目的 了解我院供水系统(管道水)军团菌污染状况及其与医院内获得性肺炎患者军团菌感染状况相关性.方法 从我院病房大楼随机抽取管道水65份进行军团菌培养后,用军团菌分型诊断血清对军团菌进一步分型及对培养出的嗜肺军团菌血清1型(LP1)进一步鉴别临床株及环境株,同时对我院住院48 h后患肺炎的38例患者的痰或支气管肺泡灌洗液作军团菌培养,以及尿液军团菌抗原检测.结果 65份管道水中检出军团菌9株,阳性率为14%.其中嗜肺军团菌8株,占89%.LP1 6株,占67%,LP6、LP7各1株.非嗜肺军团菌米克戴德菌1株.所有LP1均为环境株;38份痰或支气管肺泡灌洗液经培养均无军团菌生长,所有尿抗原检测均为阴性.结论 我院管道水中存在军团菌污染,以LP1环境株为主.目前没有医院内获得性军团菌肺炎发生.加强对医院管道水中军团菌的监测,采取相应的防控措施,以防止医院内获得性军团菌病的暴发流行.
目的 瞭解我院供水繫統(管道水)軍糰菌汙染狀況及其與醫院內穫得性肺炎患者軍糰菌感染狀況相關性.方法 從我院病房大樓隨機抽取管道水65份進行軍糰菌培養後,用軍糰菌分型診斷血清對軍糰菌進一步分型及對培養齣的嗜肺軍糰菌血清1型(LP1)進一步鑒彆臨床株及環境株,同時對我院住院48 h後患肺炎的38例患者的痰或支氣管肺泡灌洗液作軍糰菌培養,以及尿液軍糰菌抗原檢測.結果 65份管道水中檢齣軍糰菌9株,暘性率為14%.其中嗜肺軍糰菌8株,佔89%.LP1 6株,佔67%,LP6、LP7各1株.非嗜肺軍糰菌米剋戴德菌1株.所有LP1均為環境株;38份痰或支氣管肺泡灌洗液經培養均無軍糰菌生長,所有尿抗原檢測均為陰性.結論 我院管道水中存在軍糰菌汙染,以LP1環境株為主.目前沒有醫院內穫得性軍糰菌肺炎髮生.加彊對醫院管道水中軍糰菌的鑑測,採取相應的防控措施,以防止醫院內穫得性軍糰菌病的暴髮流行.

Objective To investigate the relationship between contamination by Legionella in water supply system(potable water)and Legionella infection in patients with nosocomial pneumonia.Methods Sixty-five samples from potable water were collected and cultivated for Legionella.Slide agglutination test was used for identification of Legionella.The clinical and environmental strains of Legionella pneumophila serogroup 1(LP1)were identified.Legionella urinary antigen,sputum and bronchoalveolar lavage fluid (BALF)culture were used for the detection of Legionella in 38 patients with nosocomial pneumonia.Results Nine samples were contaminated by Legionella in 65 potable water samples.LP1,LP6 and LP7 were six,one and one isolate,respectively.Legionella micdadei was detected only one isolate.LP1 was all environmental isolate.Legionella urinary antigen,sputum and BALF culture were all negative in the detection.Conclusions The water supply system in the hospital is contaminated by Legionella.LP1 is the most common isolate.No case of hospital-acquired Legionella pneumonia has been found in the hospital by now.It can prevent the outbreak and epidemic of hospital-acquired Legionella pneumonia by monitoring Legionella in the potable water of hospital and taking preventive measures.
