Deck 3 Flashcards
What is the principle of haemagglutination inhibition test:
Serological test – Antibody detection. Has the ability of the specific ab to
inhibit haemagglutination activity of some viruses (hemagglutinin)
identification – parvovirus, parainfluenza virus, adenovirus…
Division of the media used for cell culture:
(MCQ) Natural, synthetic.
Complement fixation test is used for detection of:
(MCQ) Antibody
In sandwich ELISA positive result is:
(MCQ) Change of colour.
Carnivores are born:
(MCQ) Hypogammaglobulinemic
What are tropisms of pathogens:
Monotropic, pantropic, polytropic.
Name at least three tests for cellular immunity evaluation:
Flow cytometry, Fluorescence technique, CBC (complete blood count).
(+ Immunoglobulin test, Lymphocyte proliferation assay)
What is abortive infection:
(MCQ) Infection that disappears after prodromal period.
What is the role of colostral immunity:
Provide passive immunity. Protection against septicaemia and organ
infection. Local protection of intestine. GIT multiplication of bacteria.
10.Clinical signs indicating failure of passive transfer of immunity (FPTA):
In 3-5 days old animal: Profuse diarrhea, dehydration, resp. or systemic
infections.
What is the principle of AGID (agar gel immunodiffusion) test:
Specific Ag put in a centre hole, surrounded by 6 wells with tested serum
positive has recipitation line between Ag and Ab
Division of the media used for cell culture:
(MCQ) Natural, synthetic
In blocking ELISA positive result is:
(MCQ) No colour
Give an example of facultative pathogens:
Bacteria’s; Salmonella, Staphylococcus spp., Listeria spp., Pseudomonas
aeruginosa.
Animal notifiable diseases are reported to:
(MCQ) World organization for animal health
