Taxonomy
The family contains the following genera:[1]
- Cardoreovirus
- Crabreovirus
- Mimoreovirus
- Orbivirus
- Phytoreovirus
- Rotavirus
- Seadornavirus
Characteristics
Like other members of the Reovirales order, viruses of the Sedoreoviridae family are made of naked, icosahedral capsids containing 10-12 segments of linear double-stranded RNA (dsRNA). The Baltimore System of viral classification categorizes Reovirales in Group III.
Importance
Viruses classified in the Sedoreoviridae family 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
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]
