Exam Tips: Antibiotics vs Other Treatments

Common Exam Mistakes to Avoid:

  • Don't say: "Antibiotics kill viruses" - they only work on bacteria
  • Don't confuse: Antibiotics with antiseptics or disinfectants
  • Don't forget: Fleming discovered penicillin, not all antibiotics
  • Remember: Resistance is due to natural selection, not bacteria "learning"

Key Comparisons:

Infection Type Treatment Examples Outcome
Bacterial Antibiotics Pneumonia, strep throat Can be cured
Viral Antivirals (limited), rest, symptom relief Cold, flu, COVID-19 Usually self-limiting
Fungal Antifungals Thrush, athlete's foot Can be treated

Quick Recall Flashcards

What are antibiotics and what do they target?
Antibiotics are chemicals that kill bacteria or stop them from growing. They target structures that bacteria have but human cells do not, such as cell walls. Examples: penicillin, amoxicillin, streptomycin.
Why do antibiotics NOT work against viruses?
Antibiotics target bacterial cell walls and bacterial processes. Viruses do not have cell walls and use the host cell's own machinery to reproduce. There is nothing for the antibiotic to target in a virus.
