S. aureus has been isolated from George's infected wound. To satisfy Koch's postulates, what would George's doctor need to do with the isolated S. aureus?
a. Inject the S. aureus strain into an animal and see whether it develops the same type of infection that George has.
b. 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.
c. 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.
d. 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.
Ans: c. 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.
