MICROBIOLOGY EXAM 6 WITH SATISFIED SOLUTIONS GRADED A+

What is the most efficient and cost-effective way to control infectious diseases? - active immunization by vaccination

A viral neutralization test detects - patient antibodies specific for a virus.

Killed vaccines work by stimulating - an antibody response.

A person who has been exposed to rabies receives both HRIG (human rabies immunoglobulin) injected near the bite site and the rabies vaccine. What does this strategy represent? - active immunization combined with passive immunotherapy

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? - inactivated whole

Contact immunity within a population can be produced by ________ vaccines. - attenuated

Almost a century after Edward Jenner introduced successful vaccination, Louis Pasteur developed vaccine(s) against - both anthrax and rabies.

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

The complement fixation test uses red blood cells as the target for complement activation. Test serum containing antibodies is combined with a known amount of antigen in a tube, and then the RBCs and antibodies against the RBCs are added. A positive result for the complement fixation test would be - a cloudy solution in the tube.


An indirect fluorescent antibody test detects - antibodies specific for an antigen.

A(n) ________ assay is used for rapid identification of strep (group A Streptococcus) infections. - immunochromatographic

The first true vaccine provided immunity to - smallpox.

The concentration (or titer) of an antibody to a specific antigen can be determined using a(n) ________ test. - agglutination

In precipitation tests, maximum precipitation takes place when - the amount of the antibody and the amount of the antigen are at optimal proportions.

Which of the following statements regarding toxoids is FALSE? - They provide lifelong immunity.

Which of the following is a possible side effect of immunization with an inactivated vaccine? - both allergic reaction and toxicity

Serologic tests may be used to detect ________ for diagnosis of disease. - antigen-specific antibodies

A hemagglutination test is useful for - blood typing.

Antivenin is a(n) - antitoxin used to treat exposure to a venom

The attenuated oral poliovirus vaccine (OPV) is no longer administered in the U.S.A. because it - Can be spread to contacts and can occasionally cause poliomyelitis

Viruses that naturally cause clumping of red blood cells can be diagnosed using a(n) ______ test - Viral hemagglutination

The discovery of antibodies and the understanding of their actions lead to - the development of passive immunotherapy
