Antigenic similarity of heat-labile enterotoxins from diverse strains of Escherichia coli.


With use of the rabbit intestinal loop model, heat-labile enterotoxins from 21 Escherichia coli strains isolated from a wide spectrum of patients with diarrheal diseases were all neutralized to high titer by two antisera prepared against enterotoxins of either E. coli or Vibrio cholerae. These findings suggest marked immunological similarity among heat… (More)
