Abstract
Summary: Intestinal permeability in dogs with small intestinal disease was measured by quantitation of 24-hour urinary excretion of 51Cr-labeled EDTA following intragastric administration. Permeability was high in dogs with a variety of naturally acquired small intestinal diseases including wheat-sensitive enteropathy of Irish Setters, small intestinal bacterial overgrowth, and giardiasis, and permeability was decreased after successful treatment. These findings indicate that the assessment of intestinal permeability may be a useful technique for detecting small intestinal disease and for monitoring the efficacy of treatment in dogs.
