- Tuberculosis
- Causes
- Pathogens Mycobacterium tuberculosis & Mycobacterium bovis.
- Usually affects lungs-can attack any organ.
- Enters body by droplet infection.
- Transmitted to humans by infected milk (mycobacterium bovis)
- Pathogens Mycobacterium tuberculosis & Mycobacterium bovis.
- Means of Transmission
- Poor immune system. e.g. if you already have HIV
- Airbourne disease-tiny microscopic droplets. Via coughing, sneezing, ect.
- Only th active disease is contagious.
- Through close contact over a long period of time.
- Airbourne disease-tiny microscopic droplets. Via coughing, sneezing, ect.
- Transmitted easier in war, when TB becomes resistent to drugs and increased movement of people.
- Prevention
- Early recognition, vaccination, ventilation, germicidal UV light.
- BCG vacinne in the UK. Beforehand, skin test (Heaf test) introduces tuberculin to system and inflammation will occur if you are already immune.
- Early recognition, vaccination, ventilation, germicidal UV light.
- Treatment
- Antibiotics-full course must be finished. 3 or 4 tyoes to begin with, narrowed down to 2 or more eventually with different types of action. If only one type was used bacteria could become resistant.
- Bacterium can become resistant-growing problem.

- Poor immune system. e.g. if you already have HIV
- Global Impact
- 20% of people with TB also have HIV. Increasing due to increased poverty/homelessness; failure of people to take antibiotics; and HIV and AIDS epidemics. Increasing new resistant strains. Transmitted in cows milk and meat-less of an issue in developed countries.
