Finally, you use a diagram to illustrate to Jay how some pathogens avoid phagocytosis, which is part of the innate immune defense. You tell him that Salmonella is able to avoid phagocytosis by preventing formation of the phagolyososome. Which of the following is NOT a way for a pathogen to avoid phagocytosis?
A) Some pathogens escape from the phagosome before it fuses with lysosomes.
B) Some pathogens survive the destructive environment within the phagolysosome.
C) Some pathogens avoid being recognized by phagocytes and thus avoid being engulfed by the cell.
D) Some pathogens kill phagocytes, often by using toxins to form pores in their membranes.
E) Some pathogens are serum-resistant, avoiding the killing effects of phagocyte complement proteins.

E) Some pathogens are serum-resistant, avoiding the killing effects of phagocyte complement proteins. This choice does not describe a mechanism for avoiding phagocytosis itself but rather a mechanism for resisting the effects of complement proteins in serum, which is related to but distinct from the process of phagocytosis.
