A  The available treatment options are quite aggressive, including removal of damaged tissue in an effort to contain the infection.

B  MRSA is not typically associated with the type of infection that George has.

C  MRSA is transmissible.    

D  There are no effective antibiotic options for treating MRSA.  

A  The cost of producing antibiotics is high, which in turn leads to higher prices for consumers. Mass production of antibiotics is extremely difficult.

B  The cost of producing antibiotics is high, which in turn leads to higher prices for consumers. Treatment with antibiotics can lead to the emergence of resistant strains. Mass production of antibiotics is extremely difficult.

C  Antibiotics may be toxic. Antibiotics are not effective in treating viral infections. Treatment with antibiotics can lead to the emergence of resistant strains.

A  Inject the S. aureus strain into an animal and see whether it develops the same type of infection that George has.  

B  Inject the S. aureus into an animal, observe whether the animal gets an infection similar to George’s, and isolate the same strain of S. aureus from the infection.  

C  Inject the S. aureus into an animal; if the animal develops the same infection, isolate the infectious material from the animal and test its ability to vaccinate another animal.

D  Compare the DNA sequence of the strain of S. aureus isolated from George to other S. aureus strains to see whether it has been isolated from other similar infections.  

A  Since the broth had been heated (effectively sterilizing it), no microbes would grow in the broth.  

B  The broth would become contaminated with microbes because they were trapped in the neck.  

C  The broth would remain uncontaminated because no microbes could enter the long S-shaped neck of the flask.  

D  Microbes would grow in the broth because the tipping would introduce the oxygen necessary for microbial growth.  

A  The results of his experiment demonstrated that living organisms are derived from other living organisms.

B  His experiments demonstrated that oxygen is essential to all life.

C  His experiments determined a series of conditions that must be satisfied in determining the causative agent of disease.

D  He determined that material from an infectious agent taken from one person could be used to stimulate immunity in another person.
