Bacteriophages or phage are viruses that invade bacterial cells and, in the case of lytic phages, disrupt bacterial metabolism and cause the bacterium to lyse [destruct].Phage Therapy is the therapeutic use of lytic bacteriophages to treat pathogenic bacterial infections.Bacterial Host Specificity.electing new phages (e.g., against phage-resistant bacteria) is a relatively rapid process that can frequently be accomplished in days or weeks. Developing a new antibiotic (e.g., against antibiotic-resistant bacteria) is a time-consuming process and may take several years (16, 51).
Lambda phage is a non-contractile tailed phage, meaning during an infection event it cannot 'force' its DNA through a bacterial cell membrane. It must instead use an existing pathway to invade the host cell, having evolved the tip of its tail to interact with a specific pore to allow entry of its DNA to the hosts. Soon, the phage switches to a rolling circle replication similar to that used by phage M13. 2  The DNA is nicked and the 3â end serves as a primer. 3  Note that this does not release single copies of the phage genome but rather one long molecule with many copies of the genome: a concatemer.
