Par·vo·vir·i·dae

(par'vō-vir'i-dē),
A family of small viruses containing single-stranded DNA. Virions are 18-26 nm in diameter, are not enveloped, and are ether resistant. Capsids are of cubic symmetry, with 32 capsomeres. Replication and assembly occur in the nucleus of infected cells. Three genera in the subfamily Parvovirinae are recognized: Parvovirus, Erythrovirus, and Dependovirus, which includes the adeno-associated virus. A second subfamily, Densovirinae, has three additional genera, all of which infect arthropods.

/Par·vo·vi·ri·dae/ (pahr″vo-vir´ĭ-de) the parvoviruses: a family of DNA viruses with a linear single-stranded DNA genome, including the genera Parvovirus and Dependovirus.

Par·vo·vir·i·dae

(pahr'vō-vir'i-dē)
A family of small viruses containing single-stranded DNA. Three genera are recognized: Parvovirus, Densovirus, and Dependovirus, which includes the adeno-associated satellite virus.

Parvoviridae

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.

Transmission routes of human parvovirus 4 (PARV4), a recently discovered member of the Parvoviridae family (1), are not fully understood; studies have suggested that PARV4 is transmitted predominantly through the parenteral route (2,3).
A new member of family Parvoviridae, human parvovirus 4 (PARV4), was identified in plasma of an injection drug user (IDU) with unexplained fatigue, headaches, fever, night sweats, nausea, and diarrhea (1).
Genetic characterization of the complete genome sequence of the virus showed a distant relationship to existing genera within the family Parvoviridae, although viruses showing 61%-63% sequence similarity to PARV4 have recently been described in pigs and cows (2), together likely meriting the designation of a new genus within the family.
In 2005, parvovirus 4 (PARV4), a new putative member of the family Parvoviridae, was identified in the plasma of a patient in North America who had an acute virus infection (1).
To the Editor: Human parvovirus 4 (PARV4) is a recently identified virus, distantly related to already known members of the family Parvoviridae that affect humans and animals.
