title: [The effect of plasmids on the resistance of E. coli to phages].
abstract: The introduction of the ColV, I-K94 or R124 plasmid into Escherichia coli K12 resulted in resistance to certain phages. Derivatives of E. coli carrying the plasmid R124 and ColV, I-K94 were resistance to the phages T4, Mel comparing with the plasmid-free parent and the plasmid ColV, I-K94 conferred resistance to the phage Tull*. It suggested that an envelope change caused by the plasmids might be responsible for the resistance because most of the phages fell to absorb to the plasmid-bearing E. coli cells.
