Antibiotics

特許 係属中 An antibiotic is an agent that either kills or inhibits the growth of a microorganism.[1][2] The term antibiotic was first used in 1942 by Selman Waksman and his collaborators in journal articles to describe any substance produced by a microorganism that is antagonistic to the growth of other microorganisms in high dilution.[3] This definition excluded substances that kill bacteria but that are not produced by microorganisms (such as gastric juices and hydrogen peroxide).
