来自弗吉尼亚州安娜湖的水被用于冷却核电站的反应堆和娱乐活动，被评估为福氏耐格里虫的存在，福氏耐格里虫是一种引起原发性阿米巴脑膜脑炎（PAM）的阿米巴。进行这项调查是因为据报道，热富集水促进N的传播。因此，fowleriand增加了人类感染的风险。在2007年夏天的16个采样点中，有9个被发现对N呈阳性。Fowleri通过巢式聚合酶链反应测定。然而，总阿米巴计数，包括N。fowleri，从未超过12/50毫升的湖水在任何网站。电导率、溶解氧、温度和水的pH值与N的存在之间没有相关性。福勒里迄今为止，PAM的情况下，还没有报告从这个热富湖。据推测，其他原生动物和无脊椎动物的捕食，娱乐性划船活动对水面的干扰，或细菌或真菌毒素的存在，维持了N的数量。福勒在安娜湖的水位很低。
Water from Lake Anna in Virginia, a lake that is used to cool reactors at a nuclear power plant and for recreational activities, was assessed for the presence ofNaegleria fowleri, an ameba that causes primary amebic meningoencephalitis (PAM). This survey was undertaken because it has been reported that thermally enriched water fosters the propagation ofN. fowleriand, hence, increases the risk of infection to humans. Of 16 sites sampled during the summer of 2007, nine were found to be positive forN. fowleriby a nested polymerase chain reaction assay. However, total ameba counts, inclusive ofN. fowleri, never exceeded 12/50 mL of lake water at any site. No correlation was obtained between the conductivity, dissolved oxygen, temperature, and pH of water and presence ofN. fowleri. To date, cases of PAM have not been reported from this thermally enriched lake. It is postulated that predation by other protozoa and invertebrates, disturbance of the water surface from recreational boating activities, or the presence of bacterial or fungal toxins, maintain the numberN. fowleriat a low level in Lake Anna.
