herpes 2 Flashcards
The Aujeszy’s disease virus is stenoxen
F
Wild boars are not susceptible to Aujeszy’s disease virus
F
Abortion of sows can be a sign of Aujeszys disease
T
Pregnant Sows: Abortion SMEDI like
Pregnant sows may abort in Aujeszky’s disease
T
In swine the most serious CS of Aujeszys disease are usually seen in piglets
T
Severe illness in piglets
Dogs should be vaccinated against Aujeszys disease
F
Carnivores are the reservoir hosts of the Aujeszky’s disease virus
F
The Aujeszys disease in cats is usually a mild respiratory disease with quick recovery
F
Dogs: Fever Itching Salivation Paralysis Death
Cats: Fever Itching (might be absent) Salivation Anisocoria Convulsions Death
The signs of Aujeszys disease in dogs are similar to rabies
T
The natural reservoir hosts of the Aujeszys disease virus are rodents
F
The Aujeszy disease causes fatal pneumonia in Ruminants and Carnivores
F
The Aujeszy disease is zoonosis
F
he symptoms of Aujeszys disease in ruminants is similar to rabies
T?
The Aujeszy disease virus may infect several mammalian hosts
T
Aujeszys diseases can be latently carried by pigs in the nervous system
T
Central nervous signs of the Aujeszky’s disease are rarely seen in adult swine
T
Asymptomatic or constipation dyspnoea coughing
Convalescent swine are life-long carriers and potential shedders of Aujeszky’s disease virus
T
Swine are immunized against the Aujeszky’s disease virus usually with gE negative marker vaccines
T
Rats are the reservoir hosts of the Aujeszky’s disease
F
The Suid herpesvirus 1 frequently causes encephalitis in humans
F
Liquid manure may play a role in the transmission of Suid herpesvirus 1 from swine to cattle
T
Discriminative ELISA tests may differentiate between vaccinated swine wild type Suid- herpesvirus infected ones
T
In adult swine the most frequent manifestation of Aujeszky’s disease is encephalitis
F
Aujeszky’s disease virus infection in adult pigs is frequently subclinical
T
Pigs infected with wild type Aujeszky’s disease virus can be differentiated from vaccinated ones by serological tests (i.e ELISA).
T
Cattle should be vaccinated against Malignant Catarrhal Fever
F
Aujeszky ́s disease can occur in pigs and cats
T
Aujeszky ́s disease in pigs causes viraemia
T
Aujeszky ́s disease in cats spreads along the nerves
T
direct access to the brain no viremia and virus shedding
spreading with the nerves
Aujeszky ́s disease can cause respiratory signs in adult pigs
T
asymptomatic or constipation coughing dyspnoea
Aujeszky ́s disease causes fever in day old piglets
T
severe illness =febrile + cns → death or even before cns in 1-2 days
no respiratory
Aujeszky`s disease causes pneumonia in susceptible piglets
F
Aujeszky`s disease doesn’t cause clinical signs in susceptible piglets
F
Aujeszky`s disease causes pruritus in susceptible piglets
F
less itching or rarely
Aujeszky`s disease causes 20-30% mortality in susceptible piglets
F
100%
Older pigs are more frequently affected by Aujeszky ́
F
Equine rhinopneumonitis virus is transmitted by arthropods
F
bovine herpes mammilitis by arthropods from teat to teat
For immunisation against equine rhinopneumonitis virus mostly marker vaccines are used.
F
inactivated modified
Equine rhinopneumonitis virus can cause abortion several weeks after acute infection
T
first reps then reproductive
abortion at 5th month of gestation
Equine rhinopneumonitis virus causes cytoplasmic inclusion bodies in the foetal hepatocytes
F
herpes = intranuclear inclusion bodies
Equid herpesvirus 4 more frequently causes encephalitis than Equid herpesvirus 1
F
1 cns + repro mainly +resp
4 resp mainly + repro
Horses should be vaccinated against equine rhinopneumonitis virus at least every 6 months
T
repetitive vaccinations weak antigenicity
Equine rhinopneumonitis virus causes necrotic foci in the liver of the foetus
T
Fever and serous nasal discharge are early signs of acute equine rhinopneumonitis
T
Equine rhinopneumonitis virus can cause purulent metritis
F
Only equine herpesvirus 4 can cause abortion
F
Pregnant mares abort usually in the acute phase of equine rhinopneumonitis
F
After EHV1 infection pregnant mares abort in the acute febrile stage
F
Immunisation against equine rhinopneumonitis virus provides life long protection
F
Equine rhinopneumonitis virus is present only in North America
F
The equid herpesvirus 1 may cause abortion storms in studs
T
Pregnant mares abort usually several weeks after equid herpesvirus 1 infection
T
Vaccinated horses cannot get infected with Equid herpesvirus 1
F
they can but will not have CS
Equid herpesvirus 1 associated abortions are always sporadic
F
Abortion storms in 40-60% of mares
