The morphology of the mucosal surface of samples from the small intestine of young protein-deficient pigs was examined by scanning electron microscopy. Three pigs had been infected with Ascaris suum for at least 58 days while 1 had remained uninfected; all pigs were housed and maintained under the same conditions, at the same time. The tissue samples collected at post mortem examination from pigs which contained A. suum showed varying degrees of villous atrophy and fusion. In addition, unusual small craters and as yet unidentified objects were observed at the surfaces of the enterocytes of Ascaris-infected pigs. These changes in mucosal morphology were not seen in the tissue taken from the uninfected pig. The possible association between the mucosal lesions and lactose maldigestion in young, protein-deficient pigs infected with A. suum is discussed.
通过扫描电子显微镜检查了幼年蛋白质缺乏猪小肠样本的黏膜表面形态。三头猪感染猪蛔虫至少58天，而一头猪未感染；所有猪在同一时间、相同条件下饲养和维持。在尸检时从含有猪蛔虫的猪身上采集的组织样本显示出不同程度的绒毛萎缩和融合。此外，在感染猪蛔虫的猪的肠细胞表面观察到异常的小坑和尚未识别的物体。未感染猪的组织中未发现这些黏膜形态变化。本文讨论了感染猪蛔虫的幼年蛋白质缺乏猪的黏膜病变与乳糖消化不良之间可能存在的关联。
