In a five-day period, dermatitis developed in nearly one fourth of the guests staying at a large Georgia hotel. Dermatitis was associated with use of the hotel's whirlpool (p less than 0.001) and indoor swimming pool (p less than 0.001). Attack rates were highest among persons more frequently exposed to the whirlpool, in persons under 10 years of age, and during periods of heaviest bather load. Pseudomonas aeruginosa was isolated from skin lesions of 13 of 20 patients from whom culture specimens were taken. Ten isolates were serotype 0:9. The whirlpool's water grew P. aeruginosa serotype 0:9; however, the whirlpool's automatic chlorinator was functioning properly, the pH of the water was 7.2, and the free chlorine level was 0.6 mg/liter. This is the first report of a whirlpool-associated outbreak caused by P. aeruginosa serotype 0:9. Our findings suggest that this strain may not be readily sensitive to recommended chlorine concentrations.
在五天时间里，佐治亚州一家大型酒店近四分之一的住客患上了皮炎。皮炎与使用酒店的漩涡浴缸（p<0.001）和室内游泳池（p<0.001）有关。在更频繁接触漩涡浴缸的人群、10岁以下人群以及沐浴者流量最大的时段，发病率最高。从20例采集了培养标本的患者中的13例皮肤损伤处分离出铜绿假单胞菌。10株分离菌为血清型0:9。漩涡浴缸的水中生长出了血清型0:9的铜绿假单胞菌；然而，漩涡浴缸的自动加氯器运行正常，水的pH值为7.2，游离氯水平为0.6毫克/升。这是首例由血清型0:9铜绿假单胞菌引起的与漩涡浴缸相关的疫情报告。我们的研究结果表明，该菌株可能对推荐的氯浓度不敏感。
