WESTCOTT MICROBIOLOGY FINAL EXAM
180 Practice Questions with Answers & Rationales
SECTION 1: HISTORY & FOUNDATIONS OF MICROBIOLOGY (Questions
1-20)
Question 1
Who is considered the "father of Western medicine"?
A) Marcus Terentius Varro
B) Thucydides
C) Antonie van Leeuwenhoek
D) Hippocrates
Answer: D) Hippocrates
Rationale: Hippocrates is recognized as the father of Western medicine
for his contributions to medical ethics and his belief that disease had
natural, not supernatural, causes. While Varro proposed that swamps
harbor disease-causing agents and Leeuwenhoek first observed
microorganisms, Hippocrates established medicine as a discipline
separate from philosophy and religion .
,Question 2
Who was the first to observe "animalcules" under the microscope?
A) Antonie van Leeuwenhoek
B) Ötzi the Iceman
C) Marcus Terentius Varro
D) Robert Koch
Answer: A) Antonie van Leeuwenhoek
Rationale: Antonie van Leeuwenhoek, using a simple but powerful
microscope he crafted himself, was the first to observe and describe
single-celled organisms, which he called "animalcules," in 1675. His
observations marked the beginning of microbiology as a science .
Question 3
Who proposed that swamps might harbor tiny, disease-causing animals
too small to see?
,A) Thucydides
B) Marcus Terentius Varro
C) Hippocrates
D) Louis Pasteur
Answer: B) Marcus Terentius Varro
Rationale: Marcus Terentius Varro, a Roman scholar, proposed the
concept that swamps might harbor tiny, invisible animals that could
enter the body through the nose and mouth and cause disease. This
was an early theory of contagion long before microorganisms were
actually observed .
Question 4
Which of the following foods is NOT made by fermentation?
A) Beer
B) Bread
C) Cheese
D) Orange juice
, Answer: D) Orange juice
Rationale: Beer, bread, and cheese are all products of microbial
fermentation. Beer is produced by yeast fermenting sugars, bread by
yeast producing CO₂ for leavening, and cheese by bacterial
fermentation of milk. Orange juice is simply pressed from fruit and does
not involve fermentation .
Question 5
Which scientist's experiments with swan-neck flasks finally disproved
spontaneous generation?
A) Francesco Redi
B) Lazzaro Spallanzani
C) Louis Pasteur
D) John Needham
Answer: C) Louis Pasteur
