Legionella pneumophila is a motile, rod-shaped, gram-negative, aerobic, bacterium. It is considered to be a "facultative parasite," which in the last twenty years has been identified as the leading cause of Legionnaire's Disease. This disease was first discovered in 1976 among a group of elderly men attending an American Legion Convention in Philadelphia, Pennsylvania1 (hence the name Legionnaire's Disease). When this outbreak first occurred it shocked the nation and the world, because no one knew why all of the men at the convention were being diagnosed with with acute respiratory failure. However now, more than twenty years later, scientists have learned a great deal about Legionnaire's Disease, as well as the Legionella pneumophila the pathogen which causes it.
