Exam 17: Immunization and Immune Testing

A technician places a serum sample in a well in an agar plate and a solution of antigens in a second well in the plate. The technician has set up a(n) (agglutination/immunodiffusion/immunoblot) assay.

Killed vaccines work by stimulating

Analysis of blood to detect specific antigens or antibodies is known as

Which of the following diagnostic procedures depends on precipitation of antigen-antibody complexes?

How has modern technology helped to produce new types of vaccines?

The polio vaccine currently administered in the U.S., known as IPV, is an example of a(n) ________ vaccine.

Tuberculosis may be diagnosed using a(n) ________ on sputum (lung fluid) samples.

Deliberate infection of young children with particles of ground smallpox scabs from children who had survived mild cases of smallpox was known as (vaccination/variolation/immunization).

An advantage of (attenuated/inactivated/subunit) vaccines is that they usually elicit cell-mediated immune responses.

An infectious disease researcher isolates the pathogen responsible for an emerging disease. The microbe is grown in the lab. A preparation of the laboratory-grown microbe is treated with a lethal dose of ionizing radiation and then tested for its potential as a vaccine. What type of vaccine is this?

Which of the following substances is commonly used to inactivate microbes?

Compare and contrast viral neutralization and viral hemagglutination tests.

The "dipstick" illustrated in Figure 17.3 is used in a(n) (immunodiffusion/immunochromatographic/ immunofluorescent) assay.

Which of the following statements regarding toxoids is FALSE?

Rabies virus can be directly detected in brain tissue using a(n) ________ assay.

Passive immunotherapy does not result in immunological memory.

In precipitation tests, maximum precipitation takes place when

Antisera directed against toxins are known as (antibodies/antitoxins/anti-antibodies).

One way to measure the antibody levels in the blood is by (neutralization/titration/turbidimetry) using agglutination tests.

Anti-antibodies are used in indirect antibody assays.
