Nocardia farcinica lung infection in a patient with cystic fibrosis: a case report.

Introduction: Respiratory tract infections are the major causes of morbidity and mortality in patients with cystic fibrosis. Nocardia are rarely implicated in these infections and few reports of the involvement of this species are found in the literature.

Case Presentation: We describe a case of lung infection followed by chronic colonization of trimethoprim and sulfamethoxazole resistant Nocardia farcinica in a patient with cystic fibrosis.
