Extensive visceral lesions containing intranuclear inclusions have been produced in mice by intraperitoneal and intracerebral inoculations of the homologous salivary gland virus. Rarely small pancreatic lesions containing inclusions have been encountered 2 weeks after subcutaneous inoculation.

In spite of the extensive lesions produced in the liver and spleen, the virus could not be transferred with an emulsion of these organs.
