Diarrhea is the main clinical manifestation of enteric infections. Imbalance between absorption and intestinal secretion process due to changes in the water and electrolytes transport is critical in the diarrheal diseases pathogenesis. The pathophysiological mechanisms are associated to specific characteristics of each pathogen. Therefore, specific interaction between enteric pathogens and intestinal epithelium result in different types of diarrhea. In swine production, the knowledge about the enteric infections pathophysiology is important for the development of diagnostic methods and, in a near future improvement of prevention and control strategies. The aim of this review is to describe different relevant aspects of the swine diarrhea pathophysiology based on the physiological processes typical of gastrointestinal tract. Pathological changes in the intestinal transport of ions and nutrients due to infectious relevant for swine production will be emphasized.
