    Study Notes

    Britain's Health Revolution (1000-Present)

    • Germ theory developed from Pasteur and Koch's discoveries
    • Early theories of disease (pre-1800s) often attributed illness to factors such as miasma (bad air) or spontaneous generation
    • 1677: First basic microscope allowed scientists to see moving microorganisms
    • 1699 : Francesco Redi experimented, showing some organisms came from external sources
    • 1748 : John Needham contradicted Redi, experiments highlighted the importance of clean equipment
    • 18th century : Spontaneous generation was a prevalent belief
    • Louis Pasteur challenged spontaneous generation (1857-1860)
      • Examined wine and beer souring, demonstrating microbial involvement
      • Swan-necked flask experiment : microbes enter from the air, not spontaneous generation
      • Showed bacteria not spontaneously created; biological process
    • Robert Koch built on Pasteur's work, establishing germ theory
      • Found bacteria specifically related to disease, like anthrax
      • Demonstrated cause-and-effect relationship between specific germs and specific diseases, such as cholera and tuberculosis (TB)
    • Early opposition to Germ Theory
      • Charlton Bastian was a leading surgeon, with strong arguments against germ theory; also a respected public speaker
      • Scientific community still held differing views even after substantial evidence emerged
    • Development of vaccines:
      • Pasteur applied Koch's germ research to illness
      • Worked on chicken cholera and rabies, creating vaccines
    • Acceptance and impact of germ theory
      • Tyndall : further promoted Pasteur's findings
      • Tyndall and Koch's investigations helped accept germ theory in Britain
      • Research by British doctors between 1873-1875 further supported the germ theory
      • Roberts and Cheyne explained the theory's impact, making it readily understood

    Magic Bullets (Chemical Cures)

    • Paul Ehrlich's discovery of Salversan 606: a compound that killed syphilis bacteria without harming humans
    • Increased research led to developing treatments and understanding disease.
