Question

Quizplus · Accepted Answer

The chemicals in the cell wall of Mycobacterium tuberculosis prevent the fusion of phagocytic vacuoles with lysosomes, which normally would lead to the destruction of the bacteria. As a result, the bacterium can survive and replicate inside of the phagocytic cell, leading to the development of tuberculosis. Complement proteins and antibodies may play a role in fighting the infection, but they are not the primary means of defense against Mycobacterium tuberculosis. The bacterium does not produce chemicals that destroy the macrophage housing the bacterium.
