Microbiology Exams 1-7 from Rio Salado
College with accurate questions and
verified answers
Define bacteriology, mycology, parasitology, immunology, and virology.
......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
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.
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
, 4|Page
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
Describe emerging infectious diseases. ......answer.....HIV, AIDS, Ebola,
West Nile
How did the theory of biogenesis lead the way for the germ theory of
disease? ......answer.....The theory gave light to a whole new world of
studies. Without biogensis we wouldnt have discovered vaccines, or this
different diseases we know about now and how to treat them.
In 1864, Lister observed that patients recovered completely from simple
fractures, but compound fractures had "disastrous consequences." He
