    • Penicillin
      • Alexander Fleming
        • Reasons why he was important
          • Discovered an antibiotic and magic bullet
          • Found a cure for staphylococci
          • Rediscovered the fact that mould could kill germs
          • Wrote a report in 1929
          • tested and found it could kill bacteria
          • Killed lethal bacteria
          • Found it could be put on a wound
          • Grew pure samples of mould
          • Used instead antiseptics
        • Reasons why he wasn't important
          • He wasn't the first to discover it (Sanderson)
          • Didn't have enough resources to further the discovery
          • Other factors had helped him
          • Couldn't extract it and didn't know how to purify it
        • In1928 rediscovered the properties of penicillin
      • Florey and Chain
        • In the 1930s became interested in Flemings report and so they decided to put a research team together and with government funding they would be able to purify and extract it
        • Used the recent freeze drying method to extract pure penicillin
        • Tested it on mice first and the tested mice survived from the streptococci bacteria
        • Tested it on a human, but the patient died due to a lack of penicillin
      • Factors that helped
        • Previous knowledge - F+C used Flemings knowledge
        • War - countries were more inclined to develop penicillin as they were desperate
        • Research teams - large French research team
        • Government funding - US government gave $80 million to 4 drug companies
        • Industry - mass produced penicillin
        • Key individuals
        • Technology - freeze drying technology used to refine penicillin
    • antibiotic - a drug made from bacteria to kill other bacteria
