IPAC Final Exam - Questions With Appropriate
Solutions
Microorganism Correct Answer - often are unicellular, and
cannot be seen without a microscope
What are the groups of microorganisms? Correct Answer - 1.
protozoa
2. fungi
3. bacteria
4. viruses
Protozoa Correct Answer - Unicellular creatures that are able
to move either by flagella or amoeboid motion. Some protozoa live
in our bodies without causing harm but a few are responsible for
disease.
Fungi Correct Answer - A very diverse group of
microorganisms that can be divided into yeasts and molds. Yeast is
unicellular and mold is commonly multicellular.
Bacteria Correct Answer - Tiny unicellular organisms, do not
have an organized nucleus. They are found everywhere there is
moisture and nutrients.
Viruses Correct Answer - Smaller than bacteria and have a
simple structure. Viruses rely on a host to reproduce and replicate.
Shapes of bacteria Correct Answer - 1. Cocci: spherical or
round
2. Rods or bacilli: rectangular shaped boxes
3. Spirilla: curved or spiral shaped rods
, Importance of gram reaction Correct Answer - Looking at the
Gram reaction and shape of bacteria is often the first step in
identifying them in the laboratory. The gram reaction determines
the effectiveness of certain antibiotics and disinfectants.
6 groups of gram reactions Correct Answer - Gram positive
cocci
Gram negative cocci
Gram positive rods
Gram negative rods
Gram positive spirilla
Gram negative spirilla
Endospores Correct Answer - A small number of bacteria are
able to produce a special type of spore within the bacterial cell.
Vegetative cells Correct Answer - bacterial cells that do not
contain endospores.
Colony Correct Answer - A visible mass of bacteria that
develops on the surface of a solid culture medium after a period of
time.
Host Correct Answer - organism that is the target of an agent
Virulence Correct Answer - ability of a pathogen to cause
disease to a host
Reservoirs of infectious microorganisms Correct Answer - 1.
humans
2. animals
3. non-living
