In September and October 1981 six cases of pneumonia occurred among men working in a power station under construction. Three were identified as cases of legionella pneumonia and two others had serology suggestive of legionella infection. In a sample of 92 men from the site 10 had low levels of antibodies to legionella; a similar sample of men working on an adjacent site showed none with positive serology. In a case control study it was found that cases of pneumonia were more likely than controls to have worked on a part of the site where four small capacity cooling towers were located. Legionella pneumophila serogroup 1 was isolated from the water systems of these four towers but was not found in samples from any other cooling towers or hot or cold water outlets on the site. It would appear that there was airborne spread of the organism from these cooling water systems which had not received conventional treatment to inhibit corrosion and organic growth. This is the first outbreak of legionnaires' disease to be recorded in an industrial setting in the United Kingdom. No cases of legionella infection have occurred on the site since the introduction of control measures.
1981年9月和10月，在一座在建发电站工作的男性中出现了6例肺炎病例。其中3例被确诊为军团菌肺炎，另外2例血清学检查结果提示军团菌感染。在该工地的92名男性样本中，10人对军团菌的抗体水平较低；在相邻工地工作的男性的类似样本中，血清学检查呈阳性的人一个都没有。在一项病例对照研究中发现，与对照组相比，肺炎病例更有可能在工地中设有4个小容量冷却塔的区域工作。从这4个冷却塔的水系统中分离出了嗜肺军团菌血清1型，但在该工地的任何其他冷却塔或冷热水出口样本中均未发现。看起来该病原体是从这些未经过抑制腐蚀和有机物生长的常规处理的冷却水系统经空气传播的。这是英国工业环境中首次记录的军团病暴发。自采取控制措施以来，该工地未再出现军团菌感染病例。
