Which of the following pairs is mismatched?

a. Ehrilich - chemotherapy

b. Koch - antibiotics

c. Pasteur - proof of biogenesis

d. Jenner - vaccination

e. None of the above

The correct answer is option b. "Koch - antibiotics".

Explanation:

The discovery and development of antibiotics is attributed to Sir Alexander Fleming. This Scottish biologist discovered penicillin in 1928, the first true antibiotic, when he studied a blob of mold that prevented the growth of colonies of Staphylococcus. Robert Koch was an important scientist considered a founder of modern bacteriology, but he is not related with the discovery of antibiotics. Koch died in 1910, years before penicillin was discovered.

The answer is

b. Koch - antibiotics

Explanation:

a)

Paul Ehrlich is considered to be the "father of chemotherapy", so this matching is correct.

b)

The first antibiotic identified was the penincilin, by Alexander Fleming, in 1928, 18 years after Koch had died.

Koch had an important role in combating epidemies, however he did not identify the antiniotics, so this pair is mismatched

c)

This is the production of new living organisms or organelles, proved by Louis Pasteur. So this pair is correctly matched.

d)

Jenner introduced the smallpox vaccine in 1796. So this pair is correctly matched.
