Lomovskayavirus
Lomovskayavirus is a genus of viruses in the family Colingsworthviridae. Bacteria serve as natural hosts. There are three species in this genus.
Taxonomy
The following species are recognized:Lomovskayavirus BT1Lomovskayavirus C31
- ''Lomovskayavirus shawty''
Structure
Lomovskayaviruses are nonenveloped, with a head and tail. The head is about 53 nm in diameter, consisting of 72 capsomers. The tail is long and flexible, at about 100 nm long, 5 nm wide, has a 15 nm wide baseplate and four tail fibers ended by terminal knobs.
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
| Lomovskayavirus | Head-Tail | T=7 | Non-enveloped | Linear | Monopartite |
Genome
The species have been fully sequenced. They have about 41-42k nucleotides, with 53 and 55 proteins.
Life cycle
Viral replication is cytoplasmic. The virus attaches to the host cell's adhesion receptors using its terminal fibers, and ejects the viral DNA into the host cytoplasm via . Replication follows the replicative transposition model. 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 serve as the natural host. Transmission routes are passive diffusion.

History
According to ICTV, the genus Phic3unalikevirus was first accepted under the name PhiC31-like viruses in, assigned to family Siphoviridae in order Caudovirales. In, the genus was renamed to Phic3unalikevirus. The genus was later renamed to Lomovskayavirus.
