HISTOPATHOLOGICAL CHANGES AT OF THE MIXED PASTEURELLOSIS AND ASCARIDOSIS DISEASE OF POULTRY DURING THE ACUTE AND CHRONIC COURSE

The article presents the results of histological studies of the endocrine glands and parenchymal organs of dead poultry at of the mixed pasteurellosis and ascaridosis disease during the period of acute and chronic course. It was found that the histopathological changes registered with the mixed pasteurellosis and ascaridosis disease play an important role in setting the final diagnosis and differential diagnosis. Substantial pathological changes in internal organs of poultry at of the mixed pasteurellosis and ascaridosis disease was observed in the heart (focal myocardial necrosis, the grainy and fatty degeneration of the muscle fibers, loss of striation and the fragmentation); of the liver (hepatocytes were in a state granular dystrophy, the blood vessels filled with blood); the duodenum (a catarrhal-hemorrhagic inflammation). Found that the most pronounced histopathological changes were among chickens with acute course the mixed of disease and were characterized by focal myocardial necrosis, granular dystrophy of the liver, catarrhal-hemorrhagic enteritis, catarrhalhemorrhagic duodenitis and amyloid deposition in the glomerular capillary loops and beneath the basement membrane of kidney tubules
