Penicillins have played a study role in treating pneumonia, rheumatic fever, scarlet fever, and many different diseases. The development of penicillin had a tremendous impact on medical specialty and encouraged research that lead to the discovery of many another(prenominal) antibiotics.(Johnson, 1991) The improbable chain of events that led Alexander Fleming to discover penicillin in 1928 is the stuff of which scientific myths are made. Fleming, a young sparing research scientist with a profitable side practice treating the lues infections of prominent London artists, was pursuing his pet theory ? that his feature nasal mucus had antibacterial effects ? when he left a gloss plate smeared with Staphylococcus bacteria on his lab bench while he went on a two-week holiday.(Ho, 2003) When he returned, he noticed a clear closed chain surround the yellow-green harvest of a persuade that had by chance contaminated the plate.

Unknown to him, a spore of a rare random variable called Penicillium notatum had drifted in from a mycology lab one foundation below. Luck would have it that Fleming had decided not to store his culture in a warm incubator, and that London was then pee-pee to by a cold spell, giving the mold a chance to grow. Later, as the temperature rose, the Staphylococcus bacteria grew like a lawn, covering the entire plate ? except for the area surrounding the moldy contaminant. Seeing that halo was Flemings Eureka moment, an instant of groovy personal insight and deductive reasoning. He correctly deduced that the mold must have released a substance that inhibited the growth of the bacteria.(Ho, 2003) It was a discovery that would change the course of history. The active...
