between genomes of the two phages. It seems probable that they are heteroimmune representatives of a single bacteriophage family.
