Summary

Rat peritoneal neutrophils adhere to schistosomula of Schistosoma mansoni in vitro in the presence of antibody, complement, or both. Ultrastructural studies have demonstrated that cell adherence is not intimate, and that electron-dense secretions are not liberated onto the parasite surface in the manner described for eosinophils. Cytochemical techniques confirm that peroxidase is confined within intracellularly located neutrophil secretion granules. The metabolic burst is shown to operate during Fc-mediated interactions, but since morphological damage depends upon the presence of complement in the system, toxic oxygen products would seem not to be involved in the initiation of surface perturbation. Complement-dependent, neutrophil-mediated schistosomular damage is characterized by vesiculation of the tegumental outer membrane, an increase in density of the tegumental cytoplasm and the eventual development of focal lesions. The cells migrate laterally to push aside damaged surface tissues and then adhere intimately to the exposed musculature. Damage appears earlier when both antibody and complement are present in the system, and this correlates with higher killing efficiency. The frequently observed association of contaminant eosinophils with areas of parasite damage indicates that eosinophils and neutrophils may cooperate to effect schistosomular killing. In the presence of antibody alone, attached neutrophils exhibit intense phagocytic activity towards the antigen-antibody complex formed at the parasite surface. This phenomenon may account for the eventual detachment of cells and lack of significant parasite damage recorded in this system
