MIC205A- Exam 1 UPDATED
QUESTIONS AND CORRECT ANSWERS
Types of Microbes - CORRECT ANSWER 1. bacteria (2 nm)
2. fungi (20 nm)
3. protozoa (50 nm)
4. archaea
5. microscopic algae
6. viruses
7. multicellular parasites
Elements of Nomenclature - CORRECT ANSWER -name is italicized or underlined
1. Genus: capitalized
2. Species epithet: lowercase
Robert Hooke - CORRECT ANSWER -"little boxes"
-observed cells for the first time in 1665 with crude microscope
Van Leeuwenhoek - CORRECT ANSWER -"animalcules"
-observed rain water, own feces & material scraped from teeth in late 1600s
Spontaneous Generation - CORRECT ANSWER -originally explained origin of tiny living
things
-hypothetical process in which some forms of life can spontaneously arise from nonliving matter
Francesco Redi - CORRECT ANSWER -tried, but failed, to disprove spontaneous generation
-gauze covered jar with meat did not contain maggots
Biogenesis - CORRECT ANSWER claim that living cells can only arise from preexisting
living cells
, Louis Pasteur - CORRECT ANSWER -French scientist
-provided evidence against spontaneous generation (boiled broth, swan-neck container)
-contributions: microorganisms can be present in nonliving matter & microbial life can be destroyed
by heat
Aseptic techniques - CORRECT ANSWER -basis formed by Louis Pasteur
-techniques that prevent contamination by unwanted microorganisms
-standard practice in lab/medical procedures
-1st & most important thing to learn as microbiologist
Pasteurization - CORRECT ANSWER -process of heating a liquid (milk, wine, beer) just
enough to kill most of the bacteria that cause spoilage
The Golden Age of Microbiology - CORRECT ANSWER -1857-1914
-included Germ Theory, Joseph Lister, Ignaz Semmelweiss, Robert Koch
Germ Theory - CORRECT ANSWER -theory that microorganisms cause disease (not
punishment, demons, or vapors)
Joseph Lister - CORRECT ANSWER -English surgeon
-applied Germ Theory to medical procedures
-used phenol (carbolic acid) to kill bacteria, dramatically reduced infection & death
Ignaz Semmelweiss - CORRECT ANSWER -Hungarian physician
-demonstrated doctors didn't disinfect their hands & transmitted infectious diseases between obstetric
patients (high rate of puerperal fever in some women)
Robert Koch - CORRECT ANSWER -young rival to Louis Pasteur
-race to discover cause of Anthrax
-discovered rod-shaped bacteria Bacillus anthracis in blood of cattle that died from Anthrax
