Sir Alexander Fleming
  • Discovered that certain fungi (penicillium) inhibited growth of staphlococcus bacteria
  • Used knowledge to formulate first antibiotic penicillin to be used medically
taking antibiotics
Taking Antibiotics
  • Persccriptions need to be followed exactly as directed from doctor
  • Biggest mistake = stopping antibiotics just because you feel better
  • ALWAYS finish perscription as directed
    • Can lead to antibiotic resistant infections
antibiotic resistance
Antibiotic Resistance
  • Antibiotics kill or stop the reproduction of pathogenic bacteria
  • In a colony some will be affected by drug, others will not
  • Immune system can target bacteria that is not affected and destroy pathogens
  • What happens if the immune system doesn’t get them all??
super bugs
Super bugs
  • Recently; antibiotic resistance has created a line of pathogens that are termed ‘Super Bugs’
  • They are resistant to antibiotics and are not easily defeated
  • Product of antibiotic resistance
development of super bugs
Development of Super Bugs
  • Colony of pathogens of resistant (green) and non-resistant types (red)
development of super bugs1
Development of Super Bugs
  • Antibiotics destroy non-resistant type
development of super bugs2
Development of Super Bugs
  • Resistant type given chance to re-colonize
  • New colony is 100% resistant
other ways super bugs arise
Other ways Super Bugs arise
  • If perscription is not completed, any remaining non-resistant cells can aquire resistance by mutation through exchange of DNA with resistant cells
