Images of Legionnaires' disease, which are suffused in ultraviolet light are posted on the Center for the Book of the Library of Congress as part of the Pennsylvania State University Libraries and Skinsight. Chest X-ray scans that aid in the diagnosis of the disease are also available at Skinsight and the official website of the Occupational Safety and Health Administration, or OSHA.
Legionnaires' disease, also known as Legionellosis, is a medical condition that affects the upper respiratory tract, particularly the lungs. The bacterium Legionella pneumophila has been identified as the carrier of the disease. OSHA includes a black and white image of the bacterium. Skinsight also presents a CT scan image of the chest that shows coalescence of the left upper lobe due to Legionnaires' disease.
