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
A chemical that kills or inhibits the growth of micro-organisms and is used in treating disease
Any of various substances, such as penicillin that are used to inhibit or destroy the growth of microorganisms in the prevention and/or treatment of disease
Chemical substance formed as a metabolic by-product in bacteria or fungi and used to treat bacterial infections Antibiotics can be produced naturally, using microorganisms, or synthetically
An antibiotic is a substance, produced by or derived from a microorganism (especially mold), that destroys or inhibits the growth of other microorganisms Antibiotics are used to treat infections caused by organisms that are sensitive to them, usually bacteria or fungi
Substance used to inhibit the growth of micro-organisms, including bacteria and fungi (10)
A natural of synthetic substance that inhibits growth of or destroys microorganisms, typically bacteria
a chemical substance derivable from a mold or bacterium that kills microorganisms and cures infections; "when antibiotics were first discovered they were called wonder drugs"
Drugs that kill or stop the growth of cells and that are derived from microbes, especially bacteria or fungi They are principally used to treat infectious diseases The classical example is penicillin In some cases, the antibiotics may be used as anticancer agents An example is the anthracycline agents
substance, such as penicillin or streptomycin, produced by or derived from certain fungi, bacteria, and other organisms, that can destroy or inhibit the growth of other microorganisms
Antibiotics are used in animal agriculture for two reasons First, to improve the rate of growth and the feed efficiency of animals so they produce more meat or milk on less feed The second reason is to prevent and treat diseases, just as in humans
