- Reovirus is a RNA virus, constituting the family Reoviridae, a small group of animal and plant viruses.
- Member viruses have a wide host range, including vertebrates, invertebrates, plants, protists and fungi.
- Reovirus is a nonenveloped double-stranded RNA virus.
- This virus was initially not known to be related to any specific disease, and so was named Respiratory Enteric Orphan virus.
- They lack lipid envelopes and package their segmented genome within multi-layered capsids.
- Characteristic features of structure, preferred hosts, and chemistry are the basis for dividing reoviruses into several genera, of which Orthoreovirus, Orbivirus, Rotavirus, and Phytoreovirus are among the best known.
- The MCRV, known as Sleeping Disease, has taken a toll on wild crab in Crab Fattening and Crab polyculture (in which shrimp and wild crab are cultured in the same pond and exclusive mud crab ponds).
- The viral pathogen mainly affects the connective tissue of hepatopancreas, gills, and intestine.
