Development of Resistance to antimicrobial drugs:

What is the difference between a natural, semisynthetic, and synthetic antibiotic?
How was the first natural antibiotic discovered? (To answer this question, identify the
antibiotic, distinguish between the fungus and the antibiotic, explain where the antibiotic
came from, and explain how people knew the antibiotic had antibiotic properties.)
Give an example of a strain of bacteria (Genus and species) that is now resistant to
commonly used antibiotics (identify the specific antibiotic).
Describe the physiological mechanism used by individual bacteria to resist the antibiotic
listed in part “3” of this Thought Question. For example, the mechanism could be
modification of drug, modification of target, prevention of drug penetration, overproduction
of target, or target mimicry. (This means that you must choose a strain of bacteria that we
know the characteristic of the bacteria that allows the bacteria to be resistant.)
How do populations (or strains) of microbes evolve resistance to antimicrobials? (For this
question, explain how random mutations and the variation in susceptibility within a
population affect the development of resistant strains?
Why is antibiotic resistance a problem?
