柞蚕微孢子虫在柞蚕体内增殖的组织病理学研究

Study of the Histopathology on Multiplication of the Nosema pernyi in Tassah Silkworm

本试验用偶氮红和苯胺兰对柞蚕微孢子病蚕组织切片进行复染后光镜观察；依常规方法制成柞蚕微孢子虫（ＮｏｓｅｍａｐｅｍｇｉＷｅｎｅｔＤｉｎｇ）和柞蚕微孢子虫病蚕组织的超薄切片和扫描电镜试材后进行电镜观察和拍照．结果表明：柞蚕的中肠、丝腺、脂肪体为易感组织，后期感染肌肉、马氏管、气管管壁细胞，最后真皮细胞亦被感染，同时也查明了上述组织细胞的病理变化。

The histological slides of tassahsilkwormwhich infeCtal by microsporidia (Nosema pernyi)were observed under the light microscope after restaining with the azofuchsine and aniline bloe.blue.infected thenes were also observed under scanning electronic microscopes (SEM) and transmission electronic microscopes (TEM). The results that the midgut,silkglands and fat body were infected at first,and the next infected organs were muscle, Malpinghian tubes and the tractal wall, the last infected organ was epidermis. The pathological procedureemployed by the pest in the they of tassah silkworm was disscused in this paper.
