Množina: antibiotics

A chemical substance derivable from a mold or bacterium that kills microorganisms and cures infections; SYN. antibiotic drug, wonder drug.
(substance) active against disease bacteria, obtained from a living organism such as a mold (fungus) or bacterium.
Drug that kills or inhibits the growth of bacteria and fungi. It is derived from living organisms such as fungi or bacteria, which distinguishes it from synthetic antimicrobials.
The earliest antibiotics, the penicillins, came into use from 1941 and were quickly joined by chloramphenicol, the cephalosporins, erythromycins, tetracyclines, and aminoglycosides. A range of broad-spectrum antibiotics, the 4-quinolones, was developed 1989, of which ciprofloxacin was the first. Each class and individual antibiotic acts in a different way and may be effective against either a broad spectrum or a specific type of disease-causing agent. Use of antibiotics has become more selective as side effects, such as toxicity, allergy, and resistance, have become better understood. Bacteria have the ability to develop resistance following repeated or subclinical (insufficient) doses, so more advanced and synthetic antibiotics are continually required to overcome them.
