Abstract

Virulent and avirulent gonococcal colonies were studied in the scanning electron microscope. Cells in virulent, in contrast to avirulent, colonies were found to be connected by numerous strands. After longer incubation periods, type 2 colonies segregated out regions of cells virtually lacking these strands. Cells within these areas probably represent avirulent segregants. The microstructure of individual colonies revealed no topographical differences. In certain colonies large smooth spherical cells were seen, probably representing wall-deficient gonococcal variants.

摘要

在扫描电子显微镜下研究了有毒力和无毒力的淋球菌菌落。与无毒力菌落相比，有毒力菌落中的细胞被发现通过大量细丝相连。培养较长时间后，2型菌落分离出几乎没有这些细丝的细胞区域。这些区域内的细胞可能代表无毒力的分离菌。单个菌落的微观结构没有显示出地形差异。在某些菌落中可见大的光滑球形细胞，可能代表细胞壁缺陷型淋球菌变体。
