The Requirement of Fibroblasts to Confirm the Identity of Cytogenetic Centric Fusion (CF) Carriers in Same-Sex Twin Cattle

Abstract

to demonstrate a tear or rupture. No evidence of thoracic trauma was found. The mucous membranes were pink, and there was no obvious pallor to the other body tissues. There were no other hemorrhages. No anticoagulant rodenticides were detected in the stomach contents or liver. Microscopic lesions were restricted to the tissue of the heart base and pericardium. Multiple lobules of thymic tissue were present at the heart base. There was depletion of lymphocytes and thinning of the cortex consistent with thymic invo1ution. Interlobular septa were markedly widened by hemorrhage (Fig. 1). This hemorrhage blended with hemorrhage infiltrating the wall of the dorsal pericardium, adventitia of the great vessels, and adipose tissue located at the heart base. Blood vessels in the medulla were heavily congested. Hemorrhages obscured the medulla of several lobules (Fig. 2).
