Spounalikevirus is a genus of viruses in the order Caudovirales, in the family Myoviridae, in the subfamily Spounavirinae. Bacteria serve as natural hosts. There is currently only one species in this genus: the type species Bacillus phage SPO1.[1][2][3]

- Bacillus phage SPO1
Structure
Viruses in Spounalikevirus are non-enveloped, with head-tail geometries, and T=16 symmetry. The diameter is around 108 nm, with a length of 140 nm. Genomes are linear, around 145kb in length. The genome codes for 200 proteins.[1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Spounalikevirus | 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]

Taxonomic history
- Bacillus phage SP8 was assigned to the family Myoviridae in 1995.
- Bacillus phage SPO1 was assigned to the genus SPO1-like phages in 1996 as type species.
- Myoviridae were assigned to the order Caudovirales in 1998
- SPO1-like phages were renamed SPO1-like viruses in 1999
- Bacillus phage SP8 was merged into Bacillus phage SPO1 in 1999 (as type species) of SPO1-like viruses.
- SPO1-like viruses were assigned to the sub-family Spounavirinae (of Caudovirales) in 2011.
- SPO1-like viruses were renamed Spounalikevirus in 2012
