Almost a century ago Scottish scientist Alexander Fleming discovered mould in one of his petri dishes had killed the Staphylococci bacteria he was growing. He spent the next 10 years growing the penicillium mould whilst trying to isolate the antibiotic it secreted. Ten years later Australian scientist Howard Florey & German-born British biochemist Ernst Cain purified & concentrated the compound, transforming penicillin into a lifesaver, Fleming, Florey & Chain receive the Nobel Prize for Medicine in 1945. In 1894 Perth-based Professors Barry Marshall & Robin Warren discovered that the bacterium Helicobacter pylori (H.pylori) is the cause of stomach ulcers. Marshall was so sure he was right about the cause of stomach ulcers that he swallowed bacteria to prove his point,(medical doctrine previously hold that stomach ulcers were caused by stress). A week later, after developing all the symptoms of gastritis he took antibiotics & the symptoms cleared. Marshall & Warren were awarded the Nobel Prize in Medicine in 2005.
