Parvovirus, commonly called parvo, is a
genus of the Parvoviridae family of DNA viruses. Parvoviruses are some of the
smallest viruses found in nature (hence the name, from Latin parvus meaning
small). Like all members of the parvoviridae family, they infect only mammals.
Parvoviruses can cause disease in some animals. For example, Canine
parvovirus is a particularly deadly disease among young puppies, causing
gastrointestinal tract damage and dehydration as well as a cardiac syndrome in
very young pups. Mouse parvovirus 1, however, causes no symptoms but can
contaminate immunology experiments in biological research laboratories. The most
accurate diagnosis of parvovirus is by ELISA. Dogs and
cats can be
vaccinated against parvovirus.
Many types of mammalian
species have a strain of parvovirus associated with them. A parvovirus tends to
be specific about the taxon of animal it will infect. That is, a canine
parvovirus will affect dogs, wolves, and foxes, but will not infect cats or
humans.
Parvovirus B19, which causes fifth disease in humans, is a member of the
Erythrovirus genus of Parvoviridae rather than Parvovirus.
