''Dicistroviridae'' is a family of viruses in the order Picornavirales. Invertebrates, including aphids, leafhoppers, flies, bees, ants, and silkworms, serve as natural hosts. There are currently 15 species in this family, divided among 2 genera. Diseases associated with this family include: DCV: increased reproductive potential. extremely pathogenic when injected with high associated mortality. CrPV: paralysis and death.〔(【引用サイトリンク】url=http://viralzone.expasy.org/all_by_species/36.html )〕〔(【引用サイトリンク】title=Virus Taxonomy: 2014 Release )〕 ==Taxonomy== Although many dicistroviruses were initially placed in the Picornaviridae, they have since been reclassified into their own family. The name (Dicistro) is derived from the characteristic dicistronic arrangement of the genome. This family is a member of the Order Picornavirales (Comoviridae, Iflavirus, Picornaviridae, Potyviridae, and Sequiviridae). Within this order, the gene order is the gene order of the nonstructural proteins Hel(helicase)-Pro(protease)-RdRp(polymerase). The Dicistroviridae can be distinguished from the members of the taxa by the location of their structural protein genes at the 3' end rather than the 5' end (as found in Iflavirus, Picornaviridae and Sequiviridae) and by having two genomic segments rather than a single one (as in the Comoviridae).
