The vesicular stomatitis causes a clinical disease only in swine and ruminants.

After a viraemia, the rabies virus spreads centripetally to the tissues of the central nervous
system.

hyperplasia.
T
During the latent infection due to alpha herpesviruses, the specific antibodies can be
continuously measured with ELISA.
F
The IBR can be diagnosed well because of the simultaneous appearance of the respiratory and
genital symptoms.
F
The malignant catarrhal fever can emerge with mild clinical symptoms, too.
T
The J-subtype leukosis virus is typically more virulent, and the incubation time of the disease is
usually shorter than in the other subtypes.
T
During the distemper infection, even with a high level of specific antibodies, the CNS signs may
occur.
T
The bluetongue vaccines confer a type-specific protection.
T
There are no vaccines available for the prevention of the contagious caprine pleuropneumonia.
F
The proprietary, within-species cycling Leptospira of swine is the L. pomona.
T
The European wild boar population is free from the Aujeszky virus.
F
Against the horse encephalosis virus-caused human disease, vaccines are available in the USA.
F
The EDS virus spreads via the germinative route.
T
The HNEG can cause up to 100% mortalitv in dav-old animals
T
Against the Rubarth disease, the maternal antibodies can protect for up to 2 to 3 months.
T
In older breeding animals, M. hyopneumoniae can cause an agalactia and keratitis.
F
In chickens, the chronic fowl cholera mav cause the connective tissue induration of wattles
T
The zoonotic disease caused by C. jejuni is typically a non-occupational disease.
T
With the slide agglutination test, either the antigens or the antibodies can be tested
T
The virus isolation can be substituted with PCR and sequencing in all cases.
F
The Parvovirus-enteritis of weaned piglets is prevented with the vaccination of the sows with an
inactivated virus vaccine
F
For the investigation of the prions’ protein structure, the western blot test can be used
T
The MRSA frequently causes septicaemia in Humans
F?
Between the horse encephalitis virus types, there is no cross-protection.
F
The very virulent Marek virus strains cause the neural form of the disease in non-vaccinated 3-
to 6- week old chickens
F
The bovine papular stomatitis frequently occurs together with a BVD infection.
T
For the serotyping of Salmonellas, the ELISA test is used.
F AGGLUTINATION
The different serotypes and biotypes of A. pleuropneumoniae can have different virulence
properties.
T
The pathogens of the Q-fever multiplicate in the faeces-contaminated soil.
F
The Marek-virus is used as a vector of Live vaccines
T
The genital campylobacteriosis of cattle can be diagnosed with a selective culture.
T
Dogs can carry B. abortus without a clinical disease.
T
in the epidemiology of EDS, the germinative infection has a low importance.
F
In chickens, the fowl typhoid causes an exponential death curve.
F ITS A DOUBLE MORTALITY CURVE
The C. perfringens beta toxin inhibits trypsin????
F
The infectious bursitis infection in layers flocks producing eggs, can cause a strong
Immunosuppression and decreased eggs production.
F
The ELISA test can be used for the detection of either the antigen or the antibodies.
