An electric utility screened 1,455 production employees for job exposure to Legionella pneumophila sources, illness history, and antibodies to L pneumophila serotypes I-IV. L pneumophila-associated illness outbreaks had occurred in a neighboring electric utility district; bacteria serocompatible with L pneumophila had been detected in all four plants participating in an environmental survey, and the company was concerned about the implications of these findings for their employees and the public living near power plants with large cooling towers. The survey revealed a prevalence of antibodies in employees consistent with general population surveys. Within the employee group, antibody titer was not associated with either reports of recent illness or work exposure to potential L pneumophila sources. Inability to detect a relationship between exposure to potential L pneumophila sources and specific antibody results was used to define L pneumophila as a historic nonproblem for this company and to rationally advise against the need for an ongoing screening program.
一家电力公司对1455名生产员工进行了筛查，以了解他们接触嗜肺军团菌源的工作情况、病史以及针对嗜肺军团菌血清型I-IV的抗体情况。在邻近的一个电力公司辖区曾发生过与嗜肺军团菌相关的疾病暴发；在参与环境调查的所有四家工厂中都检测到了与嗜肺军团菌血清型相符的细菌，该公司担心这些发现会对其员工以及居住在有大型冷却塔的发电厂附近的公众产生影响。调查显示，员工体内抗体的流行情况与一般人群调查结果一致。在员工群体中，抗体滴度与近期疾病报告或接触潜在嗜肺军团菌源的工作情况均无关联。由于无法检测到接触潜在嗜肺军团菌源与特定抗体结果之间的关系，因此将嗜肺军团菌定义为该公司过去存在的一个问题，并合理建议无需开展持续的筛查项目。
