Trichinella spiralis has been examined by electron microscopy after fixation in situ in the intestine of mice. The worms lie within the cytoplasm of cells of the intestinal mucosa and may occupy both absorptive and goblet cells. They cause little damage to host cells. A few worms have been seen protruding from tissue by SEM techniques. These unusual observations suggest that the nematodes may be capable of exit and reentry into the epithelium.
旋毛虫在小鼠肠道内原位固定后，已通过电子显微镜进行了检查。这些蠕虫位于肠黏膜细胞的细胞质内，可占据吸收细胞和杯状细胞。它们对宿主细胞造成的损害很小。通过扫描电子显微镜技术观察到一些蠕虫从组织中伸出。这些不同寻常的观察结果表明，线虫可能能够进出上皮组织。
