Table of Contents

Classification

This is a description of a vertebrate virus at the genus level.

ICTVdB Virus Code: 00.060.0.04. Virus accession number: 060004GE. Obsolete virus code: 60.0.4.; superceded accession number: 60040000.
NCBI Taxon Identifier NCBI Taxonomy ID: 10911.

Name, Synonyms and Lineage

Virus is of the family 00.060. Reoviridae.

Virion Properties

Morphology

Virions consist of a capsid, a core, and a nucleoprotein complex. Virus capsid is not enveloped. Virions are not enveloped although they are often associated with membranes in crude extracts. Capsid/nucleocapsid is round and exhibits icosahedral symmetry. The isometric capsid has a diameter of 80 nm. The capsid shells of virions are composed of two layers. Capsids appear round. The capsid surface structure reveals a regular pattern with distinctive features (that appears smooth). Virus preparations contain one particle component. The core is spherical.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.38 g cm-3.

Nucleic Acid

The genome is segmented and consists of twelve segments of linear double-stranded RNA. The complete genome is 25000-27000 nucleotides long. The multipartite genome is divided among different particles, each segment encapsidated separately. Each virion contains a single copy of the genome; a full length copy.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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.

Domain Eucarya
Kingdom Animalia.

Kingdom Animalia
Phylum Chordata.

Phylum Vertebrata
Subphylum Vertebrata; Class Mammalia.

Class Mammalia Order Primates;
Family Hominidae.
Virus infects Homo sapiens (human).

Transmission and Vector Relationships

Virus is transmitted by a vector in a direct manner.

Taxonomic Proposals and Changes

Isolate S6-14-03 from a hare collected in California in 1976 shows some one-way cross-reaction in serum neutralization tests with Eyach virus, but is clearly distinguishable and has been reported as a distinct serotype. Serological variants of Eyach virus (AR 577 and AR 578) have also been reported. Recently, several Indonesian (JKT6423, JKT6969, JKT7041, JKT7075) and Chinese (HN59, HN131, HN191, HN295) virus isolates have been made which may include serologically distinct coltiviruses.
