Penicillin test

In 1940, in one of the most famous animal tests in medical history, eight mice were inoculated with a lethal dose of streptococci and then four of them were injected with penicillin. Next day the four mice given streptococci alone were dead, the four with penicillin were healthy. Oxford scientists Howard Florey, Ernst Chain and Norman Heatley had revived Alexander Fleming's work. They produced enough antibiotic to test by isolating the active ingredient from what Fleming had called “mould juice,” Ten years before, Fleming's interest had waned when he found penicillin production to be difficult, that it was very unstable, had no effect on certain bacteria (cholera, bubonic plague) and didn't work in animals when given by mouth.«
