- Why is glucose not the choice of carbohydrate for most differential media used in the identification of gram (-) enteric bacilli?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?
