Resistant Antibiotics Bacteria Problem Mutate Mutations Inidividual Survive

Antibiotic resistance arises from bacterial mutations; resistant bacteria survive and reproduce, leading to strains that cause untreatable infections.

Antibiotic resistance can develop through bacterial mutation, where resistant strains survive, reproduce, and increase in number, potentially causing untreatable infections.

Front What is a problem that antibiotics might have?
Back
  • Bacteria can mutate - sometimes mutations cause them to be resistant to an antibiotic
  • Inidividual resistant bacteria will survive and reproduce, and the population of resistant stain will increase
  • This is an example of natural selection
  • This resistant strain could cause a serious infection that can't be treated by antibiotics
