Giardiavirus
Giardiavirus is a genus of viruses, in the family Giardiaviridae. Protozoa serve as natural hosts. There is only one species in this genus: Giardiavirus ichi.
Structure
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.| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
| Giardiavirus | Icosahedral | T=2 | Non-enveloped | Linear | Monopartite |
Life cycle
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.| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
