BIO 420 Final Exam Questions With
Correct Answers
What conditions still warrant the use of passive immunization? -
| | | | | | | | | |
ANSWER✔✔✔-Immune deficiency, especially congenital or acquired B- | | | | | |
cell defects, toxin or venom exposure with an immediate threat to life,
| | | | | | | | | | | |
exposure to pathogens that can cause death faster than an effective
| | | | | | | | | | |
immune response can develop
| | |
What is a disadvantage of attenuated vaccines? - ANSWER✔✔✔-Live
| | | | | | | | |
forms can sometimes mutate and revert to a more virulent form in the
| | | | | | | | | | | | |
host.
Which of the following is a form of passive immunization? -
| | | | | | | | | | |
ANSWER✔✔✔-Transfer of serum from an immune individual to a | | | | | | | | |
susceptible one, injection of rattlesnake antivenom to a snakebite
| | | | | | | | |
victim, infusion of cancer-specific CAR-T cells into a cancer patient.
| | | | | | | | |
Which of the following is a form of active immunization? -
| | | | | | | | | | |
ANSWER✔✔✔-Recovery from an acute viral infection, vaccination with | | | | | | | |
attenuated measles virus, vaccination with the killed polio virus.
| | | | | | | |
, What is a strategy for generating an attenuated vaccine? -
| | | | | | | | | |

| | | | | | | | | | | |
ANSWER✔✔✔-Safety
What is meant by "herd immunity"? - ANSWER✔✔✔-Vaccination of a
| | | | | | | | | |
percentage of individuals to prevent transmission to others
| | | | | | |
Humoral - ANSWER✔✔✔-Antibody (especially secretory IgA)
| | | | |
IgG, IgM, and IgA antibody
| | | |
IgG and IgM antibody
| | |
IgM antibody
|
Complement activated by IgG or IgMantibody:Blocks binding of virus to
| | | | | | | | | |
host cells, thus preventing infection or reinfection
| | | | | |
Block fusion of viral envelope with host cell's plasma membrane
| | | | | | | | |
Enhance phagocytosis of viral particles (opsonization)
| | | | |
Agglutinates viral particles | |
