- 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? Family member Water Food Insect Bioterrorism Dark-field microscopy may be used to diagnose spirochetes in which of the following scenarios? To detect spirochetes in the blood of a…What is this organism? And what other test could be done to confirm it's identification? 1.Gram stain - positive cocci, chains Catalase - weak positive Hemolysis - beta BE - positive NaCl- positive Bacitracin - no zone of inhibition PYR - positive Answer: Enterococcus spp. CAMP test to verify the identity 2.Gram positive cocci, chains Catalase - negative Hemolysis - alpha BE - negative NaCl - negative P disk - resistant Bile Solubility - negative Answer - viridans group, Use PYR test to verifyIdentify: 1.
