title: Legionella feeleii serotype 2 pneumonia in a man with chronic lymphocytic leukemia: a challenging diagnosis.
abstract: Legionella feeleii has rarely been reported as causing pneumonia in patients with hematologic malignancies. We present a case of Legionella feeleii serotype 2 pneumonia with empyema in a man with chronic lymphocytic leukemia and describe the methods of identifying this organism using both standard methods and newer diagnostic techniques.
