1-Kestose is a trisaccharide prebiotic that modifies immune responses in humans and rodents with allergic diseases by altering the intestinal microbiota. In present study, we examined effects of 1-kestose supplementation on microbiota, peripheral lymphocyte subsets, antibody production healthy dogs. Fecal IgA levels serum titers against rabies vaccine were not significantly affected supplementation. flow cytometric analysis, percentage T cells among total lymphocytes decreased, whereas B...
