Pneumonia attributed to this organism, formerly called TATLOCK, HEBA (1), and "Pittsburgh pneumonia agent"(2), has been reported previously only in 13 immunosuppressed patients (3, 4).Thirty-seven patients admitted with pneumonia and 38 control subjects (patients with pulmonary disease or a presenting complaint of cough who did not have pneumonia) were studied. None were receiving steroids or immunosuppressive therapy. Bacteriologic data were obtained as part of their routine care in the hospital. Single or...References1.
