Natural Selection and Antibiotic-Resistant Bacteria

SCIENTIFIC CONCEPTS / PROCESSES

  • Creating models is one way to understand and communicate scientific information
  • Graphing data can reveal patterns that are not apparent from data tables.
  • Most infectious diseases are caused by microbes
  • The human body has natural defenses against infectious diseases
  • Antibiotics are effective against many bacterial infections, but not against viral infections
  • Antibiotics can be effective against bacterial infections only if the entire course is completed as directed

Why is it important to take an antibiotic as prescribed? Students model the effects of antibiotics on the population of disease-causing bacteria during an infection. During the simulation, some groups complete the full course of antibiotics, while others miss doses. They then graph populations of more-resistant and less-resistant bacteria. Students observe the selection of more-resistant bacteria that can take place if antibiotic treatment is intermittent or discontinued prematurely. Through this activity, students learn why its important to take the full course of antibiotics.
