Spounavirinae is a subfamily of viruses in the order Caudovirales, in the family Myoviridae. Bacteria serve as natural hosts. There are currently eight species in this subfamily, divided among 2 genera.[1][2]
Taxonomy
Group: dsDNA
- Family: Myoviridae
- Sub-Family: Spounavirinae
- Genus: Unassigned
Structure
Viruses in Spounavirinae are non-enveloped, with icosahedral and Head-tail geometries, and T=16 symmetry. The diameter is around 84-94 nm, with a length of 140-219 in length, contractile with globular structures at its tip, has 6 long terminal fibers, 6 short spikes and a double base platenm. Genomes are circular, around 130-160kb in length. The genome codes for 190 to 230 proteins.[1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Spounalikevirus | Head-Tail | T=16 | Non-Enveloped | Linear | Monopartite |
| Twortlikevirus | Head-Tail | T=16 | Non-Enveloped | Linear | 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 |
|---|---|---|---|---|---|---|---|
| Spounalikevirus | Bacteria | None | Injection | Lysis | Cytoplasm | Cytoplasm | Passive diffusion |
| Twortlikevirus | Bacteria | None | Injection | Lysis | Cytoplasm | Cytoplasm | Passive diffusion |
