@newdlenews: The first broadly effective antibiotic began with a contaminated petri dish that someone forgot to clean up. On Sept. 28, Alexander Fleming returned from vacation to his lab at St. Mary's Hospital in London. He found that a dish of Staphylococcus bacteria had been overtaken by mold. He noticed that the bacteria around the mold had been destroyed, leaving a clear zone where they couldn't grow. The culprit was a Penicillium strain, that marked the launch of the world's first broadly effective antibiotic, changing modern medicine.
