Any substance that can destroy or inhibit the growth of bacteria and similar microorganisms
A substance, naturally produced by a micro-organism, capable of preventing the growth of other micro-organisms, particularly bacteria
Antibiotics are medical drugs used to kill bacteria and treat infections. Your doctor may prescribe a course of antibiotics. a drug that is used to kill bacteria and cure infections (anti- + biotic (19-21 centuries) (from bioticus, from , from bios )). Chemical substance that in dilute solutions can inhibit the growth of microorganisms or destroy them with little or no harm to the infected host. Early antibiotics were natural microbial products, but chemists have modified the structures of many to produce semisynthetic and even wholly synthetic ones. Since the discovery of penicillin (1928), antibiotics have revolutionized the treatment of bacterial, fungal, and some other diseases. They are produced by many actinomycetes (e.g., streptomycin, tetracycline) and other bacteria (e.g., polypeptides such as bacitracin) and by fungi (e.g., penicillin). Antibiotics may be broad-spectrum (active against a wide range of pathogens) or specific (active against one, or one class). Drawbacks include activity against beneficial microorganisms, often causing diarrhea; allergies; and development of drug-resistant strains of the targeted microorganisms
A chemical agent that is produced by one organism that is harmful to another organism
A class of natural and synthetic compounds that inhibit the growth of or kill other microorganisms (See Antibiotic resistance, Bacteriocide, Bacteriostat )
Drugs used to kill organisms that cause disease Antibiotics may be made by living organisms or they may be created in the lab Since some cancer treatments can reduce the body's ability to fight off infection, antibiotics may be used to treat or prevent these infections
A class of natural and synthetic compounds that inhibits the growth of, or kills, other microorganisms
a substance that can inhibit or destroy susceptible microorganisms, including disease-producing bacteria and fungi In the Galloway by Choice program antibiotics are used carefully and sparingly Antibiotics are used only when necessary, only for specific disease control, only as directed, and never in the finishing period
