It was the birth of the first antibiotic. Fleming was not the first to notice the bacteria-killing property of Penicillium, but he was the first to study it scientifically and publish the results. In fact, Fleming had been looking for bacteria-killing substances for a number of years, ever since he had served as a medical officer in World War I and witnessed soldiers dying from bacteria-caused infections. He had already discovered one such antimicrobial agent—the chemical lysozyme—which he detected in his own tears and nasal mucus, so he knew what bacteria-killing signs to look for. If you’ve ever seen a piece of moldy bread or rotting fruit, then you’ve met the Penicillium fungus.…
These men were given standard treatment but were denied antibiotics. In 1940, researchers discovered that penicillin was an effective cure. During the 1950s, penicillin…
On 4 February 1965 Sir Howard was appointed a life peer and became Baron Florey of Adelaide in the State of South Australia and Commonwealth of Australia. This was a higher honour than the knighthood awarded to penicillin 's discoverer and it recognised the monumental work Florey did in making penicillin available in sufficient quantities to save millions of lives in the…
No doubt the pain and suffering endured by the soldiers could have been greatly reduced by its use. It was not only a miracle drug for the soldiers in battle, it also saved many lives in society. Children who received cuts and scrapes during play could now be cured in a relatively short time with this simple fungus. Often simple wounds, or even wounds received by farmers, or factory workers who were hurt on the job were often a death sentence. The discovery of penicillin changed that. Not only was penicillin great at healing wounds, it was also effective against diseases such as syphilis, strep throat, and rheumatic fever. When you consider the massive number of people whose lives have been saved, it is easy to declare that penicillin is one of the greatest discoveries of all…
Thinking he had found an enzyme more powerful than lysozyme, Fleming decided to investigate further. What he found out, though, was that it was not an enzyme at all, but an antibiotic -- one of the first antibiotics to be discovered. Further development of the substance was not a one-man operation, as his previous efforts had been, so Fleming recruited two young researchers. The three men unfortunately failed to stabilize and purify penicillin, but Fleming pointed out that penicillin had clinical potential, both in topical and injectable forms, if it could be developed properly.…
Penicillin was probably the number one most used invention of the entire war. Penicillin was invented in 1928 by Alexander Fleming but it was not used in mass production until World War II (Rosenberg, Alexander Fleming Discovers Penicillin). The war had so many casualties that it forced the mass use of penicillin to fight off the bacteria in the soldiers wounds and bodies. Without penicillin soldiers who had minor injuries may have died or suffered amputation do to infection caused by bacteria. Penicillin saved uncountable lives and limbs of soldiers during the war. Penicillin was the most important and lifesaving invention forced into use during World War II. Brian J. Ford…
In 1940 penicillin was finally produced and by this time World War II has started. Wounded soldiers were in need for penicillin, as records show penicillin has been used on D-Day to cure soldiers from gangrene. Medical companies started sending out a 100 billion units of penicillin per month by 1944. After this drug's miraculous effects on these soldiers, more and more of this drug was demanded from the medical companies in the United States. Researchers believe that penicillin was one of the indirect causes of the victory of the allies during the war. Today some of us don't realize the importance of penicillin and that it prevents many children from getting diseases such as infections of the bone, stomach, or throat. Back then children died regularly from what is today considered minor diseases and infections. Indeed penicillin is a miracle drug.…
Alexander Fleming was a German botanist, biologist, and pharmacologist who discovered the first antibiotic. He did this through a rather extraordinary happenstance. While working with the properties of the bacterium staphylococcus he left on vacation. When he got back and was cleaning out his work area he noticed that a few of the slides he’d been working on had been contaminated by fungus. Upon noting that the staphylococcus colonize bordering the fungus had died he began asking more questions. Namely what was it about the fungus that caused it to kill the bacteria?…

Life before September 1928 proved to be a difficult time for many. The quality of life across the world was poor, and humans had a considerably shorter lifespan than today. Bacterial infections ranked as a leading cause of death. These infections spread easily, and diseases such as pneumonia, syphilis, gonorrhea, diphtheria, and scarlet fever as well as wounds and childbirth infections killed thousands every year. Surgical infections were also a major killer, and doctors had no protection from any of these infections. The discovery of the first antibiotic, penicillin, in 1928 changed the lives of people forever. Penicillin provided a cure for many deadly infections, and its discovery led to the discovery of many other antibiotics, such as streptomycin, which are used to treat everyday infections for countless ailments, saving and improving lives throughout the world.…
One may argue that one of the most helpful drugs during word war two, penicillin, was discovered in 1960, prior to world war two. Although penicillin wasn’t discovered during world war two, it was improved on many levels during the time such as production on an industrial scale, it became much more readily available, and by 1945 it was 20 times stronger than the 1939 version of penicillin. Therefore, even though penicillin was developed pre world war two, it made extreme improvements since 1939. It was 20 times stronger than the 1939 version.…
Miracle cures like penicillin and other antibiotics have proven the value of research. Many illnesses and diseases are currently under heavy research. Although not much research can give results that penicillin or other antibiotics have attained does not invalidate the necessity of research and the importance of it. There exist copious treatments for diseases today previously diagnosed terminal. Today those treatments extend life that just a few years ago would have killed or disabled it.…
Alexander Fleming showed much intelligence in his early life after he was transferred to the Kilmarnock Academy. He entered the school when he was twelve years old and only stayed there for one year. Throughout his early and later education, Fleming greatly enjoyed competition with other people. He always scored at or near the top of his class and apparently without much effort. Years later, he impressively completed his medical studies in 1906 and was qualified to become a doctor during the same year. He decided to continue to his research and accepted a job at St. Mary’s as a junior assistant. He also continued his education and studied at the London University. In 1908, he earned his degrees and also received the London University Gold Medal. (“Alexander Fleming,” World of Anatomy) According to Nicholas Bakalar, Fleming was an accomplished biologist well before his famous discovery of penicillin, and his name first appeared in The New York Times on May 18, 1922, seven years before any news of the drug. Likewise, Fleming also showed intelligence through the discovery of Penicillin. In 1928, he discovered this famous antibacterial substance and was bewildered when he noticed a strange mold contaminant had inhibited the growth of the disease-causing bacteria that was grown on the plate. Later he identified the mold as Penicillium notatum, which was a very rare organism. In the World of Anatomy, it showed that he was greatly recognized sich as:…
The discovery of penicillin by Sir Alexander Fleming is believed to be one of the greatest gifts every made to humankind. This discovery introduced the era of antibiotics to the world (Calvo, 2000). Staphylococcus aureus causes various pus-forming infections such as boils, styes, pneumonia, urinary tract infections, and more seriously osteomyelitis and endocarditis (Todar, PhD, 2008). The recurring theme of Sir Fleming’s career was to find a chemical substance that would kill infections bacteria without killing surrounding tissue (“Sir Alexander Fleming,” 2004).…
The history of drug discovery in the pharmaceutical industry and academic labs over the past half-century shows a progression of discovery paradigms that began shortly after “miracle drugs” such as the penicillins became available to the public after World War…
