Restoration of the ability of hypogammaglobulinemic serum to support opsonophagocytosis and intracellular killing of Bacteroides fragilis and Bacteroides thetaiotaomicron by human polymorphonuclear leukocytes was achieved by supplementation with normal human immunoglobulin M, but not with normal human immunoglobulin G. Polymorphonuclear leukocyte bactericidal activity in the presence of immunoglobulin A-deficient human serum was equivalent to that observed in the presence of normal human serum.

Abstract The effects of bacterial neuraminidase on production of hydrogen peroxide (H2O2) and killing of Staphylococcus aureus by human polymorphonuclear leukocytes (PMN) were studied. The concentration of H2O2 was measured by the disappearance of scopoletin fluorescence in the presence of horseradish peroxidase. The results indicated that desialylation of human PMN inhibited the stimulation of H2O2 production during phagocytosis. It also markedly impaired the killing of S. aureus. Impaired killing of S. aureus by desialylated PMN was due to impaired intracellular killing rather than defective phagocytosis.

Tetrazolium Reduction

Normal human polymorphonuclear leukocytes (PMN) placed in anaerobic chambers reaching pO2's of less than 5 mm Hg fail to generate O2-, iodinate ingested particles, and stimulate glucose-1–14C oxidation through the hexose monophosphate shunt. The observation that anaerobic cells are incapable of generating O2- or reducing nitroblue tetrazolium (NBT) to formazan supports the idea that NBT reduction in phagocytizing PMN is due exclusively to oxygen-dependent O2- generating oxidase which is deficient in chronic granulomatous disease leukocytes, despite their hyperphagocytic capacity.
