Sir Alexander Fleming was born in Lochfield, Scotland, on August 6, 1881. He was the third of four siblings, and he also had four half-brothers, he attended Loudoun Moor School and Darvel School. Furthermore, for 2 years, he attended school at Kilmarnock Academy.

After working in a shipping service office for 4 years, Fleming, who was 20 years old at that time, inherited some of the assets from his uncle. Fleming’s brother, who was a doctor at the time, suggested that his brother follow in his career. Hence, in 1901, Fleming enrolled in St. Hospital. Mary’s, London. Then, he got a special qualification to go to school in 1906 with the choice to become a surgeon. Starting from his job, Fleming became a Scottish scientist who managed to find penicillin, which is a type of antibiotic produced by the fungus Penicillium notatum. This discovery substance can be used to kill various types of bacteria that are harmful to the human body.

Penicillin was discovered by Fleming after he graduated from St. Hospital School of Medicine. Mary in London. Furthermore, he deepened his knowledge in the field of investigation of immunity.

As an army doctor in World War I, Fleming learned about infections in wounds. At that time, he found that there are various antiseptics that can damage body cells faster than fighting the actual disease. He realized that something he needed was another material that could kill bacteria, but not damage and be harmful to the cells of the human body.

In fact, Fleming is a very clever research expert. Unfortunately, he was among the careless. Therefore, the laboratory often looks messy.

In 1928, after returning from a long vacation, Fleming remembered the Staphylococcus bacteria in a dish in the laboratory, which was left open in the air. As a result, the bacteria become dirty and rot because it is not stored properly. Apparently, these bacteria have been contaminated by a type of fungus. Some plates in the laboratory containing bacteria are discarded. However, Fleming noticed that the development of bacteria in the area contaminated by the fungus was hampered. Fleming took a sample of the fungus, then examined it. He found that the fungus was from the genus Penicillium. This is what underlies the drug is called penicillin or penicillin.

Fleming’s findings were broadcast to a wide audience in 1929. However, at first, the findings did not attract the attention of many people. Furthermore, he suggested that penicillin plays an important role in treatment. His discovery in September 1928 marked the new century in the world of modern antibiotics.

Fleming also found that bacteria could develop resistance and resistance to penicillin if penicillin used as an antibiotic was too little and was used for a short period of time. However, because he was unable to develop techniques for purifying penicillin, more than 10 years had passed, the important drug was abandoned.

Finally, in the late 1930s, two investigators in the field of British medicine, Howard Walter Florey and Ernst Boris Chain, discovered Fleming’s writing. They review Fleming’s work, then refine it and write down the results of their studies.

Next, they purify penicillin, then test the substance in the animal laboratory. In 1941, they tested penicillin in humans who were sick. Their experiments clearly prove that this new drug has amazing potential.

When the war was over in 1945, the use of penicillin had spread throughout the world. The discovery of penicillin is very evocative of the investigation in other fields of antibiotics. And, subsequent investigations have led to various “miracle cures.” However, penicillin remains the most widely used antibiotic by the public.

One of the factors that makes penicillin widely used in the medical field is that penicillin is proven effective against various types of harmful microorganisms. This drug is useful for healing syphilis, gonorrhea, diphtheria, various arthritis, bronchitis, scarlet, liver, gangrene, and others.

Since penicillin has saved millions of lives, and certainly will save even more lives in the future, very few people doubt the important role of penicillin for treatment.

After Fleming announces his findings, sooner or later there will be an improvement to his invention. And, penicillin will also be produced purer.

Some time later, Fleming married and lived happily with a child. In 1945, he won the Nobel Prize for his discovery services (penicillin). And, he died of a heart attack on March 11, 1955 at the age of 73 years. Finally, his body was buried in the Cathedral of St. Paul, London.
