摘　　要：目的掌握石家庄市水体环境病原菌分布状况,评价可能存在的安全风险。方法于2013年1—12月采集该市自备井水、二次供水、出厂水、直饮水、医疗机构污水、游泳池水、景观水、集中空调系统冷凝水水样进行病原菌分离和鉴定。结果共采集346件水样,检出53种细菌。阴沟肠杆菌、铜绿假单胞菌、嗜水气单胞菌、弗氏柠檬酸杆菌、肺炎克雷伯菌、大肠埃希菌的检出率较高,依次为24.0%(83/346),22.8%(79/346),15.3%(53/346),13.3%(46/346),12.1%(42/346),12.1%(42/346)。结论水体环境中占优势的为条件致病菌,其在水域、季节上的分布存在差异。Objective To master the pathogens distribution and potential risks in water environment of Shijiazhuang city. Methods From January to December in 2013, a total of 346 water samples were collected, including self-supplied wells water, two pressurized water,finished water,drinking water,sewage in medical institution,swimming pool water,landscape water, condensation water of air conditioning system. Pathogens were isolated and identified from the water. Results A total of 53 kinds of bacteria were detected. The dominant bacteria were Enterobacter cloacae,Pseudomonas,Aeromonas hydrophila, Citrobacterfreundii,Klebsiella pneumoniae and Escherichia coli, and the detection rates were 24.0% （83/346）,22.8% （79/ 346）, 15.3% （53/346）, 13.3% （46/346）, 12.1% （42/346） and 12.1% （42/346） respectively. Conclusion In the water environment of Shijiazhuang,the opportunistic pathogens are dominant. There are distribution differences of pathogens in different seasons and different water environments.
