Antibiotics
Abstract
Antibiotics can be defined as chemical substances capable of inhibiting the growth of microorganisms. In the past decades, numerous compounds possessing various biological activities have been discovered. Antibiotics can be of microbial origin, semisynthic, or totally synthetic. Their classification is based mostly on structural characteristics. This article gives a comprehensive overview of the classes, production, and uses of antibiotica.
