Abstract

Electron microscope observations on Thelohania sp. in the shrimp Pandalus jordani support the view that the Golgi complex in Microsporida is a "classical" one, composed of vesicular, vacuolar, and cisternal components. During development of the sporoblast, a portion of the Golgi complex is seen as an electron-dense reticulum enmeshing the core of the polar filament. Associated with the reticulum are electron-dense bodies. The reticulum and "dense bodies," reported in several previous publications, have not been well understood and have been given a variety of names. The evidence favors the view that these structures have secretory activity in which the reticulum concentrates or synthesized material, some of which takes the form of membrane-bounded granules. It is suggested that the most appropriate name for the reticulum is "reticulum golgien," and the the correct name for the "dense bodies" is the standard cytologic term, "secretion granules." The secretion granules apparently remain in the posterior part of the spore, and may be stored there for some as yet undetermined use.

摘要

对乔氏拟庸鲽虾体内的泰洛哈尼亚菌(Thelohania sp.)进行的电子显微镜观察结果支持以下观点:微孢子虫中的高尔基体是一种“典型的”高尔基体,由囊泡、液泡和扁平囊成分组成。在孢子母细胞发育过程中,一部分高尔基体表现为围绕极丝核心的电子致密网状结构。与该网状结构相关联的是电子致密小体。先前的几篇出版物中报道的这种网状结构和“致密小体”尚未得到充分理解,并且有各种不同的名称。现有证据支持以下观点:这些结构具有分泌活性,其中网状结构浓缩或合成物质,其中一些物质以膜结合颗粒的形式存在。有人建议,这种网状结构最合适的名称是“高尔基体网状结构”,而“致密小体”的正确名称是标准细胞学术语“分泌颗粒”。分泌颗粒显然留在孢子的后部,可能会在那里储存起来以供某种尚未确定的用途。
