Nocardial infection in a renal transplant recipient--a case report.

Report is given about a 50 year old renal transplant recipient who developed signs of a severe pneumonia 37 days post transplantation. The diagnosis following chest X-ray and physical examination was multifocal nodular pneumonia of unknown origin in an immunosuppressed patient. Although a varying antibiotic chemotherapy was administered at high doses he died 4 weeks later without identification of the infective agent. Post-mortem and microbiological examinations revealed a systemic suppurative infection caused by Nocardia asteroides. Percutaneous or open lung biopsy within the first 10 days after onset of clinical symptoms has to be recommended to secure the diagnosis and treatment with sulphonamides.
