  • Title: Inhibition of small-intestinal sugar and amino acid transport by the enterotoxin of Shigella dysenteriae I.
    Author: Binder HJ, Whiting DS.
    Journal: Infect Immun; 1977 May; 16(2):510-2. PubMed ID: 324910.
    Abstract:
    The enterotoxin of Shigella dysenteriae I produces fluid and electrolyte secretion in the rabbit ileum. These present studies were designed to evaluate nonelectrolyte transport in rabbit ileal mucosa exposed to Shigella enterotoxin. Both 10 mM galactose and 5 mM L-alanine absorptions were significantly impaired in enterotoxin-exposed ileal mucosa compared with control mucosa. L-Alanine influx was not imparied in two other secretory processes: that induced by cholera enterotoxin and hyperosmolarity. These studies provide evidence that both surgar and amino acid absorptions are diminished in the small intestine by the enterotoxin of S. dysenteriae I.
