摘要

采用改进的超薄切片技术研究了分枝噬菌体B-1在宿主细胞中的增殖过程。核装置的外观在整个潜伏期没有改变。感染后约30分钟,在靠近核器的密度较低的区域出现噬菌体状致密颗粒,偶尔在核器边缘出现。根据作者的解释,密度较低的区域可能与噬菌体增殖病灶相对应,但没有像在核装置中看到的那样充满细链原纤维阵列。在潜伏期结束时,与成熟噬菌体颗粒一起,在裂解的细胞内外经常可以看到空的噬菌体头。此外,在潜伏期细胞内可能存在空头膜

Light and electron microscope studies of mycobacterium--mycobacteriophage interactions. III. Further studies on the ultrathin sections.
The process of multiplication of mycobacteriophage B-1 in its host cell was studied by means of an improved technic of ultrathin sectioning. The appearance of the nuclear apparatus was not altered throughout the latent period. Phage-shaped dense particles appeared about 30 minutes after infection in less dense areas neighboring the nuclear apparatus and occasionally at the margin of the nuclear apparatus. The less dense areas, which may correspond to the phage multiplication foci according to the authors' interpretation, were not filled with such arrays of fine-stranded fibrils as are seen in the nuclear apparatus. Empty phage heads could frequently be seen within and outside the lysed cells, along with the mature phage particles, at the end of the latent period. Moreover, it was indicated that empty head membranes may possibly exist within the cells during the latent period
