An electron microscope study of infected human louse gut cells and feces was made to determine whether a valid correlation exists between the increased resistance of Rickettsia prowazeki (in the louse feces) to adverse environmental influences and changes in the organism which might be reflected in its ultrastructure. Upon fine structural examination of this intracellular parasite as it passed from the louse midgut cell to the feces, it was apparent that no such morphological changes had occurred.
对受感染的人体虱子肠道细胞和粪便进行了电子显微镜研究，以确定普氏立克次体（在虱子粪便中）对不利环境影响的抵抗力增强与该生物体可能反映在其超微结构中的变化之间是否存在有效关联。在对这种细胞内寄生虫从虱子中肠细胞到粪便的过程进行精细结构检查时，很明显没有发生这种形态变化。
