Neuritis cordis and myocarditis in rabies

Once the rabies virus has spread through the central nervous system (CNS), the virus is also transported centrifugally along axons, especially of the autonomic nervous system, to a wide range of organs including the heart. In this case report of a 49-year-old man who had been bitten by a dog in Asia, the rabies infection of cardiac nerves and cardiac muscle fibres is shown by immunohistochemistry. The neuritis cordis and rabies myocarditis can have important clinical effects on the heart rate and myocardial function and lead to blood pressure crises which are typical for the clinical course of rabies in humans.
