Dermatitis in sheep in Mosul area

Abstract

Dermatitis in (25) sheep showing different distribution of the lesions were classified pathologically to acute, subacute, and chronic dermatitis. Grossly, the lesions were characterized by alopecia, erythema, exudation, ulceration, scale and crust formation. Histopathological sections revealed degeneration, spongiosis, intercellular edema with diffuse leukocytic infiltration predominantly neutrophils, lymphocytes and eosinophils in the dermal layer of the skin. The lesions were more progressive in chronic dermatitis.

Pathomorphological Study of Liver Lesions in Sheep at Duhok Abattoir

“…As for what was noticed from the presence of congestion and hemorrhage visually, this necessarily leads to damaging the liver and this is consistent with what watched by some authors [27], but the results of the research differ in the percentage rate of these lesions it was recorded 2.2% and these are might be due to old lesion as chronic inflammation and fibrosis [28], also it was found to be occur frequently in sheep belonging to many of toxic agents through ingestion of environmental toxicants or plants during seasonal period of years. The chronic venous congestion of liver occurs commonly due to stagnation of blood within the central vein and adjacent sinusoids with subsequent necrosis of peripheral hepatocytes because of hypoxia.…”
