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.
Group: dsDNA
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.
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.
