Giardiavirus is a genus of viruses, in the family Totiviridae. Protozoa serve as natural hosts. There is only one species in this genus: Giardia lamblia virus.[1][2]
Structure
[edit]Viruses in Giardiavirus are non-enveloped, with icosahedral geometries, and T=2 symmetry. The diameter is around 36 nm. Genomes are linear, around 6277kb in length. The genome has 2 open reading frames.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Giardiavirus | Icosahedral | T=2 | Non-enveloped | Linear | Monopartite |
Life cycle
[edit]Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediates endocytosis. Replication follows the double-stranded RNA virus replication model. Double-stranded rna virus transcription is the method of transcription. Translation takes place by -1 ribosomal frameshifting, and viral initiation. Protozoa serve as the natural host.[1]
| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
|---|---|---|---|---|---|---|---|
| Giardiavirus | Protozoa | None | Cell receptor endocytosis | Exocytosis | Cytoplasm | Cytoplasm | Passive diffusion |
Taxonomy
[edit]The genus Giardiavirus has one species:[2]
- Giardia lamblia virus
