Attachment of Neisseria gonorrhoeae to amnion cells in tissue culture is facilitated if the gonococci bear pili. This has been determined by studying the number of pilated, colony type 2 gonococci associated with amnion cells after incubation in vitro as compared with the number of nonpilated, colony type 4 gonococci present with amnion cells under the same conditions. These data are supported by light microscope findings. Electron microscope studies provide visualization of fine structure of gonococcal attachment. Gonococci are also found within amnion cells in this in vitro system.
如果淋病奈瑟菌带有菌毛,那么它在组织培养中与羊膜细胞的黏附会更容易。这是通过研究体外培养后与羊膜细胞相关的2型菌毛菌落淋病奈瑟菌数量,并与相同条件下与羊膜细胞共存的4型无菌毛菌落淋病奈瑟菌数量进行比较而确定的。这些数据得到了光学显微镜观察结果的支持。电子显微镜研究能够观察到淋病奈瑟菌黏附的精细结构。在这个体外系统中,还发现淋病奈瑟菌存在于羊膜细胞内。
