Table of Contents

Classification

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

ICTVdB Virus Code: 00.050.1.01. Virus accession number: 050101GE. Obsolete virus code: 50.1.1.; superceded accession number: 50110000.
NCBI Taxon Identifier NCBI Taxonomy ID: 10781.

Name, Synonyms and Lineage

Virus is of the subfamily Parvovirinae; of the family 00.050. Parvoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The nucleocapsid is isometric and has a diameter of 20-26 nm. Capsids appear round. The capsid consists of 60 capsomers, each a quadrilateral 'kite-shaped' wedge. Surface projections are small, surface appears rough, and distinct spikes.

Capsids can be penetrated by stain and some appear dark in the center and only one species is recovered in preparations, or virus may occur together with a dependent virus.

Porcine parvovirus

Capsid structures, detailed structural and computational analysis are found in the Protein Data Bank (PDB) using VIPERdB, the VIrus Particle ExploreR Canine parvovirus; Feline panleukopenia virus and Porcine parvovirus.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.39-1.45 g cm-3.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear, negative-sense, single-stranded DNA in most mature virions, or of linear, negative-sense and positive-sense single-stranded DNA in up to 50% in some members. The complete genome is 5000 nucleotides long, has terminally redundant sequences and is repeated at both ends. Nucleotide sequences at the 3'-terminus are complementary to similar regions on the 5' end, or unrelated to the 5'-terminus. The 5'-terminal sequence has palindromic repeats, forming a hairpin structure; terminal repeats at the 5'-end are 200-242 nucleotides long. The 3'-terminus has conserved nucleotide sequences; of 115-116 nucleotides in length; in species of same genus; sequence has hairpin structure. Populations of mature viruses contain particles with equivalent numbers of positive and negative sense ssDNA . Upon extraction, the complementary DNA strands usually form dsDNA.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins.

Lipids

Lipids are absent.

Translation: Virions are associated with helper virus, but independent from its functions during replication.

Biological Properties

Natural Host

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

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.
