MICR 290 Lecture Quiz #1 (Ch. 1-6) EXAM QUESTIONS
WITH CORRECT ANSWERS
Who |were |the |fathers |of |microbiology |and |what |did |they |do? |- |CORRECT |ANSWER✔✔--Antoni
|van |Leeuwenhoek |(dutch): |first |to |make/use |simple |microbes |to |discover |bacteria |
-Robert |Koch: |causative |agents |of |disease |and |examined |colonies |of |microorganisms |(Anthrax: |
first |disease |proven |to |be |bacterial)
-Carolus |Linnaeus: |Created |taxonomic |system |(grouping |similar |organisms |together |--> |
eukaryotes |and |protozoa)
What |are |Koch's |postulates? |- |CORRECT |ANSWER✔✔-1. |microorganism |must |be |found |in |
abundance |in |all |organisms |suffering |from |disease
2. |microorganism |must |be |isolated |from |diseased |organism |and |grown |in |pure |culture |
3. |cultured |microorganism |should |cause |disease |when |introduced |into |healthy |organism
4. |microorganism |must |be |reisolated |from |the |inoculated, |diseased |experimental |host |and |
identified |as |being |identical |to |the |original |specific |causative |agent
Leeuwenhoek's |micoorganisms |grouped |into |Linnaeus' |6 |categories: |- |CORRECT |ANSWER✔✔--
Prokaryotes: |bacteria, |archaea, |fungi |
-Eukaryotes: |protozoa, |algae/plants, |small |multicellular |animals
, What |does |pathogenic |mean? |- |CORRECT |ANSWER✔✔-Causes |disease
Protozoa |- |CORRECT |ANSWER✔✔--single-celled |eukaryotes |
-similar |to |animals |in |their |nutritional |needs |and |cellular |structure
What |does |virus |(bacteriophage) |do? |- |CORRECT |ANSWER✔✔-Injects |its |DNA |to |make |more |
viruses
What |did |Aristotle |propose? |- |CORRECT |ANSWER✔✔-Spontaneous |generation: |living |things |
can |arise |from |nonliving |matter
Pasteur's |experiments |with |"swan |necked" |flasks |- |CORRECT |ANSWER✔✔-1. |infusion |is |heated
|(steam |escapes |from |open |end |of |flask)
2.infusion |sits; |no |microbes |appear |
(air |moves |in |and |out |of |flask) |- |(months |pass)
3. |infusion |remains |sterile |indefinitely |
(dust |from |air |settles |in |bend)
How |can |we |prevent |infection |and |disease? |- |CORRECT |ANSWER✔✔--Semmelweis |and |hand |
washing |(disease |puerperal |fever)
-Lister's |antiseptic |technique
-Nightingale |and |nursing
Prokaryotes |vs. |Eukaryotes |- |CORRECT |ANSWER✔✔--Prokaryotes: |lack |nucleus |and |membrane
|bound |organelles, |small, |simple |structure, |binary |fission |
