摘　　要：自由生活阿米巴(Free-living amoebae,FLA)微生物近年来在饮用水系统中频繁被检出。FLA抗消毒能力较强,易在饮用水管网中定殖。除了自身致病性外,FLA可作为多种条件致病菌的宿主,给用户健康造成威胁。综述了饮用水系统中FLA的传播风险、FLA与抗阿米巴微生物(Amoeba-resistant microorganism,ARM)的相互关系及其分布特征,探讨了饮用水系统环境条件对FLA的影响及物理、化学和生物手段对其的控制措施,为饮用水系统中FLA监测及控制提供参考。Free-living amoebae(FLA)has been frequently detected in drinking water distribution systems.FLA has strong anti-disinfection ability and can easily colonize in drinking water systems.Besides the pathogenicity some species have,FLA can serve as hosts for a variety of bacterial opportunistic pathogens,posing severe health risks to drinking water consumers.This work reviewed the FLA potential health risks,interaction between amoeba-resistant microorganisms(ARM)and distribution characteristics in drinking water distribution systems.The influence of the environmental conditions of drinking water distribution system on FLA and its control measures by physical,chemical and biological methods were also discussed.This review provides insights to FLA monitoring and control in drinking water supply systems.
