Sedoreovirinae (sedo = smooth) is a subfamily of the Reoviridae family of viruses.[1] Viruses in this subfamily are distinguished by the absence of a turreted protein on the inner capsid to produce a smooth surface.[2]

Characteristics

Like other members of the Reoviridae family, viruses of the Sedoreovirinae subfamily are made of naked, icosahedral capsids containing 10-12 segments of linear double-stranded RNA (dsRNA). The Baltimore System of viral classification categorizes Reoviridae in Group III.

Importance

Viruses classified in the Sedoreovirinae subfamily infect a wide range of plants and animals, including some that can infect humans. There is not only the potential of a few of these viruses to cause human disease, but also to reduce the supply of crops and livestock.

Viruses

Genus Cardoreovirus

Eriocheir sinensis reovirus was isolated out of a Chinese mitten crab (Eriocheir sinensis). No currently known associated disease.[3]

Genus Mimoreovirus

Microsomonas pusilla reovirus was isolated from the marine protist Micromonas pusilla[4]

Genus Orbivirus

Arboviruses containing dsRNA are placed in this genus. Some Orbivirus infect livestock with high rates of morbidity and mortality.[5] Includes: Bluetongue virus, African horse sickness virus, Epizootic hemorrhagic disease virus, among others.

Genus Phytoreovirus

Known phytoreoviruses are plant pathogens causing dwarfism and the formation of tumors.[6] Included: Rice dwarf virus, Rice gall dwarf virus and Wound tumor virus.

Genus Rotavirus

Rotavirus A-E cause infantile gastroenteritis in humans and farm animals.[7]

Genus Seadornavirus

Many known Seadornaviruses cause encephalitis in humans. Included: Banna virus, Kadipiro virus and Liao ning virus.[8]
