Cardoreovirus is a genus of viruses, in the family Reoviridae, in the subfamily Sedoreovirinae. Crabs serve as natural hosts. There is currently only one species in this genus: the type species Eriocheir sinensis reovirus. Diseases associated with this genus include: trembling disease.[1][2]

Structure
Viruses in Cardoreovirus are non-enveloped, with icosahedral geometries, and T=13, T=2 symmetry. The diameter is around 55 nm. Genomes are linear and segmented.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Cardoreovirus | Icosahedral | T=13, T=2 | Non-enveloped | Linear | Segmented |
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. The virus exits the host cell by monopartite non-tubule guided viral movement. Crabs serve as the natural host. Transmission routes are passive diffusion.[1]
