Inadequate oxygen in turn damages the alveoli, the sacs of cells that transfer oxygen into the bloodstream...

The warm, moist environment, and possibly the concentration of carbon dioxide in the lungs, stimulates the bacterium to emerge from its protective spore. As each bacterium reproduces, it releases toxins, which eventually spread throughout the body and destroy tissue and organs...
