Isolation of special antibodies which react only with homologous enterotoxins from Vibrio cholerae and Enterotoxigenic Escherichia coli.
Cholera enterotoxin (CT) and heat-labile enterotoxin (LT) produced by enterotoxigenic Escherichia coli share a common antigenic determinant. In addition, CT and LT each have a unique antigenic determinant. Antisera were prepared by immunoaffinity chromatography against these unique antigenic determinants, that is, antiserum that reacted with CT but not with LT and antiserum that reacted with LT but not with CT. Antiserum against the common antigenic determinant to CT and LT was also prepared by immunoaffinity chromatography. The specificities of these antisera were demonstrated by Ouchterlony double-gel diffusion tests and by neutralization of the activities of CT and LT to cause morphological changes in Chinese hamster ovary cells.
