What steps can be taken to prevent or slow down the evolution of antibiotic or pesticide resistance. SCIE206-1101A-20 Biology Assignment Name: Unit 4 Discussion
Board Deliverable Length: 3-4 paragraphs Details:
For many years, antibiotics have been effectively used to treat
bacterial disease; and pesticides have been used to protect our
agricultural crops from many kinds of pests, including insects,
worms (nematodes), fungi, or agricultural weeds, for example. A
growing concern for treating bacterial diseases or pest outbreaks
is the evolution of antibiotic or pesticide resistance by bacterial
or pest populations. Resistance means that a particular antibiotic
is no longer effective in treating a disease, or that a particular
pesticide will no longer prevent crop damage. This resistance can
be viewed as evolution of a new trait at the population level,
which is resistance to an antibiotic or to a pesticide. In this
assignment, you will explore specific examples of antibiotic or
pesticide resistance.
Assignment details: After reading materials about evolution and
about antibiotic and pesticide resistance in the text, the Course
Materials, the AIU Online Library and / or the Internet, answer the
following.
1.Select and describe one example of antibiotic resistance or
pesticide resistance. Be specific in your choice. ◦Describe the
background for your choice of resistance. Include details about the
disease or pest and the established control strategies. How have we
used antibiotics (to treat a particular disease), or pesticides (to
protect from a pest); and how has this changed?
2.Explain how the resistant trait evolved based on principles of
natural selection and evolution of a trait at the population
level.
3.For your specific example, what are the consequences of
resistance in terms of human health or crop loss / damage?
4.What steps can be taken to prevent or slow down the evolution
of antibiotic or pesticide resistance? Do you think we will succeed
in doing so? Why or why not?
Provide references in APA format. This includes a reference list
and in-text citations for references used throughout the
assignment. In your own words, please post a response to the
Discussion Board and comment on two other postings. You will be
graded on the quality of your postings. For assistance with your
assignment, please use your text, Web resources, and all course
materials.
