[Ultrastructural organization of Mycobacterium tuberculosis processed by cryogenic ultratomy].

The ultrastructural organization of M. tuberculosis has been studied by the method of cryo-ultratomy. The cell-wall structures and the connective formations localized in the cytoplasm between parallel intracellular membranes have been revealed. Ethylene glycol and polyvinyl alcohol have been shown to be the most suitable cryoprotecting agents.
