Question 5

In the later 1800s,the brilliant French chemist Louis Pasteur worked with chicken cholera,passing the disease agent from sick to healthy chickens.He suspended his research and went on vacation for several weeks.When he returned,the old cholera culture he gave to healthy chickens failed to kill them.He assumed his culture was bad and injected these same chickens with a fresh culture of chicken cholera.These chickens remained healthy while new chickens injected with the fresh culture of chicken cholera rapidly became sick and died.From our current knowledge of immunity,how would these observations be explained?

Accepted Answer

A)  Pasteur had accidentally discovered a strain of chickens that had natural immunity.
B)  His first disease culture had weakened over time and stimulated the development of active immunity.

Question 8

In the late 1800s,a Frenchman observed that individuals who recovered from a disease were not susceptible to that same disease again.Therefore,he proposed that the agent that caused syphilis should be given to all young,healthy people as a vaccine to prevent them from getting a serious case of the disease.Although the mode of action of vaccines was not yet known,Pasteur argued vehemently against this proposal.Today,we do not follow this procedure for syphilis.Why?

Accepted Answer

A)  Vaccines only work against a few pathogens.
B)  Vaccines do not work for pathogens that are vulnerable to antibiotics.
C)  Syphilis is an autoimmune disease.
D)  It might work,but Pasteur was a famous authority and his ideas prevail today.

G) A) and E)
