drug was discovered in a very unusual way by Alexander Fleming in 1920. Fleming had returned from a summer vacation and began sorting petri dishes‚ which contained colonies. Which are collections of organism growth. The colonies were that of Staphylococcus; which is a bacterium that causes boils‚ some throat and abscesses. He noticed in the petri dishes that they contained a blob of mold that was growing. Soon after further review it was said that the areas right around the mold was Penicillium
