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.
Methicillin resistant Staphylococcus aureus (MRSA) has become a big concern in hospitals throughout the country and the world, as have other antibiotic resistant bacterial strains.
The use, overuse, and abuse of antibiotics is accredited with creating these antibiotic resistant strains. Explain how this relates to natural selection.
Describe 12 of the things that people do (you can include individuals, doctors, health care professionals, hospitals, farmers, etc.) that contribute to this problem? Why?
How can you prevent or slow down the spread and further the selection of new antibiotic resistant strains of bacteria?
Are there things that you can personally do to reduce your risk or even to reduce the spread of these dangerous microbes?
What is your reaction to the following sign that is commonly found in restrooms? Is it significant to the discussion of antibiotic resistance?
