title: [Ultrastructure of the L forms of cholera and NAG vibrios].
abstract: Ultrastructure of L-forms of cholera and NAG-vibrios obtained under the effect of penicillin, tetracycline, in prolonged cultivations, and isolated from the external environment was studied. There proved to be no principal differences in their ultrastructural organization. Cells of sphero- and protoplastic type were distinguished in the colonies. The presence in the cell cytoplasm of mesosomes of the lamellar, vesicular type, myelin-like structures, multiple ring-like formations liberated into external environment, and freely lying membranes served as the peculiarity of the L-forms under study. Budding process as a result of which there formed elemental bodies was revealed.
