A 36-year-old man is required to attend a
Pulmonary clinic as part of a contact investigation for a person who tested positive for tuberculosis. He works in a factory where he encounters a large number of
unvaccinated persons among whom the disease has begun to spread. Since the man
is properly vaccinated and his results are negative, this check is performed only a
once. Mycobacterium tuberculosis is a specific bacterium that is
able to survive after phagocytosis inside macrophages. Once it is engulfed by
macrophages, it starts to produce a protein called PtpA (protein tyrosine
phosphatase A). These molecules knock out two different mechanisms that the
macrophage needs to create the acidic environment necessary for bacteria to
break down. As a result, the tuberculosis bacteria hide inside the macrophages
and completely escape the attention of the immune system. When they multiply
sufficiently, they escape the cell and invade other parts of the body. What
should properly occur after phagocytosis and destruction of these bacteria
inside the macrophage?
