Questions with correct Answers
Identify the scientist who is credited with the invention of the first microscope.
What did he observe?
How did these observations contribute to the early development of microbiology? - ANSW-Van
Leeuwhenhoek
He observed animacules (microorganisms)
He created high quality and powered lenses
Explain the term "aseptic technique" (sterile technique).
What are the meanings of "a" and "sept"? - ANSW-Aseptic technique is a technique used to transfer
microorganisms without contamination
"a" "sept" means without free from bacteria
Explain the theory of biogenesis.
Name the scientist who initiated the idea of biogenesis. - ANSW-Biogenesis is a theory that states that
all living cells must come from preexisting cells
Virchow established this
The debate between spontaneous generation and biogenesis took place over the course of 200 years
involving the following men. Identify which of the following sided with each theory: Needham, Pasteur,
Virchow, Spallanzani, Redi and most of the scientists of the day. - ANSW-Needham - Spontaneous
generation true of microbes
Pasteur - Biogenesis is true
Spallanzani - Spontaneous generation false of microbes
Redi: pro spontagneous gen for microbes
Explain, in detail and in order, how spontaneous generation was disproven and each scientist who
contributed in the process. How did the verification of biogenesis affect early interest in the study of
microbiology? - ANSW-Redi disproved spontaneous generation for large organisms... meat in beakers..
one covered with gauze..
Needham boiled gravy, sealed vial. let it set.. and concluded spontaneous generation was true of
microbes
Spallanzani tightly sealed boiled gravy, and concluded that spontaneous generation was false of
microbes
Virchow established biogenesis
, Pasteur boiled gravy with S shaped beaker.. let gravy set and found no microbes... proved biogenesis is
true
Explain the Germ Theory of Disease. Why was this difficult concept for people to accept? Two scientists,
Pasteur and Koch, had a part in developing the ideas behind this theory. Which of these actually proved
the Germ Theory of Disease? - ANSW-The Germ Theory of Disease states that microbes cause disease.
Koch proved this to be true with Koch's postulates
Define: pathogenic, "magic bullet", normal flora, normal microbiota, genus, species, prokaryote,
eukaryote, pasteurization, immunity, antibiotic, fermentation, bioremediation, Bacillus thuringiensis. -
ANSW-Magic Bullet: kills the microbe, but doesn't harm the host
What important roll do microorganisms play in the process of sewage treatment? (p.789-793) - ANSW-
Indicator organisms are used to indicate the possible presence of pathogens in water
What is the plural form of the words bacillus, coccus and genus? - ANSW-Bacilli, Cocci, Genera
What is the singular form of the words bacteria and media? - ANSW-Bacterium, Medium
Pasteur, possibly more than any other of the early scientists, contributed much to the study of
microbiology. List and explain all of Pasteur's contributions. - ANSW--Microbes can be killed with heat
-Pasteurization (flash heating to eliminate)
-Industrial Microbiology (use of microbes to make things)
Identify the following branches of the science of microbiology: bacteriology, immunology, epidemiology,
parasitology, protozoology, virology, and mycology, and genetic engineering. - ANSW-Bacteriology: the
study of bacteria
Immunology: the study of the body's specific defenses against pathogens
Epidemiology: Study of the occurance, distribution, and spread of disease in humans
Parasitology: The study of parasites
Protozoology: the study of protozoa
Virology: the study of viruses
Mycology: the study of fungi
Genetic engineering: the manipulation of gees for practical applications
List and explain Koch's Postulates. What was the reason that Koch formulated the postulates? What
bacterium was he studying at the time? Why have Koch's Postulates been so important to medical
science? - ANSW-Koch studied anthrax
1. same microbe observed in call cases
2. microbe grown in pure culture (only 1 microbe)
3. healthy animal innoculated
