Reovirus

About Reovirus-

• 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.
