Classification

This is a description of a vertebrate virus at the species level with data limited to classification details. If you have primary data on this virus, please submit them to ICTVdB using the online data entry systems or contact the ICTVdB management.

ICTVdB Virus Code: 00.009.0.02.001. Virus accession number: 09002001. Obsolete virus code: 09.0.2.0.001; superceded accession number: 09020001.

Name, Synonyms and Lineage

ICTV approved acronym: IBDV. Virus is the type of the genus 00.009.0.02. Avibirnavirus in the family 00.009. Birnaviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 60 nm. Capsids appear hexagonal in outline. The capsomer arrangement is clearly visible. The capsid consists of 132 capsomers. Surface projections are not present.

Capsids all have the same appearance.

Nucleic Acid

The Mr of the genome constitutes 9.7% of the virion by weight. The genome is segmented and consists of two segments of linear, double -stranded RNA. Minor species of non-genomic nucleic acid are also found in virions. The complete genome is 5924 nucleotides long. Sequence can be accessed from EBI-EMBL, or GenBank; the segment A is fully sequenced. Complete sequence is 3129 nucleotides long. Segment B is fully sequenced, complete sequence is 2795 nucleotides long and has the accession number
[M19336] (reference strain 002-73). The 5'-end of the genome has a on both segments genome-linked protein (VPg) (of 94 kD). The 3'-terminus has no poly (A) tract. The multipartite genome is found in one type of particle only.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins.

Lipids

Lipids are absent.

Transcription: Sub-genomic RNA is present in infected cells. The mRNA is a transcription of RNA-A and RNA-B.

Biological Properties

Natural Host

Virus infects during its life cycle a single type of vertebrate host.
Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Animalia.

Kingdom Animalia
Phylum Chordata.

Phylum Vertebrata Class Aves.

Host Classification Virus infects Order Galliformes; Family Phasianidae; Genus Gallus; Species gallus (chicken) (NCBITaxID 9031).

DELTA - DEscription Language for TAxonomy developed by Dr Mike Dallwitz, Toni Paine and Eric Zurcher, CSIRO Entomology, Canberra, Australia. 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.
