Question 1
pts
True or False: Differential media is best suited for distinguishing between two
similar species of bacteria.
Correct!
True
Growth media does not contain restrictive factors, while selective media is best
used to encourage the growth of one microbe while simultaneously discouraging the
growth of the other. Since two similar species of microbes are being studied they
must be differentiated under similar but just slightly different conditions (differential
media).
False
Question 2
pts
A researcher is asked to determine if a sample contains Neisseria
meningitides. Knowing Neisseria meningitides is slow growing and other
foreign microbes may also be present in the culture, which type of media
would be best suited?

Growth media
Differential media
Correct!
Selective media
Selective media. If additional foreign microbes may be present in your sample and
you know Neisseria meningitides is slow growing, you must restrict the unwanted
microbes while supporting the growth of Neisseria meningitides. Thus, you are
selectively encouraging one microbes growth, while selectively restricting others.
Question 3
pts
What are the requirements of a fastidious microbe?
Your Answer:
The requirements of a fastidious microbe are essential nutrients to grow due
to the organism having complex growth requirments. Enriched media
contain the requirments needed to grow.
A fastidious microbe is an organism with complex growth
requirements such that if absent it will not grow. Enriched
medias thus contain these specific and essential nutrients
