【摘要】：目的了解厦门市公共场所水系统中军团菌的污染状况,为军团菌病的预防和控制提供依据。方法参照《公共场所集中空调通风系统卫生规范》,2009年-2015年逐步采集公共场所二次供水系统的水塔水及集中空调系统的冷却水和冷凝水,检测军团菌及其血清型。结果 2009年冷却水、水塔水军团菌的检出率分别为41.5%(17/41)、17.6%(6/34),两者差异有统计学意义(χ~2=4.96,P0.05)。2012年冷却水军团菌检出率为50.0%(11/22)。2014年冷却水、冷凝水军团菌的检出率分别为22.7%(5/22)、13.0%(3/23),差异无统计学意义(χ~2=0.21,P0.05)。2010年、2011年、2013年、2015年均未检出军团菌。分离出的菌株以Lp1型(57.4%)嗜肺军团菌为主,其次为Lp5(17.0%)和Lp7(12.8%)。结论应加强监督监测,定期清洗消毒,降低公共场所水系统滋生军团菌的风险。
[Abstract]:Objective to understand the pollution of Legionella in the water system of public places in Xiamen, and to provide the basis for the prevention and control of legionellosis. Methods referring to the hygienic specifications of ventilation system in public places, we collected the cooling water and condensed water of the two water supply system and the central air conditioning system in public places in 2009 -2015, and detected Legionella and serotype. Results the detection rate was 41.5% in 2009, the Navy cooling water tower Legionella (17/41), 17.6% (6/34), the difference was statistically significant (~2=4.96, P0.05). In 2012 of Legionella pneumophila in cooling water of the detection rate was 50% (11/22). Cooling water and condensed water in 2014 detection of Legionella rate were 22.7% (5/22), 13% (3/23), the difference was not statistically significant (~2=0.21, P0.05). Legionella was not detected in 2010, 2011, 2013, and 2015. The isolated strains were mainly Legionella pneumophila type Lp1 (57.4%), followed by Lp5 (17%) and Lp7 (12.8%). Conclusion supervision and monitoring should be strengthened, regular cleaning and disinfection are necessary to reduce the risk of Legionella in the water system in public places.
