Cardio-histopathological observations on aborted equine fetuses infected with equid herpesvirus 1 (EHV-1)

摘要: Twenty-five aborted equine fetuses infected with equid herpesvirus 1 (EHV-1) were examined cardio-histopathologically. The main changes in the heart consisted of interstitial myocarditis and intramyocardial vascular lesions accompanied by degeneration necrosis cardiac myocytes. Vascular pathology small arteries arterioles was characterized endothelial cell fibrinoid media. Eosinophilic intranuclear inclusion bodies characteristic infection detected myocardial cells macrophages within around inflammatory medial smooth muscle damaged vessels. This observation, taken conjunction fact that EHV-1 antigens immunohistochemically some cells, provides morphological evidence support viral aetiology lesions.
