Bocavirus
A genus in the subfamily PARVOVIRINAE comprising three species: Bovine parvovirus, Canine minute virus, and HUMAN BOCAVIRUS.
Human bocavirus
A member of the family PARVOVIRIDAE, subfamily PARVOVIRINAE, originally isolated from human nasopharyngeal aspirates in patients with respiratory disease.
Parvovirinae
A subfamily of DNA vertebrate viruses, in the family PARVOVIRIDAE. There are three genera: PARVOVIRUS; ERYTHROVIRUS; and DEPENDOVIRUS.
Respiratory Tract Infections
Nasopharynx
The top portion of the pharynx situated posterior to the nose and superior to the SOFT PALATE. The nasopharynx is the posterior extension of the nasal cavities and has a respiratory function.
DNA, Viral
Deoxyribonucleic acid that makes up the genetic material of viruses.
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.
Gastroenteritis
INFLAMMATION of any segment of the GASTROINTESTINAL TRACT from ESOPHAGUS to RECTUM. Causes of gastroenteritis are many including genetic, infection, HYPERSENSITIVITY, drug effects, and CANCER.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Viruses
Metapneumovirus
A genus of the subfamily PNEUMOVIRINAE, containing two members: Turkey rhinotracheitis virus and a human Metapneumovirus. Virions lack HEMAGGLUTININ and NEURAMINIDASE.

Parvovirus B19, Human
Virus Diseases
A general term for diseases produced by viruses.
