Abstract

The article describes the pathomorphological macroscopic changes detected during the autopsy of piglets that died from the associative course of infectious pathology caused by Salmonella and Eimeria. In case of the associative course of salmonellosis and eimeriosis, three clinical forms of the disease were recorded: severe intestinal exicosis, an infectious-toxic form with a severe and very severe course, and a severe toxic-dystrophic form. During the course of the noted clinical forms, the animals showed signs of dehydration, acute catarrhal-fibrinous enterocolitis, hyperplasia of mesenteric lymph nodes, congestive hyperemia and granular degeneration of the liver and kidneys, milliary areactive dry necroses in the liver and kidneys, acute serous splenitis, chronic purulent and catarrhal bronchopneumonia, alveolar emphysema, alterative myocarditis, atrophy of the right ventricular myocardium, congestive hyperemia and cerebral edema.
