title: [Ultrastructure of Clostridium tetani. I. Structural features of the surface structures of vegetative cells].
abstract: Crest-like structures formed by internal layer of cell wall and cytoplasmic membrane were revealed in G1.tetani 471 by electron microscopy with the use of negative contrasting, ultrathin sections and freezing-etching. The transverse section of these crest-like structures was 56.3 nm and they were localized 4 to 6 in one row girdling the protoplast in different directions. Ring-like subunits located in rows with the periodicity of 5.9 nm, perpendicularly to the long axis of the cell, were revealed on the surface of the cell wall.
