. A 5-year-old boy is evaluated because of recurrent bacterial infections predominantly of the respiratory tract, soft tissue, and lymph nodes. Affected sites show microabscesses and granuloma formation. Staphylococcus aureus is frequently cultured from these lesions. A maternal uncle died with similar findings at 4 years of age. Laboratory studies show a deficient oxidative burst following appropriate stimulation. The most likely cause of the recurrent infections is a defect in which of the following enzymes? A) Adenine deaminase B) Catalase CMyeloperoxidase NADPH oxidase E) Superoxide dismutase
