One of the important inherited defects in the second line of immune defense is a condition called chronic granulomatous disease. What is this disease, and how is it caused?
What will be an ideal response?
Chronic granulomatous disease is a type of primary immunodeficiency. It is an inherited condition seen in children who have recurrent infections, especially with bacteria. It is due to the inability of phagocytes to produce reactive forms of oxygen and therefore fail to kill ingested bacteria. A CBC would have normal levels of lymphocytes.
