Bacteria can evolve rapidly because they reproduce at a fast rate. |
|
Why can bacteria evolve rapidly? |
|
|
|
Stages of antibacterial resistance include: 1. Mutations of bacterial pathogens produce new strains. 2. Some strains might be resistant to antibiotics, and so are not killed. 3. They survive and reproduce, so the population of the resistant strain rises. 4. The resistant strain will then spread because people are not immune to it and there is no effective treatment. |
|
What are the stages of antibacterial resistance? Explain how bacteria can become resistant to antibiotics. |
|

|
MRSA is resistant to antibiotics. There are links with this content to
Antibiotics and painkillers. |
|
What is the bacteria MRSA resistant to? Discuss how the rate of development of resistant bacteria could be slowed down.
Discuss why there are few new antibiotics being developed, and suggest how drug companies might be encouraged to develop some. |

|
|
To reduce the rate of development of antibiotic resistant strains:
? doctors should not prescribe antibiotics inappropriately, such as treating non-serious or viral infections
? patients should complete their course of antibiotics so all bacteria are killed and none survive to mutate and form resistant strains
? the agricultural use of antibiotics should be restricted.

What should be done to reduce the rate of development of antibiotc resistant bacteria? Explain how antibiotic resistance has impacted on cleaning practices in Britain’s hospitals. |
|
|
|
The development of new antibiotics is costly and slow. It is unlikely to keep up with the emergence of new resistant strains |
|
Why can't medical professionals just produce new antibiotics to fight resistant bacteria? Role play: life without antibiotics. |
