A child is hospitalized for a series of chronic bacterial infections and dies despite
heroic efforts. At autopsy, the physicians are startled to see that the child's white
blood cells are loaded with vacuoles containg intact bacteria. Which of the following
explanations could account for this finding? A defect in the
a. Golgi appartus prevented the cells from processing and excreting the bacteria.
b. lysosomes of the white blood cells prevented the cells from destroying engulfed
bacteria.
, c. surface receptors of the white blood cells permitted bacteria to enter the cells.
d. rough endoplasmic reticulum prevented the synthesis of the antobodies (defensive
proteins) that would have inactivataed the bacteria.
e. cell walls of the white blood cells permitted bacteria to enter the cells.
