The fine structure of normal and antibody-coated Tritrichomonas foetus cells and their interaction with rat peritoneal neutrophils was studied. Peritoneal neutrophils were obtained by glycogen stimulation. The neutrophils readily associated with and killed the parasites, which were subsequently ingested. The process involved activation of the respiratory burst, as demonstrated by the use of cytochemical methods. Images were obtained indicating that binding of parasites to the neutrophil surface triggers an exocytic response with release of oxygen-derived products. Cytochemical localization of acid phosphatase and peroxidase activities showed that leukocyte granules fused with the parasite-containing phagocytic vacuoles. We also showed the cytochemical localization of alkaline phosphatase in the parasite-neutrophil interaction.
