When used appropriately, antibiotic treatment can effectively reduce bacteria populations and help fight infections. However, antibiotic treatments can have unintended effects. What is one concern when using antibiotics?

#Unit 7. System Physiology – Animal
  1. Antibiotics also damage animal cells, so they can be more harmful than a bacterial infection.
  2. Antibiotics cause viruses to become more effective at infecting cells.
  3. Each antibiotic is only effective against one type of bacteria, so effects on infection are limited.
  4. Antibiotics may also kill the beneficial bacteria of the microbiome, thereby disrupting digestive health.
