Answer:

TB is caused by the bacterium M tuberculosis. The infection destroys patients' lung tissue, causing them to cough up the bacteria, which then spread through the air and can be inhaled by others. ... The new research shows that in patients with TB, there is an increase in levels of an enzyme called MMP-1 in their lungs.
