Microbiology Chapter 1
Who was one of the early natural philosophers who coined the name “cella” for the empty cork spaces that became the word we use today, “cells”?
Robert Hooke
Leeuwenhoek made lenses that allowed him to magnify objects more than 200X. However, he failed to promote scientific inquiry because
he didn't reveal how he ground the lenses and no one else was doing it that well.
Leeuwenhoek was the first person to
describe bacteria.
Francesco Redi is famous for performing one of the first experiments over the debate regarding spontaneous generation. What was his experiment?
He covered some jars of meat with gauze and left others open. The covered jars did not develop maggots, the uncovered ones did.
________ did not attempt to prove or refute the idea of spontaneous generation.
Robert Koch
Which one of the following would be consistent with the idea of spontaneous generation?
Sick people give rise to microorganisms in their body.
Spallanzani’s experiments showed that
experiments can be modified to test a hypothesis.
Which pair of scientists were antagonists during the same period of history?
Spallanzani and Needham
Semmelweis showed that the transmission of disease could be interrupted by
washing hands in chlorine water.
In 1854, John Snow determined that contaminated water transmits
cholera.
John Snow traced the source of an 1854 outbreak of cholera to
a contaminated municipal water supply.
He was a surgeon who observed cowpox could provide immunity for smallpox.
What was Christian Ehrenberg responsible for naming in the 1830's?
He gave the name "bacteria".
The classical Golden Age of microbiology came to an end partly due to the
the advent of World War I.
Pasteur’s study of fermentation was critical to the development of microbiology because
it showed that microorganisms bring about chemical changes.
Pasteur’s studies proved that grape juice was a fermentation product of
yeasts.
Pasteur first suggested that bacteria could cause disease in humans by showing that bacteria could
sour wine.
Pasteur’s observations that protozoa were related to the silkworm disease strengthened his belief in the
germ theory of disease.
Lister used __________ to clean wounds and surgical instruments.
carbolic acid
Koch’s postulates provided guidelines for
relating certain microorganisms with certain diseases.
Koch was responsible for thorough observations on the organisms of
tuberculosis and anthrax.
Pasteur was able to prepare a vaccine against rabies even though
he was unable to see the organism.
Which coworker of Koch's demonstrated that diphtheria could be treated with an antitoxin?
von Behring.
The accomplishments of Koch include all the following except
development of the rabies vaccine.
Which scientists showed diphtheria was caused by a bacterial toxin?
Roux and Yersin
. Studies during the classical Golden Age included all the following diseases except
measles
Which scientists worked independently to show the infectious nature of the tobacco mosaic virus?
Ivanowsky and Beijerinck.
Two of the earliest environmental microbiologists were
Winogradsky and Beijerinck.
All of the following are examples of new emerging infectious diseases except
chickenpox.
The bacillus, coccus, and spirillum shapes are typical of the
bacteria.
Movement by flagella, cilia, or a crawling movement is typical of the
protozoa.
In 1943 Luria and Dulbrück used ______________ to show that mutations can arise spontaneously.
Escherichia coli
Beadle and Tatum used the fungus Neurospora to show that
one gene codes for one enzyme.
Hershey and Chase proved that
DNA is the genetic material of cells.
. Which of the following types of cells are Prokaryotes?
bacteria
The “magic bullet” of Paul Ehrlich was
a chemical used to treat syphilis.
Penicillin was discovered by
Fleming.
The antibiotic penicillin is produced by
a fungus.
What makes this the third golden age of microbiology?
The use of biotechnology to manipulate microbes for our benefit
There are three golden ages of microbiology listed in your text. Which of the following statements regarding them is true?
The rise in antibiotic resistance is due, in part, to
all of the above are correct.
Which of the following are examples of bioterrorism?
the intentional use of biological agents to create fear or inflict disease or death on a large population
. Which one of the following statements is true concerning biofilms?
A and B are correct.
Which one of the following is not a role for bioremediation?
Curing infectious diseases.
