ICTV approved acronym: EHDV. Virus is an ICTV approved species of the genus 00.060.0.02. Orbivirus in the family 00.060. Reoviridae.

Virion Properties

Morphology

Virions consist of a capsid, a core, and a nucleoprotein complex. Virus capsid is not enveloped. Capsid/nucleocapsid is isometric with icosahedral symmetry and has a diameter of 80 nm. The capsid shells of virions are composed of two layers. Capsids appear round. The capsid surface structure does not reveal a regular pattern with distinctive features. Surface projections are often lost during preparation, or distinct spikes protruding from the 12 vertices. Inner capsids have a diameter of about 60 nm. Virus preparations contain one particle component. The core is spherical.

Only one species is recovered in preparations.

Nucleic Acid

The Mr of the genome constitutes 16% of the virion by weight (, cores of 25%). The genome is segmented and consists of ten segments of linear double-stranded RNA. The complete genome is 19200 nucleotides long. The 5'-terminal sequence has conserved regions; terminal repeats at the 5'-end are 8-34 nucleotides long; 5'-end of the genome has a methylated nucleotide cap; cap sequence type is m7G5ppp5'GmpNp. The 5'-terminus has no poly (C) tract. The 3'-terminus has conserved nucleotide sequences; of 6 nucleotides in length; in all segments and viruses of same species; sequence has conserved regions; sequence has the non-coding region is 31-116 nucleotides in length; in each gene segment. The multipartite genome is divided among different particles, each segment encapsidated separately.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 84% of the particle weight (cores of 75%).

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are absent.

Biological Properties

Natural Host

Virus infects during its life cycle arthropod and vertebrate hosts. Virus has an enzootic cycle and is transmitted from arthropod vector to competent reservoir host. Domain
Viral hosts belong to the Domain Eucarya.

Transmission and Vector Relationships

Virus is transmitted by a vector in a direct manner.
