    Leewenhoek
  7. ____ found that if flies were prevented from landing on meat maggots did not appear.
    Redi
  8. Why was Redi's experiments not readily accepted?
    B/c it was believed that the gauze covering the top of the jar kept out the "vital life force"
  9. How did Pasteur discredit the "vital life force" BS?
    By utilizing swan neck flasks that allowed in the vital life force but kept microorganisms fr reaching the medium
  10. The study of the source, cause & mode of transmission of disease is known as ____.
    Epidemiology
  11. The belief that disease came fr altered chem quality of the atmosphere or fr tiny poisonous particles of decompose matter is known as ____.
    Miasma
  12. What was the "Most Unspeakable Terror" & who's idea was it?
    Semmelweis was shocked by how many women were dying during child birth
  13. What did Semmelweis attribute the "Most Unspeakable Terror" too?
    Students working with cadavers & not washing their hands prior to delivering a child
  14. Snow worked with what disease & how did he mitigate the problem?
    • Cholera in London
    • He removed the handles on the drinking water pumps in the street in disease ridden areas
  15. What did Snow determine about the spread of cholera?
    It was spreading via "organized particles" in water NOT miasma
  16. The term used to describe a method to create resistance to a material by inoculating w/pathogenic material is what?

    Microorganisms that cause disease
  26. ___ ___ proposed surgical infections are result of living organisms in air.
    Joseph Lister
  27. How did Joseph Lister prevent infection in surgical sites?
    By spraying carbolic acid in wounds greatly decreasing infection
