Antibiotic resistance

Question 1

Why are resistant bacteria a challenge?

Answer 1

• reproduce rapidly
• mutations produce new strains(eg MRSA)
• resistant strains survived and reproduce
• resistant strains spread

Question 2

How to prevent resistance strains appearing

Answer 2

Doctors to stop prescribing antibiotics innapropiately
Patients completing the antiobiotic course
Agricultural use of antibiotics should be restricted

Question 3

What is MRSA?

Answer 3

MRSA is methicillin resistant staphylococcus aureus which is spread when doctors go from patient to patient and as of this it is spread

Question 5

Why can bacteria evolve rapidly?

Answer 5

They reproduce at a fast rate

Question 6

What do mutations of bacterial pathogens produce?

Answer 6

New strains

Question 7

How does the population of the resistant strain increase

Answer 7

Natural selection

Question 8

Is MRSA resistant to antibiotics?

Answer 8

Yes

Question 9

What is bad about the development of new antibiotics?

Answer 9

It is costly,slow and is unlikley to keep up with the emergence of new resistant strains
