【摘要】 一类新型的饮用水致病菌——条件致病菌,已成为饮用水相关介水传播疾病暴发的重要病原之一。条件致病菌能在管道系统贫营养饮用水环境中再生长,具备耐热、抗消毒剂能力,并可通过呼吸吸入、皮肤接触等方式侵入人体。饮用水系统是条件致病菌感染人体的主要途径。简要介绍了饮用水输配水系统中条件致病菌的检出情况和致病风险,并对影响饮用水系统中条件致病菌再生长的关键因素(例如水温、消毒剂、管材、生物因素)进行了深入讨论,并分析了控制条件致病菌风险的相关措施。更多还原

【Abstract】 A new type of pathogenic bacteria in drinking water,e. g. opportunistic pathogens( OPs),represent an emerging drinking water related waterborne disease problem worldwide. These microorganisms can naturally reestablish in drinking water systems featured with poor nutritious environment,and have capabilities of heat and disinfectant resistances. Inhalation of aerosols and direct contact are the primary transmission routes for OPs,which can occur during drinking water consumption. The current knowledge of OPs detection and potential health risks in drinking water distribution systems were introduced. The key factors affecting OPs regrowth in drinking water systems,such as temperature,disinfectants,pipe materials,and biofilms were thoroughly discussed. Finally,measures for controlling OPs were critically evaluated.更多还原
