Immunological and physicochemical characterization of heat-labile enterotoxins isolated from two strains of Escherichia coli.
Heat-labile enterotoxins from Escherichia coli strains of human and porcine origins had identical subunit composition, arrangement, and size in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Immunological differences recently described by others were shown to reside exclusively in the B subunits.
