Infulenza viruses attach to the host cells via the neuroaminidase protein.
F
Infulenza viruses can be propagated in embryonated eggs.
T
Infulenza in horses is a chronic disease without general, febrile signs.
F
Swine infulenza can affect pigs at any age
T
Wild birds never develop signs of avian infulenza.
F
In humans, vaccination against infulenza virus provides life-long protection.
F
Bovine parainfulenza virus 3 causes only rhinitis, not pneumonia; therefore it is easy to differentiate from Bovine respiratory syncytial virus infection.
F
Only ruminants are susceptible to the Rinderpest virus.
F
Because rinderpest virus was eradicated from the Earth, no further animal testing is necessary.
F
Attenuated canine distemper virus vaccine may have adverse effect.
T
Preventive vaccination can mitigate mortality and economic losses of velogenic Newcastle disease.
T
Newcastle disease usually cannot be differentiated from avian infulenza on tha basis of clinical signs.
T
Nipah virus was first detected in central America (in Nicaragua, Panama and Honduras).
F
Domestic swine may act as amplifying host of Nipah virus.
T
Antihistamine ay have advantageous effect in the treatment of cattle suffering Bovine respiratory syncytial virus induced pneumonia.
T
Yolk immunity prevents chicken from Avian metapneumonia infection.
F
Avian metapneumoviruses may cause reduced egg production.
T
Transmissible gastroenteritis epizootics may cause high mortality in new-born piglets.
T
Enzootic transmissible gastroenteritis is usually seen in piglets around weaning
T
Cats are reservoir hosts of the porcine epidemic diarrhoea virus.
F
Bovine coronaviruses are usually infecting the enterocytes in the crypts of Liberkühn.
F
Canine enteric coronaviruses are usually causing diarrhoea in 2-6 months old dogs.
T
Canine respiratory coronavirus frequently cause severe, haemorrhagic pneumonia.
F
The Feline enteric coronavirus is antigenically different from the feline infectious peritonitis virus.
F
The Porcine reproductive and respiratory syndrome virus (PRRSV) frequently causes encephalitis in piglets.
F
Aerogenic infection is the main way of spreading of ephemeral fever virus.
F
Ephemeral fever is a zoonotic disease.
F
Rabies has been eradicated from Europe.
F
Rabies viruses within the same phylogroup provide cross protection
T
Rabies virus us shed only in the saliva.
F
Alteration of behavior is an important clinical sign of rabies.
T
All ruminants are susceptible to ovine pulmonay adenomatosis virus.
F
Ovine pulmonary adenomatosis virus is transmitted by ticks.
F
Chronic persistant infection is common in the case of ovine pulmonary adenomatosis.
T
Clinical signs of ovine pulmonary adenomatosis are extremely severe in lambs under 6 months of age.
F
Milk is the main way of transmission of caprine arthritis encephalitis virus.
T
Caprine arthritis encephalitis virus causes encephalitis mainly above 1 year of age.
F
Using generation shift caprine arthritis encephalitis can be eradicated from the herd. Caprine arhritis encephalitis is a zoonosis.
F
