What did Alexander Fleming discover?

Alexander Fleming was born in 7^th August,1881 AD in Scotland. He invented Penicillin which can fight against the communicable diseases and control them. He has obtained medical degree from Saint Marry School in 1906 AD. After that he started to research on antibiotics. He also joined in army medical campus and work till first world war ends. After end of first world war in 1918 AD, he returned to Saint Marry school. One day in his laboratory he was using one petri dish for collecting sample in his experiment. He saw a surprising things while observing the microbes inside the mucous membrane collected from pox diseases. He saw that lot of mucor growing inside petri dish jelly and the microbes were all dead. Those mucor cames from air and grow inside the petri dishes. So, Alexander Fleming start to search new things called Penicillin notadum. This was very rare kinds of matters. Fleming goes on many repeated experiment about the mucor. He became successful to grow the sample of rare Penicillin. After that he collect the juice from those mucor Penicillin and studied it’s effect on microbes. He repeated his testing on other different types of harmful microbes. He found that those juices obtained from Penicillin mu cor were very poisonous for microbes and those microbes can be killed by this penicillin juices. He found that while abstracting the penicillin for uses in human body, it reacts rapidly and became useless. Alexander Fleming continues his research on it and discovered its solution. In 1941 AD during the second world war, this medicine was tested on six patients. This medicines shows very good results on them. Since unluckily there were only few dosses of penicillin, so many patients loose their lives. After that Alexander Fleming tried to abstract penicillin as much as possible to meet the demand of patients. In the last day of 1941 AD, Fleming goes to America. He discuss with many scientist about the method of abstracting the penicillin. American medical industries support Fleming in his works. After several days of continue researches and experiment, they found the correct method to abstract the penicillin in large volume. After that medicines were manufactured from penicillin. This penicillin were widely used in many medicines and became the backbone of medical world. Before surgical operation, doctor used to inject penicillin which keep the patient safe from different bacterial infections. After the invention of penicillin, other different types of antibiotic medicines were invented. Nowadays those medicines are protecting millions of people suffering from different diseases. From this great work Alexander Fleming received the Nobel prize in medical field in 1945 AD. He became world famous from his discovery. He died in 11 March 1955 AD.
