Question 2

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?
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.

What are the requirements of a fastidious microbe?
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 required for the growth of a particular
subset of microorganisms.
