Persistent nocardemia following renal transplantation. Association with pulmonary nocardiosis.

Pulmonary nocardiosis occurred in a renal homotransplant patient and was diagnosed by persistently positive blood cultures. Infection developed at a time when efforts were being made with moderate dosages of immunosuppressive drugs to prevent rejection of the transplant. The subsequent nocardemia lasted for one week. The remaining kidney function was preserved, and the patient had a very favorable outcome because of early diagnosis and prompt treatment with sulfisoxazole.
