Ectopia cordis cervicalis holstein-fríz borjúban - Esetismertetés

Abstract

SUMMARY The authors report a histopathological investigation of the myocardium, aorta, truncus pulmonalis and lungs from a two-days-old Holstein Friesian bull calf carcass with ectpoia cordis cervicalis. The atriums showed hallmarks of myocardial hypertrophy, multifocal myodegeneration, multiplex interstitial and intramuscular acute haemorrhages; mild lympho(histio)cytic inflammation; interstitial oedema, furthermore right atrial interstitial fibrosis. The ventricles showed hallmarks of myocardial hypertrophy, mild perinuclear lipofuscin accumulation, multifocal myocardial vacuolisation, -lysis; multiplex interstitial, and intramuscular acute haemorrhages; mild lympho(histio)cytic inflammation; lymphangiectasia, interstitial oedema. In the pericardium, and myocardium they detected CD3-positive T-lymphocytes, and intact claudin-5-positive endothelium of the vessels. The walls of the aorta and truncus pulmonalis were intact. In the lungs multiple thrombosis/thromboembolisation, acute congestion, haemostasis, acute interstitial and intraalveolar haemorrhages, furthermore meconium-aspiration were detected. PCR-analysis was negative for BVD-, IBR-, Bluetongueand Schmallenberg viruses.
