目的 观察宫川棘口吸虫虫卵、尾蚴及成虫的体被超微结构 ,为其分类及其生物学特性的进一步认识提供资料。 方法 通过实验感染的方式维持生活史循环 ,主要采用扫描电子显微镜观察虫体形态 ,光学显微镜观察发育过程。 结果 虫卵前端有卵盖、末端有皱褶增厚部分 ;尾蚴的口吸盘周围对称分布着有纤毛的乳突 ,有或无纤毛的凹陷及小孔 ;具纤毛的乳突在虫体的其余部分也有发现 ,可能起感觉器的作用。 结论 尾蚴的体被具有分泌、排泄功能 ;尾蚴尾部有鳍 ,有助于尾蚴在水中活动。
Objective To observe the ultrastructure of the eggs, cercariae and adults of Miyagi and Miyagi, providing information for the classification and further understanding of their biological characteristics. Methods The cycle of life history was maintained by means of experimental infection. Morphology of the parasites was observed by scanning electron microscopy and the developmental process was observed by light microscopy. As a result, there were oval capsum at the anterior end of the egg and thickening of the folds at the end. The ciliated masticulous ciliated mastoid was distributed around the mouth sucker of the cercariae, with or without ciliated pits and small holes; Some also found that may play a role in the sensor. Conclusion The body of cercariae is secreted and excreted. Fin tail of cercariae is helpful for cercariae to move in water.
