Makayla Cook Ms. Barbee Honors Chemistry 5-16-14 History of Penicillin The advancement in technology has been of great benefit to society but has also contributed to the spread of diseases. The food produced is processed using chemicals which in turn make people less immune and vulnerable to developing disease. Reports indicate that there are a significant number of people in the society suffering from various diseases (Shorter and David 155). Therefore‚ scientists worked to make antibiotics

1. THE DYING SUN Q. 1: How is it that star seldom finds another star near it? Ans: A star seldom finds another star near it because there is a distance of millions of miles between the two stars. Moreover‚ space is immensely vast and each star is bound to travel in its own orbit. Q. 2: What happened when‚ according to Sir James Jeans‚ a wandering star‚ wandering through space came near the sun? Ans: When a wandering star came near the sun‚ it raised tides on the surface of the sun

bacteriologist‚ Sir Alexander Fleming‚ was tidying up his lab. After having been on vacation‚ he returned to work to find that a petri dish of Staphylococcus bacteria had been left uncovered; and he noticed that mold on the culture had killed many of the bacteria. He identified the mold as penicillium notatum‚ and upon further research found that it could kill other bacteria and could be given to small animals without ill effect. A decade later‚ Howard Florey and Ernst Chain picked up where Fleming left off

The Jarvik devices were implanted to sustain patients waiting for transplants. 2) Penicillin Penicillin was discovered accidentally by Sir Alexander Fleming in 1928 at St. Mary’s hospital in London when he forgot to clean a Petri dish before leaving on vacation. Fleming’s experimentation with the left-behind mold led him to discover its dissolving effects on the Staphylococcus aureus bacterium. Through

however in some rare but lucky cases an accident leads to a greater result. Furthermore‚ Alexander Fleming was one of the few who made a mistake that lead to a lifesaving discovery was that of penicillin‚ which he discovered. He was an extremely gifted in many medical practices; he paved the way for live-saving modern medicine and became an iconic medical figure with an immense amount of achievements. Alexander Fleming was truly an intelligent man with tremendous amount of creativity. Best known for

It could be argued that the discovery of penicillin by Alexander Fleming in 1928 might very well be one of the greatest scientific discoveries of his time. Penicillin opened up the doors to the start of antibiotics. Antibiotics are used to fight infections‚ often bacterial‚ that invade the human body. There has been countless of people saved and made healthy again by the use of antibiotics‚ namely penicillin. Fleming’s scientific breakthrough saved numerous lives during and following D-Day.

Alexander Fleming discovered penicillin in 1928 which was the first antibiotic that fights bacteria. During the 1900’s pneumonia was one of the leading killers in America prior to the discovery of penicillin. Penicillin is important as it prevents previous life-threatening infections like pneumonia‚ blood infection‚ meningitis‚ and strep throat. In addition‚ because of penicillin‚ several amputations‚ and deaths (due to infection) during the second world war decreased. Many people have benefited
