929flemingAlexander Fleming publishes the first paper describing penicillin and its effect on gram-positive microorganisms. This finding is unique since it is a rare example of bacterial lysis and not just microbial antagonism brought on by the mold Penicillium. Fleming kept his cultures 2-3 weeks before discarding them. When he looked at one set he noticed that the bacteria seemed to be dissolving and the mold was contaminating the culture. When penicillin is finally produced in major quantities in the 1940s, its power and availability effectively launch the “Antibiotics Era,” a major revolution in public health and medicine Buy Levitra. With Florey and Chain, Fleming is awarded the Nobel Prize in Medicine or Physiology in 1945.
