MCB 2610 Exam #1
Robert Hooke (1665) - correct answer ✔- developed microscope that could
magnify 30X
-cell theory: all living things are composed of cells ( life consisted of "little
boxes")
Antony van Leeuwenhoek (1632-1723) - correct answer ✔-first person to
observe and describe microorganisms accurately with a microscope that could
magnify 50-300X
-microbes = animalcules
-studied own teeth scrapings and diarrhea
spontaneous generation - correct answer ✔living organisms can develop
from nonliving or decomposing matter
Redi - correct answer ✔-wanted to discredit spontaneous generation
-experiment: 3 containers with meat, one sealed, one covered with gauze, and
one open
-showed that maggots on decaying meat came from fly eggs
Needham (1713-1781) - correct answer ✔experiment used mutton broth in
flasks that was boiled and seal. Resulted in the broth becoming cloudy and
contained microorganisms
Spallanzani (1729-1799) - correct answer ✔experiment used broth in flasks
that he sealed then boiled. Resulted in no growth of microorganisms
, Luis Pasteur (1822-1895) - correct answer ✔-experiment: placed nutrient
solution in swan-neck flasks and boiled the solutions, leaving them exposed to
air
-no growth of microorganisms in the flasks, but contaminated dust collected in
the curve. when the dust was added, then the broth grew microorganisms
-saved the wine industry
Tyndall (1820-1893) - correct answer ✔-demonstrated that dust carries
microorganisms
-provided evidence for the existence of exceptionally heat-resistant forms of
bacteria
Cohn (1828-1898) - correct answer ✔discovered heat resistant bacteria
could produce endospores
Semmelweis (1840's) - correct answer ✔-"savior of mothers"
-found out that having the med students wash their hands before delivering a
baby reduced the risk of death
Lister (1827-1912) - correct answer ✔-"Father of Modern Surgery"
-provided indirect evidence that microorganisms were the cause of disease
-developed a system of surgery design to prevent microorganisms from
entering wounds, methods for treating instruments and surgical dressing using
phenol
Snow (1854 Cholera outbreak) - correct answer ✔-first epidemiologist
-mapped affected areas, discovered that a sewer pipe was leaking into a
popular well that spread the disease, removed the pump handle himself to
save lives
