Abstract
Opsonization with normal human serum, purified immunoglobulin G, or immunoglobulin G-deficient serum promoted phagocytosis of Listeria monocytogenes by human peritoneal macrophages. However, normal human serum was the most effective opsonin in elicting killing and chemiluminescent responses. Macrophages phagocytized and killed almost as much as polymorphonuclear leukocytes but produced considerably less chemiluminescence.
