title: IncI2 plasmids specify sensitivity to filamentous bacteriophage IKe.
abstract: Bacterial strains carrying the derepressed incompatibility group IncI2 plasmids TP114drp-l or R721pilc were lysed by the filamentous bacteriophages IKe, I2-2, and X. Phage I2-2 was serologically related to IKe, but phage X was not. Phage IKe adsorbed to the tips of thick pili determined by the IncI2 plasmids, but not to the well-known thin I2 pili.
