1976年7月,美国退伍军人协会宾夕法尼亚州分会在费城一旅馆举行58届年会。在大部分与会者中暴发1次著名的急性肺炎流行,221例病人有34例死亡。当时因病因不明,暂称为军团病(Legionnaires disease,也有译为退伍军人病)。后经美国疾病控制中心研究,证明为一属新的细菌——嗜肺性军团病杆菌(Legionella pneumophilla)感染所致。1977年,对1968年7月称为庞提阿克热(Pontiac feves)的血清再进行检测,发现了嗜肺性军团病杆菌抗体,从而证实庞提阿克热和军团病系由同一属细菌所致的不同综合征。此后美国各州和许多国家相继有疫情报告,在国外引起了广泛重视。
In July 1976, the Pennsylvania Legion of the American Veterans’ Association held its 58th annual meeting at a Philadelphia hotel. One well-known outbreak of acute pneumonia was reported among the majority of participants, with 34 of 221 patients dying. At that time due to unknown etiology, tentatively called Legionnaires disease (Legionnaires disease, also translated as veterans disease). After the United States Centers for Disease Control study, proved to be a new bacterium - Legionella pneumophila infection (Legionella pneumophilla) due. In 1977, another sero-strain of Legionella pneumophila was detected in a blood test called Pontiac feves in July 1968, confirming that the pontiac fever and Legionnaires’ disease were caused by the same genus of bacteria Due to the different syndromes. Since then, the U.S. states and many other countries have successively reported the epidemic and have drawn wide attention abroad.
