title: [Electron microscopic study of several features of spore formation in type B Clostridium perfringens].
abstract: The authors carried out electron microscopy of the thin sections of Cl. perfringens, type B (strain No. 89). Material of middle electron density was revealed on the cell wall surface from the first hours of the culture growing; the cytoplasm displayed both rod-like incorporations with transverse striations, and phage particles. Different spore formation disturbances were revealed in the strain under study. In the majority of cells spore formation was blocked at the III--V stage. Besides, there were pseudospores, whereas mature spores were rarely encountered, and even those which did occur, were at the stage of growing.
