Parvoviridae Infections: Virus infections caused by the PARVOVIRIDAE.Parvoviridae: A family of very small DNA viruses containing a single molecule of single-stranded DNA and consisting of two subfamilies: PARVOVIRINAE and DENSOVIRINAE. They infect both vertebrates and invertebrates.Parvovirus: A genus of the family PARVOVIRIDAE, subfamily PARVOVIRINAE, infecting a variety of vertebrates including humans. Parvoviruses are responsible for a number of important diseases but also can be non-pathogenic in certain hosts. The type species is MINUTE VIRUS OF MICE.Densovirus: A genus of PARVOVIRIDAE, subfamily DENSOVIRINAE, comprising helper-independent viruses containing only two species. Junonia coenia densovirus is the type species.Parvovirinae: A subfamily of DNA vertebrate viruses, in the family PARVOVIRIDAE. There are three genera: PARVOVIRUS; ERYTHROVIRUS; and DEPENDOVIRUS.Erythrovirus: A genus of the family PARVOVIRIDAE, subfamily PARVOVIRINAE, and containing the type species PARVOVIRUS B19, HUMAN.Bocavirus: A genus in the subfamily PARVOVIRINAE comprising three species: Bovine parvovirus, Canine minute virus, and HUMAN BOCAVIRUS.Circoviridae: A family of very small viruses containing circular, single-stranded DNA and possessing no envelope. The modes of transmission are not known.Genome, Viral: The complete genetic complement contained in a DNA or RNA molecule in a virus.Phylogeny: The relationships of groups of organisms as reflected by their genetic makeup.Sequence Analysis, DNA: A multistage process that includes cloning, physical mapping, subcloning, determination of the DNA SEQUENCE, and information analysis.DNA, Viral: Deoxyribonucleic acid that makes up the genetic material of viruses.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
