Antibiotic resistance

Question 1

Example of an antibiotic

Answer 1

Penicillin

Question 2

How can bacteria evolve to become antibiotic-resistant

-b… can develop random m… in their D…
-this can lead to c… in the bacteria’s c… eg. being less a… by an …
-this can lead to …-resistant r… forming, as the g… for antibiotic r… becomes more c… in the p…

Answer 2

-bacteria can develop random mutations in their DNA
-this can lead to changes in the bacteria’s characteristics eg. being less affected by an antibiotic
-this can lead to antibiotic-resistant restraints forming, as the gene for antibiotic resistance becomes more common in the population

Question 3

What is an example of a “superbug” that is early hard to get rid of

Answer 3

MRSA

Question 4

Why is antibiotic resistance becoming worse

Answer 4

-the overuse and inappropriate use of antibiotics

Question 5

Ways to prevent antibiotic resistance

Answer 5

-take the full course of antibiotics so that all the bacteria is destroyed
-don’t overuse antibiotics
-developing new drugs

Question 6

How is antibiotic resistance a problem in farming

-a… are given to farm … to prevent them from becoming i…, and to make them grow f…
-this can lead to the d… of antibiotic resistant b… in the animals which can s… to the h…

Answer 6

-antibiotics are given to farm animals to prevent them from becoming ill, and to make them grow faster
-this can lead to the development of antibiotic resistant bacteria in the animals which can spread to the humans

Question 7

What is the issue surrounding developing new antibiotics for antibiotic resistant bacteria

Answer 7

-the rate of development is very slow, so we can’t keep up with the demand
-it is very expensive
