Punavirus is a genus of viruses in the order Caudovirales, in the family Myoviridae. Bacteria serve as natural hosts. There are four species in this genus.[1][2]
Taxonomy
The following four species are assigned to the genus:[2]
- Aeromonas virus 43
- Escherichia virus P1
- Escherichia virus RCS47
- Salmonella virus SJ46
Structure
Viruses in Punavirus are non-enveloped, with icosahedral and head-tail geometries. The diameter is around 85 nm. Genomes are circular, around 100kb in length. The genome codes for 100 proteins.[1]
Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
Punavirus | Head-Tail | | Non-enveloped | Circular | Monopartite |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Bacteria serve as the natural host. Transmission routes are passive diffusion.[1]
Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
