It is needed to produce integrase.

Question 4. Which statement is true about fungal infections?


They occur only on skin, hair, and nails.

, They are controlled by phagocytes and T lymphocytes.


They result in release of endotoxins.


They are prevented by vaccines.

Explanation: The host defense against fungal infection includes the fungistatic

properties of neutrophils and macrophages. T lymphocytes are crucial in

limiting the extent of infection and producing cytokines to further activate

macrophages.




Question 5. Which statement about vaccines is true?


Most bacterial vaccines contain attenuated organisms.


Most viral vaccines are made by using dead organisms.


Vaccines require booster injections to maintain lifelong

protection.


Vaccines provide effective protection for all people against

viruses, bacteria, and fungal infections.

Explanation: In general, vaccine-induced protection does not persist as long as

infection-induced immunity, thus booster injections may be necessary

to maintain protection throughout life.
