Microbiology Exams 1-7 from Rio Salado
College with accurate and verified questions
covering microbial structure and function,
bacterial growth, genetics, immunology,
infectious diseases, and laboratory
techniques. AND WELL VERIFIED
ANSWERS
Identify the importance of Koch's postulates. .-ANSWER--Proved that
microorganisms caused disease
Explain how Pasteur's work influenced Lister and Koch.
,2|Page
.-ANSWER--Because he participated in the development of germ theory
(idea that microorganisms might cause disease)Coined the term vaccine and
that the protection from disease or recovery is called immunity, and
discovered that avirulent bacteria can be used to cure fowl cholera
Identify the importance of Jenner's work. .-ANSWER--He demonstrated that
inoculation with cowpox material provided humans with immunity from
small pox
Identify the contributions to microbiology made by Ehrlich and Fleming. .-
ANSWER--Ehrlich introduced an arsenic containing chemical called
salvarsan to tx syphilis
Flemming observed that mold (penicillium) inhibited the growth of a
bacterial culture.
Define bacteriology, mycology, parasitology, immunology, and virology.
,3|Page
.-ANSWER--Bacteriology: the study of bacteria
Mycology: the study of fungi
Parasitology: the study of parasitic protozoa and worms
Immunology: the study of immunity
Virology: study of viruses
Explain the importance of recombinant DNA technology.
.-ANSWER--bacteria can produce substances such as proteins, vaccines, and
enzymes
List at least four beneficial activities of microorganisms.
.-ANSWER--Microorganisms degrade dead plants and animals and recycle
chemical elements to be used by living plants and animals. Bacteria are used
to decompose organic matter in sewage, and bioremediation processes use
bacteria to clean up toxic wastes. Bacteria are being used to control insect

populations, and microbes are commonly used to make products such as
food and chemicals (called biotechnology).
List two examples of biotechnology that use genetic engineering and two
examples that do not. .-ANSWER--agriculture to protect plants from frost
and insects and to improve the shelf life of products
Define normal microbiota and resistance. .-ANSWER--This distinction is a
balance between the disease-producing properties of a species of a microbe,
and the host's resistance (the ability to ward off diseases). When resistance is
low in the host, an infectious disease may occur, one in which pathogens
invade a susceptible host.
Define and describe several infectious diseases. .-ANSWER--VRE, PNU,
MRSA, CDIFF
