Question

Aureomycin was mainly developed by
A. Benjamin Minge Duggar
B. Robert Brown
C. K. R. Porter
D. None of the above

Answer 1

Aureomycin or chlortetracycline is a tetracycline antibiotic. This antibiotic is mainly used as veterinary medicine to treat conjunctivitis in cats, dogs and horses, respiratory tract infections in calves, pigs and chicken and open infected wounds in cattle, sheep and pigs.

Complete Answer:
Let us look at each option one by one.
- Benjamin Minge Duggar was an american plant physiologist; but rather than his achievements in botany, he is well known for the discovery of chlortetracycline (aureomycin), the first of many tetracycline antibiotics from a soil bacteria in the late 1940s. Therefore, this is the correct option.
- Robert Brown was a Scottish botanist and paleobotanist. He is best known for the discovery of the cell nucleus using a microscope as well as the discovery of the ‘Brownian Motion’. He did not discover any antibiotic. Therefore, this option is incorrect.
- Keith R. Porter was a Canadian-American cell biologist. He was known to some people as the father of biological electron microscopy due to his pioneering works in biological research using electron microscopy of the cells. He did not discover any antibiotics. Therefore, this option is incorrect.
- Since option (A) is the correct choice, therefore, none of the above cannot be an answer to this question. Therefore, this option is incorrect.

Thus, the correct answer to this question is (A) Benjamin Minge Duggar.

Note: Studies have found that chlortetracycline is a wide range antibiotic having significant effects on both gram positive and gram negative bacteria along with chlamydiae, mycoplasmas, rickettsiae, and protozoan parasites.
