Classification

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

ICTVdB Virus Code: 00.016.0.02.001. Virus accession number: 16002001. Obsolete virus code: 16.0.1.0.001; superceded accession number: 16010001.
NCBI Taxon Identifier NCBI Taxonomy ID: 12618.

Name, Synonyms and Lineage

The taxon has the accepted ICTV name.

Alternative name: chicken infectious anemia virus. Synonym(s): chicken anemia agent. ICTV approved acronym: CAV. Virus is the type of the genus 00.016.0.02. Gyrovirus in the family 00.016. Circoviridae.

Virion Properties

Morphology

Virions consist of a capsid. During their life cycle, virions have an extracellular phase. Virus capsid is not enveloped. Virions are not tailed. Capsid/nucleocapsid is round and exhibits icosahedral symmetry (T=13). The capsid is isometric and has a diameter of 23.5 nm. Capsids appear round. The capsid surface structure reveals a regular pattern with distinctive features; is maintained using conventional electron microscopy. The capsid consists of 32 capsomers (that are hollow morphological subunits).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.33-1.37 g cm-3. There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 91 S20w.

Nucleic Acid

The genome is monomeric; not segmented and contains a single molecule of circular, negative-sense, single-stranded DNA ; that forms a covalently closed circle. The complete genome is 2298-2319 nucleotides long.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of numerous proteins located in the capsid.

Structural Proteins: Capsid protein capsid. Capsid protein has a molecular mass of 22510 Da.

Lipids

Lipids are not reported.

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.
