Antibiotic Resistant Bacteria

• antibiotic resistance

  when bacteria used to kill a drug isn't affected by it anymore
• stages of antibiotic resitance

  • mutation in a bacterial pathogen produces a new strain
  • some strains might be resistant to antibiotic so are not killed
  • they survive and reproduce
  • the population of resistant strain rises
  • the resistant strain will spread as people are not immune and there is no effective treatment
• ways to reduce rate of development of strains

  • using antibiotic when necessary
  • completing course
  • good hygiene & sanitation
• new antibiotics are not being discovered due to high costs and limits ability to combat
