PARVOVIRUS Flashcards
There is no neutralizing epitope of parvoviruses.
F
The reproduction of the parvovirus is continuous in the dividing cells.
T
Parvoviruses are good antigens
T
Bocaviruses may cause mild respiratory or enteric diseases in newborn animals.
T
Parvoviruses can be cultured in homologous, young dividing cell cultures.
T
The resistance of Parvovirus is high, in the environment they remain infectious for
several months.
T
Parvoviruses multiplicate only in rapidly dividing cells.
T
SMEDI is caused by goose circovirus.
F
SMEDI is caused by porcine circovirus
F
If 75-day-old swine foetuses are infected with parvovirus myoclonia congenital is a
clinical sign
T
If 75-day-old swine foetuses are infected with parvovirus respiratory clinical signs can
be seen in the piglets
F
The embryo can be infected with porcine parvovirus 1.
T
Parvovirus rarely causes SMEDI in endemic farms.
T
Swine parvovirus can cause foetal damages only if the infection takes place during the
pregnancy.
T
Swine parvovirus occurs worldwide, most herds are seropositive.
T
If 100-day-old swine foetuses are infected with parvovirus, respiratory clinical signs can be seen.
F
If 100-day-old swine foetuses are infected with parvovirus, weak piglets can be seen
T
If 100-day-old swine foetuses are infected with parvovirus, myoclonia congenital is a
clinical sign
T
If 100-day-old swine fetuses are infected with parvovirus, dermatitis is a clinical sign
F
SMEDI is caused by porcine parvovirus
T
If 15 day old swine foetuses are infected with parvovirus myoclonia congenital is a
clinical sign
F
If 100-day-old swine fetuses are infected with parvovirus, respiratory clinical signs can
be seen
F
If 75 day old swine foetuses are infected with parvovirus abortion can be seen
F
If 15 day old swine foetuses are infected with parvovirus mummification can be seen
F
The porcine parvovirus 1 causes renal disorders in adults
F
Porcine parvovirus (PPV 1) vaccinations start at or after 6 months of age
T
PPV 1 is transmitted through the fecal-oral route
T
PPV 1 is endemic in most pig herds
T
Porcine parvovirus 4 is usually involved in reproductive disorders
T
Swine parvovirus is shed in the faeces for some weeks after contracting the infection
T
The maternal immunity against porcine parvovirus lats for a very long time
T
PCR is used for the detection of antibodies against porcine parvovirus 1
F
Porcine SMEDI can only be induced by parvoviruses
F
PPV-1 induces diarrhoea in suckling piglets.
F
Neurological disorders are frequent in Porcine parvovirus infections.
F
The primary site of Porcine parvovirus (PPV-1) replication is in the small intestine.
T
Swine parvovirus usually causes foetal damages in first pregnant gilts.
T
Swine parvovirus maternal antibodies can exist up to 6 to 12 months of age.
F
The maternal immunity against porcine parvovirus lasts for very long time.
T
Porcine parvovirus can cause neurological signs in sows
F
Porcine parvovirus frequently causes diarrhoea in piglets.
F
For prevention of Porcine parvovirus caused fetal damages, live vaccines are available.
T
Piglets of sows seroconverted by PPV-1 are maternally protected for months.
T
Porcine parvoviruses are genetically uniform.
F
Porcine parvovirus (PPV-1) infection of seronegative pregnant animals can damage the
foetus
T
PPV-1 vaccination must be started at 4-6 weeks of age
F
Vaccination against canine parvovirus 2 is independent from maternal antibodies
F
Vaccination against canine parvovirus 2 depends on maternal antibodies
T
The parvovirus enteritis of dogs is caused by canine parvovirus 1
F
The parvovirus enteritis of dogs is caused by canine parvovirus 2
T
The parvoviral enteritis of dogs is type 3 hypersensitivity
F
