Week 4: Why are so many bacteria resistant to antibiotics?
Last week you learned that acquired resistance can result from mutation
Begin this week by watching the first 2.40 minutes of the following Ted Talks video which shows how bacteria can acquire and spread antibiotic resistance.
By the end of this week, you should be able to:
- explain how genetic mutations can give rise to antibiotic resistance that can be inherited
- describe the horizontal gene transfer mechanisms that allow antibiotic resistance to be transferred between bacteria
- discuss how evolution and natural selection maintain antibiotic resistance in bacteria.
