PATHOMORPHOLOGICAL AND PATHOGENIC CHARACTERISTICS OF VIRAL GASTROENTERITIS OF SWINE
Abstract
Conclusions: A disease of pigs, observed on a number of farms in the Ukraine, based on pathomorphological features, should be classified as acute desquamativecatarrhal gastroenteritis, often accompanied by superficial necrosis of the mucous membranes of the stomach and intestines. In contrast to gastroenteritis in pigs of another nature, a pathogenic peculiarity of this disease is that along with it, sharp functional changes on the part of the stomach and intestines are not accompanied by significantly expressed morphological changes of the mucous membranes, if the disease is not complicated by secondary infections. Judging by the pathomorphological changes in the stomach and intestines, the virus is apparently epithelialtropic. The sharp desquamation of the intestinal epithelium may explain the great contagiousness, since during profuse diarrhea a considerable dissemination takes place of the cells of the intestinal epithelim containing the causative agent of the disease into the surrounding medium.
