"Antibiotics kill disease-causing organisms."

Brief explanation: The medical significance was that antibiotics (like penicillin) could specifically kill or inhibit pathogenic bacteria, allowing effective treatment of bacterial infections that were often fatal before. They do not kill all living organisms, and they do not work against viruses; they can, however, sometimes be used prophylactically to prevent infections.
