Abstract

This study aims to describe the ultrastructure of coiled musculature fibers component of and its role in this parasite transmission. The present work employs transmission electron microscopy to analyze musculature, revealing the presence of myosin and actin bands in the underlying epithelium, typical arrangement of the skeletal muscle. This study unravels for the first time the existence of a coil muscle component in which it seems to be responsible for the remarkable flexibility of the musculature of and the efficiency of its transmission method to reach a nearby fish host. The elasticity of the musculature described in this study may be comparable with the other specialized elastic musculature within the animal kingdom (i.e., lizards tongue). The clarification of the basic biology of these monogenean parasites and its musculature biochemical systems hold the promise of possible novel muscle targets for a new generation of antiparasitic drugs.

摘要

本研究旨在描述[寄生虫名称]卷曲肌肉组织纤维成分的超微结构及其在该寄生虫传播中的作用。目前的工作采用透射电子显微镜分析[寄生虫名称]的肌肉组织，揭示了其上皮组织中存在肌球蛋白和肌动蛋白带，这是骨骼肌的典型排列。本研究首次揭示了一种卷曲肌肉成分的存在，它似乎是[寄生虫名称]肌肉组织具有显著柔韧性及其传播方法能够有效到达附近鱼类宿主的原因。本研究中描述的肌肉组织弹性可能与动物界其他特殊的弹性肌肉组织（如蜥蜴舌头）相当。阐明这些单殖吸虫寄生虫的基础生物学及其肌肉组织生化系统有望为新一代抗寄生虫药物提供可能的新型肌肉靶点。
