Antibiotic resistance
Biology · Secondary 4 · Medium · Antibiotic resistance
A patient is given antibiotics for a bacterial throat infection but stops taking them after two days when she feels better. How can this behaviour contribute to antibiotic resistance?
- Partially treated bacteria with resistant mutations survive and reproduce.
- Antibiotics permanently change the patient’s DNA to resist bacteria.
- The antibiotics kill only viruses, leaving all bacteria unchanged.
- Short courses of antibiotics become more concentrated in the blood.
