Abstract

SUMMARY: Scanning electron microscopy of intact fixed trophozoites of showed typical crescent-shaped organisms with clear polar structures. Examination of living organisms exposed to mouse peritoneal macrophages and L-cells and then fixed suggested that phagocytosis is one method of entry of the parasite into both phagocytic cells and those usually considered non-phagocytic. Antibody and accessory factor collapsed the organisms; irregular vacuoles appeared on their surfaces and cytoplasmic contents were extruded.
