Sedoreoviridae


Sedoreoviridae is a family of the Reovirales order of viruses. Viruses in this family are distinguished by the absence of a turreted protein on the inner capsid to produce a smooth surface.

Taxonomy

The family contains the following genera:
  • 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. 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''

was isolated out of a Chinese mitten crab. No currently known associated disease.

Genus ''Mimoreovirus''

was isolated from the marine protist Micromonas pusilla.

Genus ''Orbivirus''

Some Orbivirus infect livestock with high rates of morbidity and mortality.
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.
Included: Rice dwarf virus, Rice gall dwarf virus, and Wound tumor virus.

Genus ''Rotavirus''

A-E cause infantile gastroenteritis in humans and farm animals.

Genus ''Seadornavirus''

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