The Legionella pneumophila bacteria are tagged with a monoclonal antibody treated with a fluorescein dye. After binding to the bacteria the slide is viewed under ultraviolet light, and the bacterial cell walls glow green. The early symptoms of avian influenza are remarkably similar to influenza (the "flu").  CT scan of chest showing consolidation of the left upper lobe (right side of image) from Legionnaire's disease.  Chest x-ray showing bilateral lower lobe infiltrates consistent with diagnosis of Legionnaire's disease.
