How Did Alexander Fleming Change The Scientific Mind

Alexander Fleming invented penicillin, but before that you could die from simple infections. Fleming was a Scottish bacteriologist First great discovery was lysosome which had no effect on the most destructive bacteria. Using his curiosity and scientific mind and despite how purifying penicillin was quite a challenge, Alexander Fleming has definitely made a change in the world’s medicine by creating penicillin, one of the world’s first antibiotics.
Since he was 20 he began in the medical field with led him to revolutionizing medicine as we know it. Alexander Fleming wanted to be in the medical field and knew what he wanted to do, but a temporary job changed his mind. “He entered the medical field in 1901, studying at St. Mary's Hospital Medical

After penicillin came the era of antibiotics and now everyone’s life span was longer. “Returning from holiday on September 3, 1928, 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, save 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.” When Fleming came back from vacation with his family he noticed mold had grown on one of the petri dishes this ending revolutionizing medicine. “The introduction of penicillin in the 1940s, which began the era of antibiotics, has been recognized as one of the greatest advances in therapeutic medicine. 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.” Penicillin made a huge advancement in medicine and the United States helped a lot with making it on a larger scale. With the discovery of penicillin later came antibiotic resistant

Bacteria is always changing and we have to keep making medicine to protect us from it. “‘For the longest time we've had a number of different antibiotics in the pipeline at any given time, so whenever we ran out of the ability to use one, we would move to the next one,’ Dr. Michael Bell, an expert in drug-resistant pathogens at the Centers for Disease Control and Prevention, told VOA. But that's no longer possible. Joe Larsen, the director of biological, chemical and radiological and nuclear countermeasures at the Department of Health and Human Services, said his department drew up a list of pathogens several years ago that were becoming resistant to antibiotics.” They have created many antibiotics and anytime one didn’t work they could use another one, but now antibiotics are becoming not as helpful and soon we could be dying from infections. As antibiotics are becoming less helpful more people are dying from infections. “Lauri Hicks, who leads research on antibiotic use and resistance trends at the CDC, said, ‘We are seeing greater than 2 million episodes of antibiotic resistant infections each year in the U.S. alone. Twenty-three thousand of these episodes result in death.’” Two million people in the United States get antibiotic resistant infections, but twenty-three thousand of them die. The invention of penicillin has kept us safe for a while, but
