Lung infection caused by Nocardia asteroides in a renal-transplant patient

A 65-yr-old man developed an acute lung infection while being treated for a rejection episode 2 months after renal transplantation. A chest X-ray revealed a pulmonary infiltrate. Nocardia asteroides was cultured from a percutaneous lung aspirate. The patient was successfully treated with trimethoprim/sulfamethoxazole.
