Question

A person eats food prepared on a kitchen counter covered with living infectious bacteria. Which of the following best describes an example of how the bacteria might resist the person's nonspecific immune defenses?

Answer 1

Phagocytes that try to engulf the bacteria are soon destroyed by enzymes produced by the bacteria.
B cells are blocked from binding to the bacteria antigens because of enzymes secreted by the bacteria.
Infection would not be able to destroy the bacteria.
Plasma cells that would normally mark the bacteria for destruction are avoided by the bacteria.
