Chemical and Physical Control of Microbes and Drugs
What are the methods of chemical control that we discussed?
Be able to identify
whether a given method is effective at killing all, most, or some microbes.
What is the difference between microbicidal and microbistasis? Provide
examples of each.
Identify the types of microbes that would fall in the categories of high, moderate,
and least resistant to antimicrobial agents.
What is the definition for microbial death? How is this different from how we
define death in larger, eukaryotic organisms, such as animals? Why is the
definition for microbes different than for humans?
What is the relationship between the number of viable microbial cells and time
after administration of an antimicrobial agent? Will it be the same for all agents?
How would the concentration of the antimicrobial agent affect this relationship?
Define antibiotic. Where in nature do we find these? How antibiotics different
