totiviridae การใช้

• Members of the " Cystoviridae " appear to be most closely related to the " Reoviridae ", but also share homology with the " Totiviridae ".
• This analysis also suggests that the dsRNA viruses are not closely related to each other but instead belong to four additional classes Birnaviridae, Cystoviridae, Partitiviridae, and Reoviridae  and one additional order ( Totiviridae ) of one of the classes of positive ssRNA viruses in the same subphylum as the positive-strand RNA viruses.
