    Bacteriophage PRD1 is a member of the Tectiviridae family and is closely related to the other lipid-containing phages PR3, PR4, PR5, and L17.It is a plasmid-dependent phage that has been shown to infect a variety of gram-negative hosts, including Escherichia coli, with the requirement that hosts contain incompatibility group plasmids P, W, or N. Bacteriophages that replicate through the lytic life cycle are called lytic bacteriophages, and are so named because they lyse the host bacterium as a normal part of their life cycle.
