The IBR (infectious bovine rhinotracheitis) virus may spread via nerves, too.
T
We can vaccinate against papillomavirus diseases.
T (Autovaccines)
To prevent malignant catarrhal fever, live attenuated virus vaccines are used.
F (does not exist)
The Aujeszky-disease can cause nervous symptoms in sucking piglets.
T
- Ataxia
In a herd, lethality means the percent of the dead animals within the diseased ones
T
The serum ELISA test is suitable to estimate the time of infection.
T
During the parvovirus infection of dogs, the apical cells of the intestinal villi suffer a massive necrosis, thus an
osmotic diarrhea is formed
T
To prevent the Aujeszky disease in disease-free countries, extensive vaccination of the swine flocks is used
F
PCV-2 induces skin and kidney lesions in swine.
F
In the diagnostics of PCV-2 infection in swine, the qPCR test is an efficient tool.
T
The swinepox is zoonotic.
F
In the clinical appearance of swinepox, the role of predisposing factors is significant.
T
The lumpy skin disease is zoonotic
F
The canine parvovirus-2 infection can be prevented using live attenuated vaccines
T
In the vaccine containing live pathogens, the strains used are always of weakened virulence
T
In the viral infections, secondary bacterial infective agents can modify the pathological lesions
T
High maternal antibody levels always improve the efficacy of the vaccination
F
The economical loss due to Lumpy skin diseases is negligible
F
- decreased of milk production , economic loss
The PCV-2 disease can be prevented using vaccination
T
- live attenuated
The infectious laryngotracheitis virus frequently causes a permanent blindness in dogs (blue eye)
F
- fever, nasal discharge, dry cough
infectious canine hepatitis : chronic: blue eye
The myxomatosis is usually seasonal in Europe.
T
The DIVA principle can be applied in those cases too, when the animals were vaccinated with a non-delete
strain-containing vaccine
T
HUNGARIAN QUESTION = The clinical picture of cowpox is very similar to herpes mammilitis
T
Mortality means the number of dead animals compared to the total number of animals, in a herd
T
Lumpy skin disease can be spread from herd to herd with fomites
F
- sheep and goat pox
The sheep and goat pox can cause respiratory signs.
T
Parvoviral diarrhea in dogs is caused by canine parvovirus 2
T
The mucosal form is the severe one in fowl pox.
T
- malignant
The antibody levels against swine parvovirus, can be measured with ELSA test
T
In dogs, the most significant losses due to herpesvirus infection is in neonatal age animals
T
The disease-free status swine flocks to Aujeszky virus infection, can be checked with ELISA
T
IBR: the vaccinated animals can be distinguished from the non-vaccinated ones, using serology tests
T
Marek disease symptoms occur rarely because of the vaccination
T
Hemorrhagic nephritis enteritis disease of geese is caused by a polyomavirus
T
The SPF animals do not have a normal intestinal flora.
T
Poxviruses cause inclusion bodies in the cytoplasm
T
The circoviral disease of swine causes an immunosuppression
T
The PMWS appears with clinical symptoms primarily in suckling piglets
F
There are vaccines for the prevention of horse herpesvirus diseases
T
- inactivated
The Aujeszky-disease appears in young dogs with respiratory signs
F
The pathogen of contagious pustular dermatitis can infect cattle. ORF
F
- sheep, goat, human, wild goats, deers, camel, seal
The IBR virus causes a primary fibrinous pneumonia
F
- pneumonia I secondary infection
The infectious laryngotracheitis virus in acute infection of bitches causes the absorption of foetuses.
F
- no bitches
The Aujeszky-disease virus, in suckling piglets, can cause a fatal encephalitis
T
In a tolerated infection, high levels of pathogen-specific IgG can be detected, using a serology ELISA test.
T
The EDS virus may spread via germinative way.
T
The Aujeszky-disease in cats can be securely diagnosed only postmortem
T?
Wild rodents are the asymptomatic carriers of the Aujeszky-disease
F
The EDS virus causes necrotizing lesions to the ovaries in laying hens.
EDS= egg drop syndrome
