Listeria phage P100 is a virus of the family Myoviridae, genus Twortlikevirus.[1][2]
As a member of the group I of the Baltimore classification, Listeria phage P100 is a dsDNA viruses. All the Myoviridae family members share a nonenveloped morphology consisting of a head and a tail separated by a neck. Its genome is linear. The propagation of the virions includes the attaching to a host cell (a bacterium, as Listeria phage P100 is a bacteriophage) and the injection of the double stranded DNA; the host transcribes and translates it to manufacture new particles. To replicate its genetic content requires host cell DNA polymerases and, hence, the process is highly dependent on the cell cycle.[3]
Its genome contains 131,384 base pairs that encode 174 open reading frames and 18 tRNAs. Listeria phage P100 has been proposed as food additive to control Listeria monocytogenes.[4]
