Taxonomy
Group: dsRNA
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.
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.
