Cryspovirus is a genus of viruses, in the family Partitiviridae. Protists serve as natural hosts. There is currently only one species in this genus: the type species Cryptosporidium parvum virus 1.[1][2]
Taxonomy
Group: dsRNA
Order: Unassigned
- Family: Partitiviridae
- Genus: Cryspovirus
- Cryptosporidium parvum virus 1
Structure
Viruses in Cryspovirus are non-enveloped, with icosahedral geometries, and T=1 symmetry. The diameter is around 30-35 nm. Genomes are linear and segmented, around 2.1kb in length. The genome codes for 2 proteins.[1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |
|---|---|---|---|---|---|
| Cryspovirus | Icosahedral | T=1 | Non-Enveloped | Linear | Segmented |
Life Cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. Protists serve as the natural host.[1]
