UAMS IMMUNOLOGY EXAM 5 REVIEW VIROLOGY
UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS

Question:
1. Virus
Answer:
Submicroscopic particles; obligate intracellular parasites that require living cells to replicate

Question:
2. Genome
Answer:
Either RNA or DNA

Question:
3. Capsid
Answer:
protein shell that encloses the viral genome

Question:
4. Capsomere
Answer:
subunit of the capsid

Question:
5. Neucleocapsid
Answer:
capsid with enclosed genome

Question:
6. Viral envelope
Answer:
A membrane that cloaks the capsid that in turn encloses a viral genome.

Question:
7. Virion
Answer:
a fully formed virus that is able to establish an infection in a host cell

Question:
8. Viral infection mechanism
Answer:
Attachment > Penetration > Uncoating > Transcription > Translation > Assembly > Budding > release

, Question:
9. Classification of viruses
Answer:
Type of nucleic acid and configuration; viral replication, virion

Question:
10. Virus major routes into the body
Answer:
Mucous membranes, skin, inhalation

Question:
11. Laboratory detection of viruses
Answer:
serology, electron microscopy, cytology, antigen detection, cell culture, and molecular testing

Question:
12. Viral serology
Answer:
detection of patient antibodies to the virus. IgM tests detect recent infections

Question:
13. Viral electron microscopy
Answer:
-Viruses are sufficiently unique in a structure that they can be differentiated into families as genes

Question:
14. viral cytology
Answer:
Tznack prep; FIA

Question:
15. Tznack Prep
Answer:
Host cells are stained with dyes and observed for characteristic morphology

Question:
16. FIA
Answer:
Staining is more sensitive that dye based staining

Question:
17. Viral antigen detection
Answer:
Immunofluorescence; enzyme immunoassay, latex agglutination, and rapid immunochromatographic
membrane assay
