Deck 3 Flashcards
What is the one health concept?
human health and animal health are interdependent and bound to the health of the ecosystem in which they exist
Natural focus of the infection is limited:
a) by age and season
b) geographically and seasonally
c) by susceptibility of the macroorganism
geographically and seasonally
Young ruminants are born:
a) agammaglobulinemic
b) hypogamaglobulinemic
c) hypergamaglobulinemic
agammaglobulinemic
Phylogenetic tree shows:
a) in graphic form, developmental relationship between studied strains
b) in graphic form, origin of the diseases
c) in graphic form, process of pathogen mutation
in graphic form, developmental relationship between studied strains
What are grades of epizootic process
sporadic: occurs irregularly
enzootic: continuously present in a location during longer time period
epizootic: occurs in excess of normal expectancy
panzootic: occurring over a very wide area and affecting large population
What are the main reagents of PCR?
primers, enzyme (Taq DNA polymerase), DNA sample, dNTP
Principle of virus neutralisation test
a highly specific test based on the neutralisation of the virus by specific antibodies in the serum tested
positive serum contains Ab that neutralise the virus and consequently the virus cannot damage the cells
Division of cell cultures according to the way of cultivation:
a) primary and established
b) monolayers and established
c) monolayers and suspension
monolayers and suspension
OIE is:
a) Organisation of internal disease elimination
b) World health organisation
c) World health organisation for animal health
world health organisation for animal health
(office international des epizooties)
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
macroorganisms, in which aetiological agent survives, multiplies and is excreted
Blocking ELISA is used for detection of:
antibodies
WHO is:
a) World health organisation
b) Food and agriculture organisation
c) World animal health information database
world health organisation
For detection of antibodies we use:
a) Sandwich ELISA
b) Indirect ELISA
c) Competitive ELISA
b) Indirect ELISA
what is the principle of immunofluorescence
to use marked Ab of immune serum against Ag which we want to visualise
define indirect transmission
the passage of infectious agent between individuals through the medium of inanimate or animate objects
the period between contamination of the object and subsequent exposure of susceptible individuals is highly variable and may range from a few minutes to a few years
