Reoviridae

Re·o·vir·i·dae

(rē'ō-vir'i-dē),
A family of double-stranded RNA viruses, some of which (Reovirus) previously were included with Echoviruses, and others (Orbivirus), with arboviruses. Virions are 60-80 nm in diameter, usually naked, and ether resistant; genomes contain double-stranded, segmented RNA (MW 10-16 × 106); capsids are of icosohedral symmetry with two layers of capsomeres. The family comprises nine genera: Orthoreovirus, Orbivirus, Rotavirus, Coltivirus, Aquareovirus, cytoplasmic polyhedrosis virus group (Cypovirus), and three plant reovirus groups (Phytoreovirus, Fijivirus, and Oryzavirus).

Reoviridae

/Reo·vi·ri·dae/ (re″o-vir´ĭ-de) the reoviruses: a family of RNA viruses with a linear double-stranded RNA genome; it includes the genera Orbivirus, Orthoreovirus,Rotavirus, and Coltivirus.

Re·o·vir·i·dae

(rē'ō-vir'i-dē)
A family of double-stranded RNA viruses, comprising six genera: Reovirus, Orbivirus, Rotavirus, cytoplasmic polyhidrosis virus group (Cypovirus), and two plant reovirus groups (Phytoreovirus, Fijivirus).

Reoviridae

a family of nonenveloped, medium-sized viruses that have a double capsid structure and a segmented double-strand RNA genome. There are three genera of importance in veterinary medicine: Orthoreovirus (previously Reovirus), Orbivirus and Rotavirus.

Reoviruses have wide host ranges and are classified into 11 genera: Orthorevirus, Obrivirus, Rotavirus, Coltivirus, Seadornavirus, Aquareovirus, Cypovirus, Idnoreovirus, Fijivirus, Phytoreovirus, and Oryzavirus in the family Reoviridae by the International Committee for the Taxonomy of Viruses (2000).
Such viruses include Ebola and Marburg viruses, Nipah and Hendra viruses, severe acute respiratory syndrome-like coronavirus, rabies and other lyssaviruses, togaviruses, flaviviruses, bunyaviruses, and members of the family Reoviridae (11-13).
In this study, a serologic survey was conducted for 4 groups of viruses, 2 from the family Paramyxoviridae and 2 from the genus Orthoreovirus, family Reoviridae.
Banna virus (BAV), the prototype species of genus Seadornavirus within the family Reoviridae, has a genome composed of 12 segments of double-stranded RNA (1).
Epizootic hemorrhagic disease virus (EHDV) is a member of the genus Orbivirus, family Reoviridae, and is closely related to bluetongue virus (BTV).
Rotaviruses are members of the Reoviridae family (2) and are classified into 7 groups (A-G) on the basis of distinct antigenic and genetic properties (3).
The disease occurs worldwide and is caused by bluetongue virus (BTV), which belongs to the genus Orbivirus within the family Reoviridae.
