title: [Yersinia L-transformation in experimental pseudotuberculosis].
abstract: An experiment on guinea pigs infected with virulent Y. pseudotuberculosis has revealed for the first time that in the host body Yersinia cells undergo ultrastructural changes, characteristic of L-transformation. These changes are manifested by damages in the cell wall and peptidoglycan layer of bacteria, dramatic expansion of the peri-plasmatic space, appearance of spheroplast bacterial cells. Myelin-like structures are formed around dead bacteria. These changes reveal one of the possible mechanisms which may render Yersinia harmless in convalescent patients, as well as contribute to the development of relapses of Y. pseudotuberculosis infection.
