antibioticadjective Relating to the destruction of living things noun Medtalk
antibioticany substance produced by a microorganism that even in low concentrations can inhibit or kill other microorganisms. For example, PENICILLIN produced by the fungus Penicillium chrysogenum prevents the reproduction of many bacteria by preventing cell-wall synthesis. Antibiotics are frequently the products of secondary metabolism in that, while not of major importance, their formation presumably offers a selective advantage to the organism. The amount of antibiotic produced per gram of producer can be greatly enhanced by optimal culturing conditions and strong selection pressure over many generations. Unfortunately, most antibiotics are not lethal to viruses. Furthermore, continued use of an antibiotic against a generally susceptible strain of bacteria will favour survival of the few resistant members of the bacterial population, resulting eventually in an antibiotic-resistant strain.
