A chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.
Molecules or agents produced by microorganisms that have the capacity to kill or inhibit the growth of other microorganisms.
A drug used to treat infections caused by bacteria and other microorganisms.
A substance that inhibits the growth of microorganisms usually produced by other organisms such as penicillin.
Organic compound that is naturally formed and secreted by various species of microorganisms and plants. It has a defensive function and is often toxic to other species (e.g., penicillin, originally produced by bread mold, is toxic to numerous human pathogens). Antibiotics act by inhibiting protein and nucleic acid (DNA and RNA) biosynthesis, hence killing the cells involved. Inorganic molecules may also have antibiotic properties.
An agent with biological activity that inhibits the growth of microorganisms (bacteria, fungus, etc.)
Drugs that kill or inhibit the growth of disease-causing bacteria and other infections microbes. They are available in many forms, including pills, creams, and eye and ear drops, to treat a wide range of infections.
A drug that selectively attacks microorganisms by breaking down bacteria and prevents the growth of bacteria. Specific antibiotic drugs will work only against certain bacteria, leaving other bacteria unharmed.
Natural substance that inhibits growth or destroys micro-organisms. Used to treat infectious diseases.
An anti-infective drug that inhibits growth of or destroys microorganisms q.v. and is used extensively in treating bacteria-caused diseases.
Any drug containing any quantity of any chemical substance produced by a microorganism which has the capacity, in dilute solution, to inhibit the growth of, or to destroy, bacteria and other microorganisms (or a chemically synthesized equivalent of such a substance). Antibiotics are used in the treatment of infectious diseases.
Any of a variety of natural or synthetic substances that inhibit the growth of or destroy microorganisms. Used in the treatment of infectious diseases.
Drugs used to fight infections. They destroy microorganisms such as bacteria or fungi, but are not effective against viruses.
Drugs that inhibit growth of (or kill) pathogens.
Chemotherapeutic agents evolved by growing moulds of bacteria, and extracted from filtrates of the culture medium used for the growth. The antibiotic substance is then sterilized, purified, and frequently chemically manipulated to add to or enhance existing qualities {see, for example, penicillin). After estimation of the bactericidal or bacteriostatic strength the finished product is (usually) freeze-dried, and carries a statement as to unitage or weight of the active principle present.
Drug (e.g., penicillin), derived from a microorganism or produced synthetically, that destroys or limits the growth of a living organism, a disease-producing bacterium (e.g.. Streptococcus) or fungus.
Complex molecule (immunoglobulin), produced by lymph tissue in response to the presence of an antigen (such as a protein of bacteria or other infecting organism), that neutralizes the effect of the foreign substance.
Category of medications that treat bacterial infections.
Among the first antibiotic to be used to treat disease was penicillin.
Drugs used to treat bacterial infection. Originally, antibiotics were defined as substances produced by one microorganism that selectively inhibit the growth of another microorganism, but that strict definition is not always accurate because synthetic antibiotics are also available.
These antibacterial agents were originally derived from micro-organisms, although most of them are now prepared synthetically. Such agents destroy or inhibit the growth of other micro-organisms: examples are penicillin, cephalosporin, amino-glycosides, streptomycin, and tetracycline.
Destroys or inhibits the growth of micro-organisms, especially bacteria.
A substance produced by or derived from a microorganism that kills or inhibits the growth of other microorganisms.
A substance that kills or inhibits the growth of living microorganisms, especially bacteria, that are found in the gastrointestinal tract. From the Greek: “anti,” (against) and “biotics” (life).
A bioactive compound originating from mold or bacteria, which possesses the property of retarding the growth of microorganisms.
Microbial metabolites are compounds synthesized by microorganisms that possess the capability to impede the proliferation of other microorganisms or even exterminate them.
A compound obtained from living microorganisms, particularly fungi, that can either destroy or impede the growth of germs within the body.
