Minimizing Legionella concentration in cooling water systems

摘要

term "Legionnaires' disease" was coined in 1976 after a respiratory disease outbreak among attendees at a convention in Philadelphia held by the American Legion of Pennsylvania. The bacteria was eventually isolated and officially named Legionella pneumophila. Legionella pneumophila is now associated with two separate illnesses: Legionnaires' disease and Pontiac fever. Legionnaires' disease is a severe pneumonia, while Pontiac fever is a mild influenza.
