An attempt is made in this paper to define more clearly the tegumental microstructure of the schistosome, Heterobilharzia americana. The adult parasites were examined with scanning electron microscopy at 75-10000 magnifications. The morphology of the oral and ventral suckers, the tegument, and the gynecophoral canal with the in copula female were closely scrutinized. The tegument of the female is simple and uniform in structure, an adaptation which may allow for a more efficient mode of penetration through the smaller mesenteric venules. The male tegument, however, is characterized by papilla-like elevations of irregular size, shape, and distribution. These papillae may represent different kinds of sensory endings.
本文旨在更清晰地界定美洲异毕吸虫的皮层微观结构。使用扫描电子显微镜在75至10000倍放大倍数下对成年寄生虫进行检查。仔细观察了口吸盘和腹吸盘、皮层以及含有交配雌虫的抱雌沟的形态。雌虫的皮层结构简单且均匀，这种适应性可能使其更有效地穿透较小的肠系膜小静脉。然而，雄虫的皮层特征是有大小、形状和分布不规则的乳头状隆起。这些乳头可能代表不同类型的感觉末梢。
