Abstract

|
Ultrastructural changes of Entamoeba histolytica, a concomitant strain YS-9, which was . treated in the immune serum was examined. The amoebae in the serum became immobilized state from about 30 minutes of the treatment and recovered at about 60-90 minutes, In the cells of control group, helix structures were scattered throughout the cytoplasm. The particles comprising the helix structure averaged 20 nm in diameter. At the beginning stage´ of the immobilization, helical aggregates(chromatoid body) which associated with vacuoles appeared abundantly in the cytoplasm, but gradually tended to aggregate along peripheral region of the cell, specially in intactly immobilized state. Each parallel array of aggregates measured about 45 nm in width. When the cells became remobilize, pseudopodia appeared again, but helical aggregates disappeared and numerous helix structures were observed in the cell periphery.. Di4tribution of glycogen particles showed no change, and acid phosphatase activities were seen is both the ´immobilized and the control group. The reaction was markedly noticed in the vacuoles.
