What is the Classic Approach for Finding New Antibiotics

Question

What is the classic approach for finding new antibiotics?
A) screening animals for secreted antimicrobial compounds
B) harvesting them from individuals with immunity
C) screening bacteria and fungi for secreted antimicrobial compounds
D) harvesting them from sick individuals
E) synthesizing them in the laboratory

Accepted Answer

The classic approach for finding new antibiotics is to screen bacteria and fungi for secreted antimicrobial compounds. This is because these microorganisms have evolved various defense mechanisms to compete with each other for resources and limiting factors in their environment, including the production of antimicrobial compounds. Therefore, screening these microorganisms for their secretions can lead to the discovery of new antibiotics.
