ICTV approved acronym: CPV-5. Virus is an ICTV approved species of the genus 00.060.0.06. Cypovirus in the family 00.060. Reoviridae.

Virion Properties

Morphology

Virions consist of a capsid, a core, and a nucleoprotein complex. Virus may be sequestered within inclusion bodies that are not occluded and typically contain one nucleocapsid, or occluded by protein bodies. Virus capsid is not enveloped, round with icosahedral symmetry. The capsid is isometric. The capsid shells of virions are composed of a single inner capsid layer. Capsids appear round. The capsid surface structure reveals a regular pattern with distinctive features. The capsomer arrangement is clearly visible. Surface projections are distinct hollow spikes protruding from the 12 vertices. Inner capsids have a diameter of 55-69 nm. Virus preparations contain one particle component. The core is spherical with a diameter of 35 nm.

Only one species is recovered in preparations.

Nucleic Acid

The genome is monomeric; segmented and consists of ten segments of linear double-stranded RNA. The complete genome is 20500-24000 nucleotides long (size distribution of the genome segments cited at beginning of description). The 5'-terminal sequence has conserved regions; terminal repeats at the 5'-end are 5 nucleotides long (5'-AGUUU..). The 3'-terminus has conserved nucleotide sequences; in viruses of same species; sequence has 7 nucleotides in length (3'-CGUUGAG..., in all RNA species. The multipartite genome is found in one type of particle only. Each virion contains a single copy of the genome; a full length copy.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses by Dr Cornelia Büchen-Osmond is written in DELTA. The virus descriptions in ICTVdB are coded by, or using data from experts in the field of virology or members ICTV. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations are automatically generated and formatted for display on the Web from the descriptions in DELTA-format. The description has been generated automatically from DELTA files.
