A Short History of Penicillin

A search worldwide began for the perfect strain of penicillin mold that would produce the largest amount of the mold when it was grown in a vat containing corn steep liquor and strangely, it was not found abroad, but right at home in Peoria in a market next to the lab assisting Oxford with the production of the mold.
By almost the end of 1941, Andrew J. Moyer, a mold nutrition expert, succeeded in multiplying the penicillin production by 10 times and by the year 1943, the clinical trials needed to approve the penicillin doses for public use. These doses were extremely expensive in the year 1940, but as time went on, they became much less costly, being around $20 a dose in July of 1943, and around fifty cents per dose in 1946.
About four years after penicillin had begun being produced on a large scale in 1943, bacteria and other microbes started resisting it. Staphylococcus aureus was one of the first to effectively battle penicillin and while it is a normal, mostly harmless inhabitant of the human body, it can cause pneumonia or TSS (toxic shock syndrome, associated with the use of tampons) when it begins to multiply in large numbers. It then begins to produce a toxin and this is what makes the person ill.
