Parvoviridae

(virology) A family of deoxyribonucleic acid (DNA)-containing animal viruses characterized by an icosahedral virion containing three or four structural proteins and a single-stranded DNA genome; includes the Dependovirus, Parvovirus, and Densovirus genera.

One of the major deoxyribonucleic acid virus families to which the B₁₉ virus belongs. Viruses in this family have a single-stranded linear molecular structure with icosahedral symmetry.

A family of small viruses containing single-stranded DNA; replication and assembly occur in the nucleus of infected cells.

A family of small (20 nm diameter) icosahedral single-stranded DNA viruses that are nonenveloped. There are three genera of veterinary importance: Parvovirus, which includes feline panleukopenia virus, mink enteritis virus, canine, bovine and porcine parvoviruses and Aleutian mink disease virus; Densovirus, which occur in insects; Erythrovirus which infect primates; and Dependovirus, which are defective, requiring adenoviruses to complete their replication, and are nonpathogenic (called also adeno-associated viruses). Autonomously replicating parvoviruses replicate only during S phase of the cell cycle, i.e. they attack dividing cells.

The Parvoviridae family includes the smallest known viruses, and some of the most environmentally resistant. They were discovered during the 1960s and affect vertebrates and insects. Parvoviridae have a genome consisting of single-stranded DNA and an icosahedral capsid.

Parvovirus B19 was the first human parvovirus to be discovered and is best known for causing a childhood exanthem called "fifth disease" (erythema infectiosum), although it is also associated with other diseases including arthritis.

Parvovirus RA-1 had originally also been associated with rheumatoid arthritis, but this is now thought to have been an error due to laboratory contamination.

The following genera are included here:
