title: [Effect of antibiotic action on the submicroscopic structure of Salmonella. The action of monomycin on S. typhi].
abstract: The effect of subinhibitory concentrations of monomycin on the submicroscopic structures of 2 strains of S. typhi, 5 and 799 was studied. It was shown that formation of filamentoue forms, separation of the cell wall, thinning out of the cytoplasm granular component, increasing of the size of the matter with low electron optic density of fine granular structure were common in the cell response of both strains. Formation of vacuoli containing the thinned out granular component, filterable elements and complex membrane structures followed by their liberation into the medium and formation of the forms devoid of the cell walls was a characteristic peculiar property of the cell response in strain 799. The cells of strain 5 were characterized by formation of large granular osmiefilic matters and their excretion from the cells.
