[Salmonella typhi L-transformation process in in vivo experiments using diffusion chambers]

The process of L-transformation of S. typhi was studied under conditions of diffusion chambers implanted into the abdominal cavity of rabbits with different immunological status. The process of L-transformation of S. typhi in vivo was induced by the action of humoral immunity factors. No unbalanced growth forms and L-forms of S. typhi were found to appear in the organism of nonimmune animals.
