Fuselloviridae is a family of viruses . Sulfolobus shibatae, sulfolobus solfataricus, and sulfolobus islandicus serve as natural hosts. There are currently nine species in this family, divided among 2 genera. [1][2] The Fuselloviridae are ubiquitous in high-temperature (≥70°C), acidic (pH ≤4) hot springs around the world. They are one of the few viruses to possess a lipid membrane and a protective inner capsid in the form of a core.
Taxonomy
Group: dsDNA
- Family: Fuselloviridae
Structure
Viruses in Fuselloviridae are enveloped, with lemon-shaped geometries. The diameter is around 60 nm, with a length of 100 nm. Genomes are circular, around 17.3kb in length. [1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Alphafusellovirus | Lemon-shaped | Enveloped | Circular | Monopartite | |
| Betafusellovirus | Lemon-shaped | Enveloped | Circular | 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. Sulfolobus shibatae, sulfolobus solfataricus, and sulfolobus islandicus serve as the natural host. [1]
| Genus | Host Details | Tissue Tropism | Entry Details | Release Details | Replication Site | Assembly Site | Transmission |

| Alphafusellovirus | Archea: thermolophilic | None | Injection | Budding | Cytoplasm | Cytoplasm | Passive diffusion |
| Betafusellovirus | Archea: thermolophilic | None | Injection | Budding | Cytoplasm | Cytoplasm | Passive diffusion |
