herpes 2 hardcore Flashcards
In swine the most serious CS of Aujeszys disease are usually seen in piglets
T
Severe illness in piglets
The Aujeszys disease in cats is usually a mild respiratory disease with quick recovery
FDogs: Fever Itching Salivation Paralysis DeathCats: Fever Itching (might be absent) Salivation Anisocoria Convulsions Death
The natural reservoir hosts of the Aujeszys disease virus are rodents
F
The pig is the only species able to survive a productive infection in the wild
he symptoms of Aujeszys disease in ruminants is similar to rabies
T?
Central nervous signs of the Aujeszky’s disease are rarely seen in adult swine
T
Asymptomatic or constipation dyspnoea coughing
Swine are immunized against the Aujeszky’s disease virus usually with gE negative marker vaccines
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
Tsevere illness =febrile + cns → death or even before cns in 1-2 daysno respiratory
Aujeszky`s disease causes pneumonia in susceptible piglets
F
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 necrotic foci in the liver of the foetus
T
Fever and serous nasal discharge are early signs of acute equine rhinopneumonitis
T
Pregnant mares abort usually in the acute phase of equine rhinopneumonitis
F
After EHV1 infection pregnant mares abort in the acute febrile stage
F
Equid herpesvirus 1 may cause subclinical infection in horses
Tadults are often asymptomatic
Equine herpesvirus-1 contains cross-reactive proteins against disease caused by EHV-4
T
Vaccination containing Equine herpesvirus-1 also provides protection against EHV-4
T
Equine herpesvirus-1 primarily causes respiratory symptoms in horses.
FReproductive mainly
Equine herpesvirus-1 primarily causes abortion
T
Mares infected with Equine herpesvirus-1 have a febrile state, then abort.
T
It is enough to vaccinate mares 2 times against Equine herpesvirus-2
Fwe dot generally vaccinate animals because:only foals are diseasedlow pathogenicity anwanw we would need multiple vaccinations due to low antigenicity
Equid herpesvirus 3 can cause lesions on the genital mucosa without abortion
Tno abortion since is local infection with no viremia
