General microbiology

A. ELISA for HIV B. Immunogram C. Sternal puncture
D. X-ray of lungs E. Lymph node biopsy
20. The 28 y.o. woman applied to doctor because of limited loss of the hair. In the anamnesis - she had frequent headache indisposition, arthromyalgia, fever, irregular casual sexual life, drug user. RW is negative. What examination must be done first?
A. Examination for HIV B. Examination for neuropathology
C. Examination for gonorrhea
D. Examination for fungi E. Examination for trichomoniasis
21. Mass serological diagnosis of HIV infection is made by means of enzyme-linked immunosorbent assay techniques. What standard component of the reaction must be adsorbed on the solid phase of the test system?
A. HIV antigens B. Monoclonal HIV antibodies
C. Specific immunoglobulins D. Enzyme-marked HIV antibodies
E. Substrates to determine enzyme activity
22. A doctor was addressed by a 30-year old man. There is a probability of the patient being HIV-positive. To clarify the diagnosis the doctor proposed to perform polymerase chain reaction. The basic process in this kind of investigation is:
A. Gene amplification B. Transcription
C. Genetic recombination D. Genomic mutation
E. Chromosome mutation

A. Transcription B. Repair C. Replication
D. Reverse transcription E. Translation

SPECIAL BACTERIOLOGY
Staphylococcus
1. At the laboratory experiment the leukocyte culture was mixed with staphylococci. neutrophile leukocytes engulfed and digested bacterial cells. This process is termed:
A. Phagocytosis B. Pinocytosis C. Diffusion
D. Facilitated diffusion E. Osmosis
2. In the surgical department of a hospital there was an outbreak of hospital infection that showed itself in often postoperative wound abscesses. Bacteriological examination of pus revealed aurococcus. What examination shall be conducted to find out the source of this causative agent among the department personnel?
A. Phagotyping B. Microscopical examination
C. Serological identification D. Biochemical identification
E. Estimation of antibiotic susceptibility
3. Because of suspected intrahospital infection in the neonatal department of the maternity home the inspection was carried out. In some children and on some general things Staphylococcus aureus was revealed. What properties of these cultures allow to establish their origin from one source?
A. Antibioticogramma B. Antigenic structure
C. Biochemical activity D. Phagotype
E. Chromogenesis
4. In the surgical department of a dental clinic cases of hospital-acquired staphylococcal infection were registered which was caused by strains with multiple drug resistance. Such feature can be identified by presence of:
A. R-plasmids B. F-plasmids C. Exotoxins
D. Temperate bacteriophages E. Virulent bacteriophages
5. Staphylococci grow well in ordinary media but inoculation of blood and egg-yolk salt agar should be done to separate pure bacterial cultures from diseased tissue. What is the purpose of those media?
