Fuselloviridae
Fuselloviridae is a family of archaeal viruses that infects sulfolobus species. The family contains four genera: Alphafusellovirus, Betafusellovirus, Gammafusellovirus, and Deltafusellovirus.
Taxonomy[edit | edit source]
The family Fuselloviridae is divided into four genera:
- Alphafusellovirus
- Betafusellovirus
- Gammafusellovirus
- Deltafusellovirus
Each genus contains several species of viruses.
Structure[edit | edit source]
Fuselloviridae viruses are non-enveloped, with rod-shaped geometries. The diameter is around 55-60 nm, with a length of 90-100 nm. The viruses are composed of a lipid membrane, enclosing a circular, double-stranded DNA genome.
Life Cycle[edit | edit source]
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. The virus exits the host cell by lysis, and holin/endolysin/spanin proteins are involved. Sulfolobus species serve as the natural host.
Pathology[edit | edit source]
The pathology of Fuselloviridae is not well understood due to the extremophilic nature of their hosts. However, they are not known to cause disease in humans.
