摘　　要：目的了解深圳市公共场所水系统嗜肺军团菌污染情况。方法 2012年10月-2013年10月随机采集本市41家公共场所冷却水、冷凝水、淋浴水、自来水、泳池水共194份水样按照《公共场所集中空调通风系统卫生规范》附录B方法进行检测嗜肺军团菌及其菌型。结果嗜肺军团菌阳性率冷却水为46.2%(32/69)、自来水为42.3%(22/52)、淋浴水为34.6%(18/52),冷凝水、泳池水未检出嗜肺军团菌;嗜肺军团菌冷却水阳性率在酒店宾馆为54.2%(13/24)、商场为36%(9/25)、候诊室为62.5%(5/8)、地铁站为41.7%(5/12),场所间差异无统计学意义(χ2=2.611,P=0.455);分离出79株嗜肺军团菌菌型以Lp1型为主,占68.1%(47/79),Lp3型占24.1%(19/79)、其他菌型占16.5%(13/79)。结论本市公共场所空调冷却水、生活用水中自来水、淋浴水均存在嗜肺军团菌污染,应加强空调系统和生活用水的清洗消毒。Objective To investigate the situation of Legionella pneumophila pollution in the water systems of public places in Shenzhen City. Methods A total of 194 water samples were randomly collected from cooling water, condensate water, show- er water, tap water and swimming pool water of 41 public places in Shenzhen City, and then Legionella pneumophila and bacte- rial type were tested according to the appendix 13 in Hygienic Specification of Central Air Conditioning Ventilation System in Public Buildings. Results The detection rates of Legiondla pneumophila in cooling water, tap water and shower water were 46.2% （32/69）, 42.3% （22/52） and 34.6% （18/52） respectively. No Legionella lmeumophila was detected from con- densate water and swimming pool water. The detection rates of Legionella pneumophila in cooling water of hotels, shopping malls, waiting rooms and subway stations were 54.2% （13/24）, 36% （9/25）, 62.5% （5/8）, 41.7% （5/12）, and no statisti- cally significant difference was found among the different sites （χ2 = 2.611, P = 0. 455）, Of the 79 strains of Legionella lrneu- mophila isolated, Lpl, Lp3 and other bacterial types accounted for 68.1% （47/79）, 24, 1% （19/79） and 16.5 % （13/79） re- spectively. Conclusions Air conditioning cooling water, tap water and shower water of the public places in Shenzhen City have been contaminated with Legionella pneumophila ; and hence, it is necessary to strengthen the cleaning and disinfection of air conditioning system and domestic water.
