We describe herein the clinical features, diagnosis, and successful treatment of two patients with Legionella micdadei pneumonia, the Pittsburgh pneumonia agent. The rapid pulmonary cavitation and relapse of symptoms after a course of therapy in a renal transplant recipient, and the prolonged illness with hemorrhagic pleural fluid, splenomegaly, and multipleorgan dysfunction in a nonimmunocompromised host, illustrate the clinical spectrum of infections with this organism.
