Biological Resistance:

More than 70 years ago, Alexander Fleming discovered penicillin and set in motion a medical revolution. In 1943,
penicillin was mass-produced and saved many wounded soldiers from death by bacterial infection. Yet even as we
enjoy the benefits of antibiotics, their use promotes antibiotic resistance in bacteria. By confronting bacteria with
antibiotics, we select for those that are resistant and change the course of their evolution. In fact, just three
years after the first mass-production of penicillin, resistant bacteria began to appear. View the animation to learn
more about the rise in antibiotic resistance.
1.
Can you use antibiotics for viruses?
2.
Does you body have any good bacteria? If so, give an example.
3.
What is one way an antibiotic can kill a bacteria?
4.
Why do some of the bacteria live when you take an antibiotic? What do they have?
5.
How do the bacteria reproduce?
6.
What happens to the proportion of resistance bacteria?
7.
How can a bacterium that is not resistant become resistant?
8.
Explain the role of evolution to biological resistance. ( hint: How do bacteria evolve resistance to chemicals?)
