1. Which of the following would be most valuable to confirm the
identification of microorganisms isolated during a food poisoning
outbreak? identification of microorganisms using microscopic,
cultural, and physiological characteristics
2. what three main approaches can be used by microbiologists to
identify microorganisms? genetic - bacteria can be identified by
their DNA sequence, immunologic = bacteria can be identified by
antibody binding assay, and phenotypic - phenotypic identification
includes observing bacterial morphology and staining properties as
well as biochemical testing
3. which method used in bacterial identification usually require
culturing of the unknown bacteria? phenotypic
4. which of the following is an example of a morphological
characteristic that could be used in the bacterial identification
process? Cell shape-is a key morphological property that can
readily be determined by observation of a stained smear
5. which of the following is an example of a culturing requirement
that could be used in the bacterial identification process oxygen
preferences
6. which of the following are examples of physiological
(biochemical) characteristics that could be used in the bacterial
identification process presence of specific enzyme; ability to break
down lipids.; ability to ferment glucose.
, 7. Bergey's Manual is an excellent resource for the identification of
fungi and viruses as well as bacteria false
8. the 9th edition of Bergey's Manual of determinative bacteriology
was designed solely for ____. identifying bacteria that already
have been cultured and phynotypically examined
9. which of the following types of media might be particularly helpful
in the isolation of a single bacterial species from mixed bacterial
culture differential; selective.
10. which of the following methods could be used to isolate
bacteria from a mixture serial dilution followed by spread plating;
loop dilution pouring plating; streak plating.
11. Which of the following would be starting point for
identifying an unknown bacterium? Gram staining
12. Multiple bacterial species can have similar staining reactions
and microscopic morphology True
13. the name of the reference book that provides information
about the staining properties, morphology, and biochemical
reactions of all known bacterial species is ___ manual bergey's
14. a standard set of biochemical tests is used to identify all types
of bacteria, regardless of morphological and cultural characteristics
false
