The Effect Of Cell-Free Fluids Prepared From Cultures Of Human And Animal Enteropathogenic Strains Of Escherichia Coli On Ligated Intestinal Segments Of Rabbits And Pigs

Abstract

The relatively labile (LT) form of the enterotoxin produced by pig-entero-pathogenic strains of Escherichia coli strongly dilated ligated segments of rabbit intestine; the more stable (ST) form had a weaker effect. Dilatation was also produced by LT-type preparations of some non-enteropathogenic pig strains.
