将沙门氏菌3、JO：R菌种导入鸡回肠。在感染18小时后的回肠切片上，用电子显微镜观察这些微生物与IleA！上皮细胞微绒毛的相互作用。位于微绒毛附近的微生物具有大的袋状mcmprane结合突起。在这些结构外可以看到一些电子密度较低的物质的条纹，这表明物质在沙门氏菌有机体和上皮细胞微绒毛之间移动。远离Ilea I微绒毛的生物没有发现这种袋状膜结合结构的存在。这些结构被认为含有沙门氏菌毒素。这些关于沙门氏菌3，LO：R生物的观察结果是新的，到目前为止还没有报道。
Salmonella 3,JO:r organisms were introduced into thchicken ileum. Ileal sections were examined 18 hr post-infection employing electron microscopy to study su�"race interaction of these organisms with the ilea! epithelial cell microvilli. The organisms located in the".close vicinity of microvilli have large bag-like mcmprane-bound protrusions. Streaks of some lightly electron-dense material were seen outside these struc tures suggestive of movement of materials between the Salmonella organisms and the epithelial cell microvilli. Organisms located away from the ilea I microvilli did not reveal the presence of such bag-like mem brane-bound structures. These structures are presumed to contain Salmonella toxin. These observations on Salmonella 3,lO:r organisms are new and have not been previously reported as far as known.
