Colonial-morphological variants of Bacillus thuringiensis var. Galleriae were studied by electron microscopy. The S variant was found to be asporogenous, whereas the R variant produced mature spores. Morphological modifications in the cell were followed in the course of sporulation. Spores were shown to have thin filamentous and tubular protrusions which had not been so far described in crystalliferous bacteria. Preparations from colonies of the R variant contained peculiar structures which resembled phage tails. A possible function of these structures is discussed.
通过电子显微镜研究了苏云金芽孢杆菌蜡螟变种的菌落形态变异体。发现S变异体不产芽孢，而R变异体产生成熟芽孢。在芽孢形成过程中追踪细胞的形态变化。结果表明，芽孢具有细丝状和管状突起，这在产晶体细菌中尚未见报道。来自R变异体菌落的制剂含有类似噬菌体尾部的特殊结构。讨论了这些结构可能的功能。
