- At autopsy, the most prominent findings were bronchopneumonia with focal organization and hemorrhage in the right lung. Stains of the lung tissue were negative by Gram, methenamine silver, and acid-fast methods, but Dieterle silver stains revealed short bacilli. Lung cultures yielded Gram-negative bacilli, which grew aerobically on buffered charcoal-yeast extract, but not on blood or chocolate agar. The organisms resembled Legionella, but failed to stain with immunofluorescence conjugates for Legionella pneumophila and multiple other species (L minded, L longbeachae, L gormanii, L dumoffi, L bozemanii). The organism was sent to the Centers for Disease Control and Prevention, where it was eventually identified as a new species of Legionella. What is the most probable source of this man's infection?
