shedding even before CS

indirect detection for vaccination control
direct detection confirms the diagnosis
Rabies virus is spreading alone the nerves in the host

Rabies can be diagnosed only by using PCR

Post exposition vaccine against rabies can be given to ruminants bitten by foxes
T
Rabies virus does not penetrate the blood vessels
F
Rabies: one of the important symptoms is the change of behaviour
T
Rabies: one important symptom is paralysis
T
In rabies we find purulent encephalitis in negri-bodies
F
Not purulent
With immunofluorescence test we can diagnose rabies
T
We can diagnose rabies by antibody detection test
F
When an animal which is infected with rabies virus attacks another dog, it should be vaccinated immediately
F
Rabies is a uniform virus
F
many phylogroups and serotypes
Rabies is a resistant virus
F
Warm blooded animals can be infected with rabies
T
Rabies can be transmitted only by saliva
F
Fox rabies: we can use live vaccines
T
Since 2002 rabies is eradicated from Hungary
F
Humans can be infected by Rabies bite
T
Humans can be infected by Rabies during organ transplants
T
happened in Germany and USA
Rabies virus is spreading in the infected animals peri-neural

T
The incubation of rabies is generally less than one week
F
The rabies virus is a uniform virus without serotypes, genotypes, subtypes etc
F
High amount of rabies virus is shed in the saliva
T
The causative agent of rabies is a uniform virus, without different types or groups
F
The resistance of the rabies virus is good, it retains infectivity for several months in the environment
F
All warm-blooded animals are susceptible to rabies virus
T
Rabies virus is shed in high titre in the saliva
T
Paralysis is a clinical sign of rabies
T
Foxes are vaccinated with attenuated bait vaccine
T
Cattle bitten by rabid animals may be vaccinated post exposition or slaughtered
T
Humans can be infected with rabies, only by being bitten by rabid animals
F
Rabies virus is spreading along the nerves to the central nervous system
T
Rabies virus is shed in the saliva only after the appearance of the clinical signs
F
Focal necrosis in the liver is a typical lesion of rabies
F
Immunofluorescence test is widely used diagnostic method in the case of rabies
T
Virus neutralization test is used to the laboratory diagnosis of rabies cases
F
Dogs have to be vaccinated for the prevention of rabies at the age of 3 months for the first time
T
Increased salivation is a clinical sign of rabies
T
Always the furious form of rabies can be seen in dogs

furious or silent
Colic can be a sign of rabies in horses
T
Changed behaviour is a clinical sign of rabies of wild living animals
T
Only the classical rabies virus can cause clinical signs, the other genotypes not
F
The sylvatic form of rabies is maintained by different wild living animals
T
Rabies virus causes viraemia soon after infection
F
Saliva can contain rabies virus, before the appearance of clinical signs
