Multiple Choice Questions

62. HIV/AIDS can be categorized as a new or emerging infectious disease.  By putting it into this category, we are effectively saying that

A. this infection hasn’t been observed in the human population prior to recent (approximately 50 years or sooner) outbreaks.

 

B. this disease has been in susceptible populations for centuries, but has only recently achieved infection levels that became detectable.

 

C. the infectious agent is still evolving and changing, unlike with older, more established diseases such as plague or polio.

 

D. the disease has always been in susceptible populations and causing disease, but we lacked the technology to detect it.

 

63. An illness outbreak occurs in New York City birds in the late 1990s.  After a lengthy scientific investigation, the Centers for Disease Control (CDC) determine that the agent causing the birds to die is the West Nile virus.  Outbreaks of this illness have been observed in several other countries in Asia and the Middle East across the last 50 years, but not in the United States.  With this information, what would be the best categorization of this infectious agent/disease?

A. This is clearly a reemerging infection.  It’s been around for a long time, and it is reappearing in a susceptible population again.

 

B. This is clearly a nosocomial infection.  It’s transmitted from animals to human beings in urban environments.

 

C. This is clearly an emerging infection.  It hasn’t been around that long, and it has made a jump across continents into a new susceptible population.

 

D. This is clearly not a concern to human beings-maybe it’s emerging in animals, maybe it’s reemerging, maybe it’s nosocomial.  But who cares?  It’s only in birds.

 

64. Why are we concerned at all with monitoring emerging/reemerging diseases?

A. These represent growing threats to human health that will require new scientific research and resources to effectively combat.

 

B. Because globalization (greater trade and travel between countries) leads to more chances for spread of illnesses into new areas and populations.  Monitoring these illnesses will help us to protect people.

 

C. Because the speed of travel has increased greatly.  With increased speed of travel, it is far more likely that a serious pathogenic threat from one area of the world can spread rapidly across the globe in a very fast manner.  We need to monitor the occurrence of these illnesses to try to protect populations.

 

D. All of the above.

 

65. A microbiologist obtained two pure isolated biological samples: one of a virus, and one of a viroid.  The labels came off during a move from one lab to the next, however.  The scientist felt she could distinguish between the two samples by analyzing for the presence of a single type of molecule.  What type of molecule would she be looking for to differentiate between the two?

A. DNA

 

B. protein

 

C. lipids

 

D. RNA

 

66. Within a lab, a scientist has two samples-the first is a prion sample, while the second is a viroid sample.  But those pesky labels have come off of the flasks!  She wants to run a simple analysis to determine which one is which.  What type of molecule would she look for to determine which one is which?

A. lipids

 

B. DNA

 

C. protein

 

D. polysaccharides

 

67. A scientist discovers a new species near coral reefs in Australia.  On basic microscopic examination and after conducting a few simple experiments, he finds that this single-celled species is photosynthetic (using sunlight for energy), has a rigid cell wall structure with no peptidoglycan, uses a flagellum for motion, and contains a variety of internal structures that are bound by plasma membranes.  Given this information, this new species is most likely a ______ cell in the _____ subcategory.

A. bacterial; eubacterial

 

B. eukaryotic; fungus

 

C. archaebacterial; fungus

 

D. eukaryotic; algae

 

E. eukaryotic; protozoan

 

68. Scientists recently cloned Louis Pasteur and put him back to work in a modern lab.  He promptly developed a gel that breaks down proteins.  Since he hasn’t been around for some time, he’s unsure what the best application for his invention might be.  Help him out-what pathogenic item would this gel be most effective and safe at eliminating?

A. Viroids on the surface of agricultural plant tissues.

 

B. Prions inside the central nervous system of cows.

 

C. Viruses on the surface of the skin.

 

D. Bacteria in the intestines of human beings.

Multiple Choice Questions

62. HIV/AIDS can be categorized as a new or emerging infectious disease.  By putting it into this category, we are effectively saying that

A. this infection hasn’t been observed in the human population prior to recent (approximately 50 years or sooner) outbreaks.

 

B. this disease has been in susceptible populations for centuries, but has only recently achieved infection levels that became detectable.

 

C. the infectious agent is still evolving and changing, unlike with older, more established diseases such as plague or polio.

 

D. the disease has always been in susceptible populations and causing disease, but we lacked the technology to detect it.

63. An illness outbreak occurs in New York City birds in the late 1990s.  After a lengthy scientific investigation, the Centers for Disease Control (CDC) determine that the agent causing the birds to die is the West Nile virus.  Outbreaks of this illness have been observed in several other countries in Asia and the Middle East across the last 50 years, but not in the United States.  With this information, what would be the best categorization of this infectious agent/disease?

A. This is clearly a reemerging infection.  It’s been around for a long time, and it is reappearing in a susceptible population again.

 

B. This is clearly a nosocomial infection.  It’s transmitted from animals to human beings in urban environments.

 

C. This is clearly an emerging infection.  It hasn’t been around that long, and it has made a jump across continents into a new susceptible population.

 

D. This is clearly not a concern to human beings-maybe it’s emerging in animals, maybe it’s reemerging, maybe it’s nosocomial.  But who cares?  It’s only in birds.

64. Why are we concerned at all with monitoring emerging/reemerging diseases?

A. These represent growing threats to human health that will require new scientific research and resources to effectively combat.

 

B. Because globalization (greater trade and travel between countries) leads to more chances for spread of illnesses into new areas and populations.  Monitoring these illnesses will help us to protect people.

 

C. Because the speed of travel has increased greatly.  With increased speed of travel, it is far more likely that a serious pathogenic threat from one area of the world can spread rapidly across the globe in a very fast manner.  We need to monitor the occurrence of these illnesses to try to protect populations.
