Altered phage P1 attachment to strains of Escherichia coli carrying the plasmid ColV,I-K94.

Abstract

Phages P1vir and P1cmclrf100 failed to form plaques on or multiply in Escherichia coli strains carrying the ColV,I-K94 plasmid; with P1cmclr100, the effect occurred both with phage from the lytic cycle and with that induced from a lysogen. The effect was on attachment, these P1 phages attaching poorly to ColV,I-K94+ strains. This receptor defect appeared to… (More)
