    Antibiotic, chemical substance produced by a living organism, generally a microorganism, that is detrimental to other microorganisms. Antibiotics commonly are produced by soil microorganisms and probably represent a means by which organisms in a complex environment, such as soil, control the growth of competing microorganisms. Microorganisms that produce antibiotics useful in preventing or treating disease include the bacteria and the fungi. A decade later British biochemist Ernst Chain, Australian pathologist Howard Florey, and others isolated the ingredient responsible, penicillin, and showed that it was highly effective against many serious bacterial infections. A dramatic episode in medical history occurred in 1928, when Alexander Fleming noticed the inhibitory action of a stray mold on a plate culture of staphylococcus bacteria in his laboratory at St. Toward the end of the 1950s scientists experimented with the addition of various chemical groups to the core of the penicillin molecule to generate semisynthetic versions. A range of penicillins thus became available to treat diseases caused by different types of bacteria, including staphylococci, streptococci, pneumococci, gonococci, and the spirochaetes of syphilis. As well as being dramatically effective against tuberculosis, streptomycin demonstrated activity against many other kinds of bacteria, including the typhoid fever bacillus. Discovered in 1939 by French-born American microbiologist René Dubos, they were valuable in treating superficial infections but were too toxic for internal use. In the 1950s researchers discovered the quinolones. Quinolones interrupt the replication of DNA—a crucial step in bacterial reproduction—and have proven useful in treating urinary tract infections, infectious diarrhea, and various other infections involving elements such as bones and white blood cells. Others, such as the tetracyclines, act against a broad spectrum of different bacteria.

    Amoxicillin is a semisynthetic (synthesized from naturally occurring substance) aminopenicillin antibiotic structurally related to ampicillin. It is a moderate-spectrum antibiotic active against a wide range of Gram-positive, and limited number of Gram-negative bacteria. Amoxicillin was discovered by scientists at Beecham Research Laboratories in 1972. In the US it is marketed by Glaxo Smith Kline (the inheritor company) under the original trade name Amoxil. The narrow antimicrobial spectrum of penicillins, led to the search for derivatives of penicillin which could treat a wider range of infections. The first important step forward was the development of ampicillin. Ampicillin had a broader spectrum of activity than either of the original penicillins and allowed doctors to treat a broader range of both Gram-positive and Gram-negative infections.
