Acacia Dairsow Page one P.5 The Amazing Discovery of Penicillin and Antibiotics! Antibiotics have been around for years, but at the same time only for a short period, as in about 80 years ago Therefore penicillin and antibiotics are one of the greatest discoveries of the 20th century Seeing as how Penicillin is one of the greatest discoveries of the 20th century, it is now commonly used to cure “common” or “simple” infections, Alexander Fleming was the one to discover Penicillin and its uses, and Penicillin was actually discovered by accident. I’ve used a variety of sources to learn and study about one

In 1928, Alexander Fleming discovered that the mold penicillium notatum could be used as an antibiotic. It was not until 1940 that penicillin was derived from the mold to be used to treat disease and sickness. Norman G. Heatley asked a team of scientist to begin working on isolating the ingredient penicillin from the mold itself. In March of 1940, the team withdrew acidified culture

The development of penicillin provided a major stepping stone for the practice of medicine, and has saved the lives of countless individuals since its synthesis.

In this reading there was many very interesting facts about penicillin. Penicillin was a breakthrough in the medical field in the 20th century. The scientist Alexander Fleming had accidentally spilled a vile of bacteria on to a plate of bacteria to his benefit he found that is had stopped the growth of bacteria. This accidental discover has benefited everyone in the world because we have to get these shots if we are infected, plus it saved many life’s in world war II. However, Penicillin is considered an antibiotic chemical that is created by living organism to stop the growth of bacteria and prevent an illness if people were to come into contact with this problem. Since the discovery and massive stock piling of this cure it has become less

Penicillin is a type of antibiotics. It fights nasty bacteria in a human body. Penicillin is used to help many different infections caused by bacteria. Penicillin was made for the soldiers in world war one, it was to help bullet wound infections and infections caused by lost limbs. Penicillin is made from extracting it from mould.

Fleming in 1928. Penicillin helped to treat some common infections: step throat, boils, it would heal wounds quicker, as well as treat more serious infections such as meningitis and pneumonia. Antibiotics usually kill only weak bacteria and after some years of antibiotic usage stronger bacteria have not only survived but also became resistant to the old cure. “Doctors have started to prescribe antibiotics to cure conditions such as ear infections, sinusitis, bronchitis, non-specific upper respiratory tract infections and even common colds and flu… According to the Director of Antimicrobial Resistance, Dr. Richard Besser, each year US physicians write $50 million worth of prescriptions that are ineffectual and unnecessary.” (Elisa Bussey). The more doctors were prescribing antibiotics, the bigger the number of people who become resistant to them. Most of the European countries prescribe antibiotics to kill bacteria only in cases of life threatening conditions. Patients in the US have become accustomed to receiving antibiotics for almost any health concerns and with time, patients have started to expect such prescriptions as a norm.

The discovery of penicillin was one of the most important discoveries in the 1900s and marks a turning point in human history. Penicillin was one of the world’s first antibiotics which eventually evolved into modern antibiotics that are used today; it has often been described as a miracle drug. The discovery of penicillin meant that doctors finally could completely cure their patients of deadly diseases. After World War I, many soldiers died from infected wounds because the antiseptics used, killed the patients’ immunological defences more than they killed the invading bacteria. Penicillin kills bacteria by destroying the cell wall of the microorganism causing the cell to burst; it was very effective in clearing bacteria without harming the

The wonderful discovery of Penicillin, a medicine that was discovered in 1928. This medicine was used to cure bacteria in humans. Penicillin had good results not only in the 1928, as it also still is very successful today. Penicillin had a big impact, it cured many people in the U.S. during World War II. penicillin,leads to the development of others antibiotics.

In 1929 Fleming published his findings to a British Journal of Experimental Pathology, referencing that penicillin had potential of therapeutic benefits. Dr. Fleming was never able to purify his samples of penicillin, but he became the first person to publish the news of its germ-killing power. Howard Florey, Ernst Chain and Norman Heatley expanded on Fleming 's work in 1938, at Oxford University.

by Dr. Alexander Fleming. As test continued, Fleming began to realize that he was on the verge of a great discovery. However, he still did not know the identity of the fungus, and had little knowledge of fungi. His crude extracts could be diluted 1,000 times and still be effective in killing bacteria. After years of working on penicillin and going nowhere, many of his co-workers grew tired of hearing about it. The first real test for penicillin came when a 48-year-old police officer nicked himself shaving. After a time, Alexander's face became infected and he developed a temperature. When he was rushed to the hospital, the doctors believed that he had only hours

Penicillin is an antibiotic used in fighting infections. A Scottish scientist named Alexander Fleming discovered penicillin in 1928. One of the first examples of the power

Fleming did not have enough of this “miracle drug” to test, so it was dismissed. After ten years, Oxford University scientists discovered Fleming's work. They used the remarkable powers of penicillin the Oxford scientist brought the drug to America to be mass-produced. Atabrine was a yellow pill shaped medical drug discovered in the 1930’s was used to treat and cure malaria. Other World War Two innovation and inventions were morphine and plasma.

Fleming began to sort through petri dishes containing colonies of Staphylococcus, bacteria that cause boils, sore throats and abscesses. He noticed something unusual on one dish. It was dotted with colonies, except for one area where a blob of mold was growing. The zone immediately around the mold—later identified as a rare strain of Penicillium notatum—was clear, as if the mold had secreted something that inhibited bacterial growth (American Chemical Society). The first introduction of penicillin began in the 1940’s, it was recognized as one of the greatest advances in therapeutic medicine. The discovery was made in the United Kingdom but because of World War II, the United States developed a large production of the drug. By 1937, an important pain killer known as methadone was introduced. Morphine, the most active substance in opium, is a very powerful painkiller that hooked many US Civil War soldiers (Drug Free World). They were wanting to find a painkiller that was less addictive to use for surgery and that’s why they invented

World War II was a historical turning point not only for the basis of political power and war tactics, but also for drugs and medical advances. Between 1939 and 1945, new medical techniques were developed as a direct response to new weaponry. One of the more profound advances was penicillin, discovered in 1928 by Scottish scientist Sir Alexander Fleming. During the war, the drug helped reduce the overall number of amputations and

Penicillin has been used by many people of it was discovered in 1928 and saved many lives in World War II. There are stories on how this substance was discovered different scientists. Penicillin has continued to forestall infectious diseases ever since it had saved thousands of lives. It was accidentally discovered by bacteriologist Alexander Fleming. It is said that it was originally found by Ernest Duchesne.
