Antibiotic resistance
Biology · Secondary 3 · Medium · Antibiotic resistance
A patient has a bacterial ear infection. The doctor prescribes a 7-day course of antibiotics, but the patient stops taking them after 3 days when he feels better. How can this behaviour contribute to antibiotic resistance?
- It allows resistant bacteria to survive and reproduce after the sensitive ones are killed.
- It makes the patient’s immune system weaker so bacteria mutate faster.
- It causes the antibiotic to become more concentrated in the blood.
- It turns the bacteria into viruses that cannot be killed by drugs.
