Acute murine adrenalitis induced by reovirus 3. An ultrastructural study.
Reovirus 3 infection of neonatal mice, although characterized primarily by encephalitis, hepatitis, and pancreatitis, also induces an adrenalitis. Histologically, the latter is characterized initially by foci of coagulative necrosis which later enlarge and become surrounded by leukocytic infiltration. Ultrastructurally, the virus was shown to replicate in the paranuclear region of mainly adrenocortical cells but also medullary and endothelial cells. Apoptosis is the most common form of necrosis exhibited and is quickly followed by an infiltration of mononuclear phagocytes which eventually ingest the virus and the cellular debris.
