Cryspovirus

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. Group: dsRNA 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. 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.
