In 1942 the greatest threat to allied shipping was the mighty German battleship, Tirpitz. Her vast size meant that the only dock on the Atlantic seaboard that could accommodate her was at St Nazaire.**So Operation Chariot was
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.
