SPECIAL VIROLOGY Influenza viruses 1. Ambulace brought to the hospital a patient with acute respiratory viral infection. The illness began suddenly with temperature rise up to 39,90 C. He complains of headache in frontotemporal lobes, pain in eyeballs, aching of the whole body, nose stuffiness, sore throat, dry cough. At home he had a nasal hemorrhage twice. What type of acute respiratory viral infection is it?
A. Influenza B. Adenoviral infection
C. Parainfluenza D. RS-infection E. Enterovirus infection
2. Material taken from a patient with provisional diagnosis "influenza"was referred to a laboratory. For virological examination the hemadsorption reaction was applied. This reaction can be applied for detection of the following viruses:
A. Viruses containing hemagglutinins B. All the simple viruses C. All the complex viruses
D. DNA-genomic viruses E. Any viruses
3. During the breakout of acute respiratory infection in order to diagnose influenza the express-diagnosis, based on revealing of specific viral antigen in the examined material (nasopharyngial lavage), is carried out. Which reaction is used for this?
A. Immunofluorescence B. Agglutination
C. Precipitation D. Opsonization E. Complement binding
4. A virological laboratory obtained pathological material (mucous discharges from nasal meatuses) taken from a patient with provisional diagnosis "influenza". What quick test will allow to reveal specific viral antigen in the material under examination?
A. Direct and indirect immunofluorescence test B. Direct and indirect fluorescence immunoassay
C. Hemagglutination inhibition assay
D. Radioimmunoassay E. –
5. Pathological material (mucosal excretion from the nasal passages) taken obtained from a patient provisionally diagnosed with influenza was delivered to the virological laboratory. What quick test allows detecting specific viral antigen in the investigated material?
