Antibiotics
Biology · Secondary 3 · Hard · Antibiotics
Antibiotics such as erythromycin are often prescribed to treat bacterial infections like Campylobacteriosis. Why are these antibiotics not effective against viral infections such as influenza?
- Viruses reproduce too quickly for antibiotics to work.
- Viruses do not have the cell structures that antibiotics act on.
- Viruses are larger than bacteria so antibiotics cannot enter them.
- Viruses already contain natural antibiotics that cancel the drug’s effect.
