PY - 2019 T2 - Jawetz, Melnick, & Adelberg’s Medical Microbiology, 27e AB - A widely publicized outbreak of pneumonia in persons attending an American Legion convention in Philadelphia in 1976 prompted investigations that defined Legionella pneumophila and the legionellae. Other outbreaks of respiratory illness caused by related organisms since 1947 have been diagnosed retrospectively. Several dozen species of Legionella exist, some with multiple serogroups. L pneumophila is the major cause of disease in humans; Legionella micdadei and a few other species sometimes cause pneumonia. The other legionellae are rarely isolated from patients or have been isolated only from the environment.
