Cryspovirus
Cryspovirus is a genus of viruses, in the family Partitiviridae.[1] Protists serve as natural hosts. There is currently only one species in this genus: the type species Cryptosporidium parvum virus 1.[2][3]

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.[2][3]
| 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.[2][3]

gollark: I see.
gollark: At least Lua doesn't have the !!FUN!! C(++) memory management stuff going on.
gollark: Gotos are *more* prone to that than some other things.
gollark: Well, gotos often just lead to convoluted messy control flow.
gollark: Well, goto bad.
