Spounavirinae is a subfamily of viruses in the family Herelleviridae . [1] [2] Bacteria serve as natural hosts. There are currently five species in this subfamily, divided among 2 genera. [2] [3]
The subfamily has two genera: [2]
Viruses in the subfamily 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. [2] [3]
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. [2] [3]
