Effect of Escherichia coli on Fluid Transport across Canine Small Bowel MECHANISM AND TIME-COURSE WITH ENTEROTOXIN AND WHOLE BACTERIAL CELLS

Abstract

An Escherichia coli strain isolated from a patient with severe cholera-like diarrhea elaborates a partly heat-labile enterotoxin shown to cause prompt adenyl cyclase stimulation and isotonic fluid secretion by canine jejunum. Both responses disappear upon removal of the enterotoxin. The duration of action of a submaximal dose of this E. coli enterotoxin was brief, despite sustained exposure to the jejunum, suggesting inactivation of the enterotoxin by its interaction with the mucosa.
