Seadornavirus ''Seadornavirus'' is a genus of viruses, in the order ''Reovirales'', in the family ''Sedoreoviridae''. Human, cattle, pig, and mosquitoes serve as natural hosts. There are three species in this genus: Banna virus (BAV), Kadipiro virus, and Li ...

Characteristics

Like other members of the ''

'' 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.
