Peduovirus (also known as P2-like phages and P2-like viruses) is a genus of viruses in the family Peduoviridae of the class Caudoviricetes . [1] Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are 30 recognised species in this genus. [1]
The following species are recognized in the 2023 ICTV classification: [1]
Peduoviruses are nonenveloped, with a head and tail. The icosahedral head is approximately 60 nm in diameter and a dextral symmetry (T=7), composed of 72 capsomers. The tail is around 135 nm long, 18 nm wide, has 6 short, kinked tail fibers. The tail is enclosed in a sheath, which loosens and slides around the tail core upon contraction. [5]

| Peduovirus | Head-Tail | T=7 dextro | Non-enveloped | Linear | Monopartite |
Nine of the viruses' genomes have been fully sequenced and are available on NCBI's website (though Salmonella phage Fels-2 is currently listed as unclassified). They range between 30k and 39k nucleotides, with 40 to 51 proteins. Complete genomes, as well as several additional "unclassified" virus genomes, are available at [6]
Viral replication is cytoplasmic. The virus attaches to the host cell using its tail fibers, and ejects the viral DNA into the host cytoplasm via contraction of its tail sheath. DNA-templated transcription is the method of transcription. Once the viral genes have been replicated, the procapsid is assembled and packed. The tail is then assembled and the mature virions are released via lysis and holin/endolysin/spanin proteins. [5]

According to ICTV's 1996 report, the genus P2likevirus was first accepted under the name P2-like phages in the family Myoviridae , unassigned to a sub-family. [7] The genus name was changed to P2-like viruses in the ICTV 7th Report in 1999. It was moved into the subfamily Peduovirinae upon its inception in 2010-11. The following year (2012), the genus was renamed to P2likevirus. These reports are available through ICTV here: 1996, 1999, 2010, 2012. [8] The genus was later renamed to Peduovirus. In 2021, subfamily Peduovirinae was elevated to family Peduoviridae. [7]
Myoviridae was a family of bacteriophages in the order Caudovirales. The family Myoviridae and order Caudovirales have now been abolished, with the term myovirus now used to refer to the morphology of viruses in this former family. Bacteria and archaea serve as natural hosts. There were 625 species in this family, assigned to eight subfamilies and 217 genera.
Enterobacteria phage P4 is a temperate bacteriophage strain of species Escherichia virus P2 within genus Peduovirus, subfamily Peduovirinae, family Myoviridae. It is a satellite virus, requiring P2-related helper phage to grow lytically.
Hpunavirus is a genus of viruses in the family Peduoviridae. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are two species in this genus.
Twortvirus is a genus of viruses in the order Caudovirales, in the family Herelleviridae, in the subfamily Twortvirinae. Bacteria serve as natural hosts. There is only one species in this genus: Staphylococcus virus Twort.
Schizotequatrovirus is a unassigned genus of viruses in the unassigned family Straboviridae, in the class Caudoviricetes,. Bacteria serve as natural hosts. There are three species in this genus.
Tequatrovirus is a genus of viruses in subfamily Tevenvirinae of family Straboviridae. Gram-negative bacteria serve as the natural host, with transmission achieved through passive diffusion. There are 84 species in this genus.
Felixounavirus is a genus of viruses in the order Caudovirales, in the family Myoviridae. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are currently 16 species in this genus, including the type species Salmonella virus FelixO1.
Bixzunavirus is a genus of viruses in the order Caudovirales, in the family Myoviridae. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are eight species in this genus.
Muvirus is a genus of viruses in the order Caudovirales, in the family Myoviridae. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are two species in this genus.

Teseptimavirus is a genus of viruses in the order Caudovirales, in the family Autographiviridae, in the subfamily Studiervirinae. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are currently 17 species in this genus, including the type species Escherichia virus T7.
Salasvirus is a genus of viruses in the order Caudovirales, in the family Salasmaviridae, in the subfamily Picovirinae. Bacteria serve as natural hosts. There are four species in this genus.
Lederbergvirus is a genus of viruses in the order Caudovirales, in the family Podoviridae. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are six species in this genus.
