[Immunoelectrophoretic analysis of the antigenic composition of Salmonella typhi in the process of L transformation and reversion].

In the study of the antigenic composition of S. typhi L-forms and their revertants were determined. The stable L-forms were characterized by profound disturbances in the synthesis of Vi- and H-antigens. After reversion to bacterial forms all the revertants under study showed the complete restoration of their bacterial antigenic structure.
