Abstract

This report focuses on the diagnostic laboratory and necropsy findings in 4 llamas with adenovirus-associated hepatitis or pneumonia. In the 2 young llamas, clinical illness was characterized by chronic respiratory tract disease. In the 2 adult llamas, clinical illness was characterized by neurologic signs and a history of respiratory tract disease. Histologic examination, electron microscopy, virus isolation, and fluorescent antibody results indicated that adenovirus infection was associated with disease in all 4 llamas.
