1976 Philadelphia Legionnaires' disease outbreak killed 16 persons out of 78 infected was later determined to be Legionnaires' disease. A September 1974 convention of the Independent Order of Odd Fellows was also held at the Bellevue-Stratford Hotel. Out of approximately 1,500 members who attended, 20 developed pneumonia and two died. A later article in "The Lancet" reported: "Illness [high fever and pneumonia] was significantly associated with attendance at one convention activity held on Monday morning, September 16, 1974, in the grand ballroom of the hotel." 1976 Philadelphia Legionnaires' disease outbreak The 1976 Legionnaires disease outbreak, occurring in the late summer in Philadelphia, Pennsylvania, was the
Legionella clemsonensis yellow. Legionella clemsonensis Legionella clemsonensis was isolated in 2006, but was discovered in 2016 by Clemson University researchers. It is a Gram-negative bacterium. “"Legionella"” is named after the American Legion convention where the first outbreak occurred, killing 34 people and sickening 221 individuals in 1976. It occurred in Philadelphia during the convention for the association of the U.S. veterans. The specific name "clemsonensis"” derives from Clemson University, where undergraduates DNA-sequenced this new strain. "Legionella" has a correlation with another genus called "Coxiella". Both cause lung infection that can eventually lead to pneumonia due to the intracellular bacteria in aerosols. Based
