Abstract
Summary
The metabolic activity of human polymorphonuclear neutrophils (PMN) was studied following the ingestion of polystyrene latex spheres (1.08 μ), heat-killed S. aureus (0.8 μ) or heat-killed Micrococcus sp. (1.2 μ). Phagocytsois of heat-killed bacteria resulted in a greater postphagocytic increase in oxygen consumption and hydrogen peroxide production than did phagocytosis of latex particles. These data suggest that the nature of the ingested particles has an influence on postphagocytic metabolic events.
