Canine pneumocystis pneumonia.

This is a case report of pneumocytosis of an eight month old Dachschund from the Cape Province. Clinically it was an afebrile disease with signs limited primarily to the lower respiratory tract. The report consists of a short history, the histopathologic findings, evidence of the electron microscopic confirmation of the diagnosis and a brief discussion. It is believed to represent the first case of canine pneumocystosis in the Republic of South Africa.
