Turriviridae Explained

Turriviridae is a family of viruses; it contains only one genus, Alphaturrivirus. The archaea Sulfolobus solfataricus serve as natural hosts. There are two species in the genus Alphaturrivirus.^{[1] [2]}

Taxonomy

The genus contains the following species:

• Sulfolobus turreted icosahedral virus 1

Structure

Viruses in Turriviridae have icosahedral geometries, and T=31 symmetry. The diameter is around 74 nm. Genomes are circular.^[1]

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. Sulfolobus solfataricus serves as the natural host. Transmission routes are passive diffusion.^[1]
