In order to estimate toxigenity of diphtheria agents obtained from patients the cultures were
Inoculated on Petri dish with nutrient agar on either side of a filter paper strip that was put into
The centre and moistened with antidiphtheric antitoxic serum. After incubation of inoculations in
Agar the strip-like areas of medium turbidity were found between separate cultures and the strip
Of filter paper. What immunological reaction was conducted?
A Precipitation gel reaction
B Coomb's test
C Agglutination reaction
D Rings precipitation reaction
E Opsonization reaction
52
A patient with clinical signs of encephalitis was delivered to the infectious diseases hospital.
Anamnesis registers a tick bite. Hemagglutination-inhibition reaction helped to reveal antibodies
To the causative agent of tick-borne encephalitis in the dilution 1:20 which is not diagnostic.
What actions should the doctor take after he had got such result?
A To repeat the examination with serum taken 10 days later
B To examine the same serum
C To apply more sensitive reaction
D To repeat examination with another diagnosticum
E To deny diagnosis of tick-borne encephalitis
53
The first grade pupils were examined in order to sort out children for tuberculosis revaccination.
What test was applied for this purpose?
A Mantoux test
B Schick test
C Supracutaneous tularin test
D Burnet test
E Anthraxine test
54
Clinical diagnosis of a female patient was gonorrhoea. What examination method can be
Applied for confirmation of this diagnosis?
A Microscopy of pathological material
B Infection of laboratory animals
C Test with bacteriophage
D Hemagglutination reaction
E Immobilization reaction
55

56
Bacteriological laboratory examines canned meat whether it contains botulinum toxin. For this
Purpose an extract of test specimen and antitoxic antibotulinic serum of A, B, E types were
Introducted to a group of mice under examination; a control group of mice got the extract without
Antibotulinic serum. What serological reaction was applied?
A Neutralization
B Precipitation
C Complement binding
D Opsono-phagocytic
E Double immune diffusion
57
For the purpose of retrtospective diagnostics of recent bacterial dysentery it was decided to
Perform serological examination of blood serum in order to determine antibody titer towards
Shiga bacilli. What of the following reactions should be applied?
A Passive hemagglutination
B Bordet-Gengou test
C Precipitation
D Hemolysis
E Bacteriolysis
58
During the repeated Widal's agglutination test it was noticed that the ratio of antibody titers and
O-antigens S.typhi in the patient's serum had increased from 1:100 to 1:400. How would
You interpret these results?
A The patient has typhoid fever
B The patient is an acute carrier of typhoid microbes
C The patient is a chronic carrier of typhoid microbs
D The patient previously had typhoid fever
E The patient was previously vaccinated against typhoid fever
59
A patient recovered from Sonne dysentery and was once more infected with the same
Causative agent. What is such infection form called?
A Reinfection
B Recidivation
C Superinfection
D Persisting infection
E Chronic infection
