Reoviridae. Reovirus is a member of the family Reoviridae, which includes six genera, three of which infect animals: rotavirus, orbivirus, and reovirus (7).. The classification of the member viruses of the genus Rotavirus has historically been based on both genotypic and serologic analyses and currently includes eight species.

Family: Reoviridae Chapter Version: ICTV Ninth Report; 2009 Taxonomy Release Virion properties Morphology. Virus particles of members of the family Reoviridae (collectively called reoviruses) have icosahedral symmetry but may appear spherical in shape. The protein capsid is organized as one, two or three concentric layers of capsid proteins, which surround the linear dsRNA segments of the.
Reoviridae. A reovirus is a naturally occurring oncolytic virus that usurps for its replication the activated Ras-signaling pathways of tumor cells that in most malignant gliomas are activated via upstream signaling by receptor tyrosine kinases (see Figure 21.1).

The family Reoviridae is composed of eight genera: Orthoreovirus, Orbivirus, Coltivirus, Rotavirus, Aquareovirus, Cypovirus, Phytoreovirus, and Fijivirus. Certain Orthoreovirus, Orbivirus, Coltivirus, and Rotavirus species infect humans; Phytoreovirus and Fijivirus species infect plants and insects; the cypoviruses (the cytoplasmic polyhidrosis viruses) infect insects, and aquareoviruses.
Reoviridae. The term reovirus is an acronym derived from respiratory, enteric and orphan viruses. Original isolations of these viruses were from respiratory and enteric samples but without associated clinical disease, hence the term orphan.
Classification of Reoviridae. Genome: The reoviral genome is one of the defining characteristics of the family. It has a DOUBLE-STRANDED RNA genome, which makes it unlike any other RNA virus. This genome is linear and segmented. The number of segments seen in a virus depends on the genera the particular virus is found in.
The Reoviridae genome consists of 10 to 12 segments (depending on the genus) of linear, double-stranded RNA. The complete genome is 23.7 kilobases long. The 5’ terminus of the segments have a methylated nucleotide cap. IV. Physical properties of virion.

Virus classification is the process of naming viruses and placing them into a taxonomic system. Similar to the classification systems used for cellular organisms, virus classification is the subject of ongoing debate and proposals. (by whom?) This is mainly due to the pseudo-living nature of viruses, which is to say they are non-living particles with some chemical characteristics similar to.
Essay on Classification of Viruses: A universal classification of all viruses, growing in animal, plant, bacteria, fungi etc. as host organisms, is a difficult task. An International Committee on Taxonomy of Viruses has endeavored to work out a classification and nomenclature.Classification.

Distribution.Reovirus definition is - any of a family (Reoviridae) of double-stranded RNA viruses that have a virion with icosahedral structural symmetry but may appear spherical, that have a capsid with one to three concentric protein layers, and that include many plant or animal pathogens (such as the rotaviruses and the causative agent of bluetongue).
