rabies hardcore Flashcards
In the case of silent rabies rabid dogs cannot bark
F
Furious rabies = change of behaviour
There is a high level of cross protection between phylogroups of rabies viruses
F
Between members of the same phylogroup3 phylogroups exists
Humans can be infected with European bat lyssaviruses in case of direct contact
T
Puppies have to be vaccinated against rabies at the age of 6 weeks
F3 months
Rabies virus can infect humans; however, humans are not very susceptible
T
Bats infected with European bat lyssaviruses frequently attack animals
T
The incubation time of rabies is generally 24-72 hours; however, exceptions can occur
F2-8 weeks
Rabies virus can only be transmitted with bite
Fper os aerosol contact with saliva or neural tissues shedding in milk and urine
Dogs have to be observed for 14 days if they have bitten humans
T
Herbivorous animals bitten by foxes can be emergency slaughtered
T
Rabies virus appears in the saliva 2-3 days after the onset of the clinical signs
Fshedding even before CS
Lethality of rabies in humans is high
T
99% lethal
The resistance of rabies virus is low; it cannot survive in the environment for a long time
T
Rabies can be diagnosed by detection of antibodies in paired sera
F
Antibodies against rabies detected with ELISA confirm the diagnosis of rabies
Findirect detection for vaccination controldirect detection confirms the diagnosis
Haemorrhages of the serous membranes are typical postmortem lesions of rabies
F
Post exposition vaccine against rabies can be given to ruminants bitten by foxes
T
Rabies virus does not penetrate the blood vessels
T
In rabies we find purulent encephalitis in negri-bodies
F Not purulent
With immunofluorescence test we can diagnose rabies
T
Fox rabies: we can use live vaccines
T
Humans can be infected by Rabies during organ transplants
Thappened in Germany and USA
Always the furious form of rabies can be seen in dogs
Ffurious or silent
There is no haematogenic spreading of the rabies virus
TNo viraemia
Cattle bitten by a rabid animal can be vaccinated after exposition
Tvaccinated or emerg slaughtered
Rabies virus cannot be cultured
Fmouse brain
Detection of Negri bodies is more sensitive than immunofluorescence test, in the case of rabies
FIF 99% sensitivitynegri bodies can be caused by other stuff as well
Virus isolation is the most widely used way of diagnosis of rabies
T
Rabid animals have to be vaccinated immediately
Fextermination not vaccination
In cats furious form of rabies is typical
T
In dogs both furious and silent form of rabies can occur
TCats + sus= Furiouseq + Ca = Both
Rabies spread through venereal
F
Rabies virus can only be found in the nervous system
Fsaliva milk urine
