对七只感染毛圆线虫的兔子和一只未感染的对照兔子的胃和小肠进行组织学切片观察。感染后12小时，在小肠中发现幼虫。起初，仅观察到少数幼虫通过绒毛间质毛细血管进入粘膜；大多数幼虫留在肠腔内的隐窝粘液内。我们认为基质中蠕虫的存在是幼虫迁移的结果。从系统学的角度来看，这种迁移被解释为原始圆线虫中肺迁移的祖先记忆。 (C) 2002 Elsevier Science B.V. 保留所有权利。
Observations were made on histological sections of the stomach and small intestine of seven rabbits infected with Trichostrongylus retortaeformis and from one uninfected control rabbit. At 12 h post-infection, larvae were found in the small intestine. At first, only a few larvae were observed entering the mucosa through capillaries of the stroma of villi; the majority of larvae remained in the intestinal lumen, within mucus of the crypts. We consider that the presence of the worms in the stroma is the result of a larval migration. From a phyletic point of view, this migration is interpreted as an ancestral memory of the pulmonary migration seen in the primitive Strongylida. (C) 2002 Elsevier Science B.V. All rights reserved.
