In addition to Legionella pneumophila, about 20 Legionella species have been documented as human pathogens. The majority of infections by non-pneumophila Legionella species occur in immunocompromised and splenectomized patients. Here, we report a case of classical lobar pneumonia caused by Legionella longbeachae in a splenectomized patient receiving corticosteroids for chronic immune thrombocytopenia. Tests for Legionella antigen were negative. L. longbeachae was immediately detected in bronchoalveolar fluid by PCR and subsequently confirmed by culture on legionella-selective media. The features of Legionnaires' disease in immunocompromised patients with special emphasis on significance and detection of non-pneumophila species are reviewed.
