The results of the detection of Shiga toxin antigen in culture filtrates of 73 enterobacterial strains by the methods of countercurrent electrophoresis and coagglutination, as well as their correlation with the presence of other factors of virulence, O- and K-antigens, have been analyzed. Sharply pronounced inverse correlation between the capacity of enterobacteria to synthesize Shiga (Shiga-like) toxins and their capacity to synthesize acidic polysaccharide surface-specific K- (Vi-) antigens has been established.
