A 79-year-old man was admitted to hospital from his nursing home for treatment of pneumonia, but died 7 days after admission. Legionella pneumonia was diagnosed after isolation of Legionella pneumophila serogroup-5 from sputum culture. The environment of the nursing home was investigated; only water specimens from the 24-hour bath were positive by culture for Legionella pneumophila serogroup-5. Subsequent analysis by pulsed-field gel electrophoresis revealed an identical pattern in isolates from both sputum culture and 24 hour bath water culture. Among 123 inpatients and staff of the nursing home, 17 were found to be seropositive for Legionella pneumophila serogroup-5.
一名79岁男性从养老院入院治疗肺炎，但入院7天后死亡。痰培养分离出嗜肺军团菌血清型5后，诊断为军团菌肺炎。对养老院环境进行了调查；仅24小时沐浴用水标本经培养对嗜肺军团菌血清型5呈阳性。随后通过脉冲场凝胶电泳分析显示，痰培养和24小时沐浴用水培养分离株的图谱相同。在养老院的123名住院患者和工作人员中，发现17人嗜肺军团菌血清型5血清学阳性。
