  • TUBERCULOSIS
    • CAUSES
      • Mycobacterium tuberculosis
      • Droplet infection
        • Overcrowding
        • Foreign travel, refugees and immigration
      • Increased susceptibility
        • Malnourishment
        • Other illness
        • Immune disorders
          • HIV/AIDS
        • Multidrug resistant strains
      • Mycobacterium bovis
        • Cattle
          • Infected milk
          • Close contact with cows
      • Drug use (needles)
    • SYMPOTOMS
      • Respiratory system
        • Damage or destruction of lung tissue
        • Final symptoms
          • Coughing up blood
          • Weakness
          • Death
        • cough
      • Immune system
        • Waxy layer protects from macrophages in primary
        • Target T cells
        • Reduce antibody production
        • Opportunistic infections
      • Fever
      • Night sweats
      • Appetite and weight loss
      • Tired and listless
    • TREATMENT
      • Long course of antibiotics
        • Many different types at first
        • Then 4-7 months of 2 types
    • CONTROL
      • Improve living standards
      • Pasteurising milk
      • Immunisation
    • PRIMARY INFECTION
      • Caught by 30% of those exposed
      • Slow multiplication in lungs
      • No obvious symptoms
      • Tubercule
        • Macrophages
        • Dead bacteria
      • Some bacteria may survive!
        • Wait until weakened
    • ACTIVE TUBERCULOSIS
      • Wait until weakened
      • 80% are a reactivation of primary infection
    • DIAGNOSIS
      • Chest x-ray
      • Bacterial DNA?
