Myohalovirus (synonym: PhiH-like viruses, Phihlikevirus) is a genus of viruses in the order Caudovirales , in the family Myoviridae . Bacteria and archaea serve as natural hosts. There are three species in this genus. [1] [2]
The following three species are assigned to the genus: [2]
Myohaloviruses are nonenveloped, with a head and tail. The head is icosahedral with a diameter of about 64 nm. The tail is around 170 nm long, 18 nm wide, has short terminal fibers, and is contractile. [1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Myohalovirus | Head-Tail | Non-enveloped | Linear | Monopartite |
Genomes are circular, around 59kb in length. The genome codes for 100 proteins. [1]
Viral replication is cytoplasmic. The virus attaches to the host cell using its terminal 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. Bacteria and archaea serve as the natural host. Transmission routes are passive diffusion. [1]

According to the ICTV's 1997 report, the genus PhiH-like viruses was first accepted as a new genus in the family Myoviridae, at the same time as its type species. This proposal is available here. The following year (1998), the genus was added to the newly created order Caudovirales. In 1999, a name change is reported, but no change actually occurred. In 2012, the name was changed to Phihlikevirus. This proposal is available here. [2] The genus was later renamed to Myohalovirus.
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.
Uetakevirus is a genus of viruses in the order Caudovirales, in the family Podoviridae. Bacteria serve as natural hosts. There are three species in this genus. These phages are temperate and infect Salmonella and Escherichia coli.
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.
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.
Hapunavirus is a genus of viruses in the class Caudoviricetes, not assigned to a subfamily. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are two species in this genus. Hapunavirus was classified in the family Myoviridae.
Bixzunavirus is a genus of viruses in the subfamily Ceeclamvirinae. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are eight species in this genus. Bixzunavirus were previously classified under the order Caudovirales, in the family Myoviridae.
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.
Pbunavirus is a genus of viruses in the order Caudovirales, in the family Myoviridae. Bacteria serve as natural hosts. There are 27 species in this genus.
