Sir Alexander Fleming, a Scottish biologist, defined new horizons for modern antibiotics with his discoveries of enzyme lysozyme (1921) and the antibiotic substance penicillin (1928). The discovery of penicillin from the fungus Penicillium notatum perfected the treatment of bacterial infections such as, syphilis, gangrene and tuberculosis.
An antibiotic is a type of antimicrobial substance active against bacteria and is the most important type of antibacterial agent for fighting bacterial infections.Antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria.A limited number of antibiotics also possess antiprotozoal activity.
This article gives a very brief overview of the antibiotic era, beginning from the discovery of first antibiotics until the present day situation, which is marred by the emergence of hard-to-treat multiple antibiotic-resistant infections. The ways of responding to the antibiotic resistance ...
The discovery of penicillin and the initial recognition of its therapeutic potential occurred in the United Kingdom, but, due to World War II, the United States played the major role in developing large-scale production of the drug, thus making a life-saving substance in limited supply into a widely available medicine.
Antibiotics transformed medicine. The discovery of antibiotics began by accident. On the morning of September 3rd, 1928, Professor Alexander Fleming was having a clear up of his cluttered laboratory. Fleming was sorting through a number of glass plates which had previously been coated with staphyloccus bacteria as part of research Fleming was doing.
The discovery of penicillin, one of the world’s first antibiotics, marks a true turning point in human history — when doctors finally had a tool that could completely cure their patients of ...
This became the first modern antibiotic, although Ehrlich himself referred to his discovery as 'chemotherapy' – the use of a chemical to treat a disease. The word 'antibiotics' was first used over 30 years later by the Ukrainian-American inventor and microbiologist Selman Waksman, who in his lifetime discovered over 20 antibiotics.
The discovery of antibiotics in the 20th century was a major advancement in medicine. At the time of the discovery, war was taking place, which resulted in a plethora of infected wounds. Antibiotics can be described as a use, laboratory effect, or an action of a chemical compound (Clardy et al ...
In 1928 Alexander Fleming discovered penicillin, though he did not realize the full significance of his discovery for at least another decade. He eventually received the Nobel Prize in Physiology or Medicine in 1945.
Antibiotics have transformed human health by saving millions of lives and alleviating much human misery. However, in most parts of the world it’s easy to take treatment with antibiotics for granted and we tend to forget that the drugs were discovered less than a century ago.
