Causes of Tuberculosis
Pulmonary tuberculosis is usually caught from someone by coughing and sneezing tubercle bacilli. The TB germ has a thick capsule, and can survive dry and usually hostile conditions (although it is killed by UV light eg sunlight).
In countries where unpasterised milk is drunk TB may be transmitted in infected milk from cows with Bovine Tuberculosis.
