Quiz 1 Study Questions
1.What is the role of reverse transcriptase in HIV infection?
- It converts RNA into double-stranded DNA.
2. What of the following remains a significant - Infectious disease
3. Which statement is true about fungal infections?
- They are controlled by phagocytes and T lymphocytes.
4. Which statement about vaccines is true?
- Vaccines require booster injections to maintain lifelong protection.
5. After sexual transmission of HIV, a person can be infected yet seronegative for _____ months.
- 6 to 14
6. Once they have penetrated the first line of defense, which microorganisms do neutrophils actively attack, engulf, and destroy by phagocytosis?
- Bacteria
7. What is the mechanism in type II hypersensitivity reactions?
- Antibodies bind to the antigens on the cell surface.
8. What is the mechanism in type III hypersensitivity reactions?
- Antibodies bind to soluble antigens that were released into body fluids and the immune complexes are deposited in the tissues.

- DiGeorge syndrome
11. A person with type O blood is likely to have high titers of anti-___ antibodies.
- A and B
12. During an IgE-mediated hypersensitivity reaction, what causes bronchospasm?
- Smooth muscle contraction caused by histamine bound to H 1receptors
13. In a type II hypersensitivity reaction, when soluble antigens from infectious agents enter circulation, tissue damage is a result of
