由地下水供应的饮用水 在分配给消费者之前，水井通常不经过处理。 最近在亚利桑那州 非氯化饮用水和福氏纳氏菌 感染表明头部浸泡在非氯化溶液中 水源可能导致病毒传播 有机体。本文介绍的研究 这篇文章是为了确定事件的发生 在亚利桑那州的饮用水井中发现了N.fowleri。这个 这项研究的结果是N.fowleri 在10.6%的研究井中检测到。 供水供应商应考虑监测 wells为Naegleria fowleri的存在，尤其是 在水域较温暖的州。 如果发现了这种生物， 公用事业应考虑在分配之前对这些水域进行处理。 提高公共卫生保护水平 因为在未经治疗的情况下，这种病原体的存在 井水可能对公众健康构成威胁。包括24个参考文献、表格和图表。

Drinking water that is supplied from groundwater wells is often not treated before distribution to consumers. The recent association in Arizona between nonchlorinated drinking water and Naegleria fowleri infection suggests that head immersion in a nonchlorinated water source could lead to transmission of the organism. The study that is presented in this article was undertaken to determine the occurrence of N. fowleri in drinking water wells in Arizona. The outcome of the research was that N. fowleri was detected in 10.6% of the wells studied. Water suppliers should consider monitoring their wells for the presence of Naegleria fowleri, particularly in states with warmer waters. If the organism is found, utilities should consider treating such waters prior to distribution to increase the level of public health protection because the presence of such a pathogen in untreated well water may pose a public health threat.
