To assess the possible risk of microbial keratitis associated with swimming or bathing in public pools, the microbiological quality as well as the presence of free living amoebae in 16 halogenated swimming pools and whirlpools, located in Helsinki, Finland, was determined. Five additional whirlpools situated in the ferries cruising from Finland to Sweden were included in the study. Other parameters investigated were the total bacterial count, identification of Pseudomonas aeruginosa and Staphylococcus aureus, measurement of free residual and combined chlorine, potassium permanganate index, urine, pH, and turbidity. Amoebae were detected in 41% of the pool water samples studied. Seven of 11 whirlpools and four of 10 swimming pools were shown to contain amoebae. An Acanthamoeba species was isolated from only one outdoor swimming pool; the other amoebae belonged to the genera Vexillifera, Flabellula, Hartmannella, and Rugipes. Although not a single verified case of Acanthamoeba keratitis has been found in Finland, the findings show that there is a theoretical risk of amoebic and bacterial keratitis associated with swimming or bathing in properly cleaned public pools. Consequently, we do not recommend swimming or bathing with contact lenses.
为评估在公共泳池游泳或沐浴相关的微生物性角膜炎潜在风险，对位于芬兰赫尔辛基的16个加氯游泳池和漩涡浴池的微生物质量以及自由生活阿米巴的存在情况进行了测定。该研究还纳入了另外5个位于从芬兰到瑞典航行渡轮上的漩涡浴池。所调查的其他参数包括细菌总数、铜绿假单胞菌和金黄色葡萄球菌的鉴定、游离余氯和总氯的测量、高锰酸钾指数、尿液、pH值和浊度。在所研究的泳池水样中，41%检测到了阿米巴。11个漩涡浴池中7个以及10个游泳池中4个被证明含有阿米巴。仅从一个室外游泳池分离出一种棘阿米巴属；其他阿米巴属于Vexillifera属、Flabellula属、哈特曼氏阿米巴属和Rugipes属。尽管在芬兰尚未发现一例经证实的棘阿米巴角膜炎病例，但研究结果表明，在清洁得当的公共泳池游泳或沐浴存在阿米巴性和细菌性角膜炎的理论风险。因此，我们不建议戴隐形眼镜游泳或沐浴。
