Principle of virus neutralization test:
- Highly specific test based on the neutralisation of the virus by specific antibodies in serum tested
- Positive = serum contains specific antibodies that neutralise virus and virus can not damage the cells
- Negative = No antibodies, virus is not neutralised and can cause cytopathic effect

.a) Primary and established
.b) Monolayers and established
.c) Monolayers and suspension
.c) Monolayers and suspension
Which medium is used for cultivation of fungi:
.a) Towenstein-Jenssen
.b) Hepatic agar
.c) Sabourad agar

Which is the gold standard test for laboratory diagnosis of rabies:
.a) Fluorescent antibody test
.b) Biological experiment
.c) Agglutination assay
.a) Fluorescent antibody test
OIE is:
.a) Organisation of internal disease elimination
.b) World health organization
.c) World health organization for animal health
.c) World health organization for animal health
Stages of infectious process:
- Incubation period
- Prodromal period
- Manifestation period
- Final period (recovery or death)
What does the approach to one health mean:
- It recognises the interrelationship between animal, human and environmental health
Source of infection is:
.a) Macroorganisms, in which etiological agent survives, multiplies and is excreted
.b) Macroorganisms, in which etiological agent survives and multiplies
.c) Macroorganisms, in which etiological agent survives and is excreted
.a) Macroorganisms, in which etiological agent survives, multiplies and is excreted
