Porcine Salmonellosis

Abstract
Hemorrhagic necrosis of the gastric and colonic mucosa with capillary thrombosis were induced in pigs experimentally infected with Salmonella cholerae-suis when an additional intravenous supply of disintegrated cells of Salmonella cholerae suis or hemolytic Escherichia coli was administered. Except for the gastrointestinal lesions, the necropsy findings were almost identical with the picture found in acute septicemic salmonellosis. The gastrointestinal changes were interpreted as a special gastroenteric effect of endotoxins of Gramnegative bacteria during the development of septicemic salmonellosis.
