Abstract：
Pseudomonas aeruginosa is a major opportunistic human pathogen commonly connected with recreational water activities. Spain is a tourist destination where most of the establishments have swimming pool. Nevertheless, the prevalence of P. aeruginosa in public swimming pools in our country is unknown. This works aimed to survey the P. aeruginosa presence in tourist Spanish recreational waters.
Tourist recreational water in hotels in the Balearic Islands were visited for four years (2016-2019). The levels of selected parameters were determined, and their correlation with P. aeruginosa contamination investigated.
We evaluated 11,014 samples from 254 facilities. Unacceptable levels of at least one legislated parameter were detected in 30.7% of cases, implicating closure in 15.9%, being P. aeruginosa the leading cause of closure. The prevalence of the pathogen was 14.2%, with lower presence in outer swimming pools. Disinfectant levels influence P. aeruginosa contamination, and bromine-maintained pools were more often contaminated than those treated with chlorine. Prevalence remained constant over the years, although it increased in 2019.
P. aeruginosa prevalence in our recreational waters is similar to other countries, and the contamination rates depend on the installations and type and disinfectant levels. Corrective measures are still needed to improve pathogen control.

摘要：
背景：铜绿假单胞菌是一种主要的机会性人类病原体，通常与娱乐性水活动有关。西班牙是一个旅游胜地，大多数场所都有游泳池。然而，我国公共游泳池中铜绿假单胞菌的患病率尚不清楚。这项工作旨在调查西班牙旅游休闲水域中铜绿假单胞菌的存在。
方法：参观了巴利阿里群岛酒店的旅游休闲水四年（2016-2019年）。确定了选定参数的水平，以及它们与铜绿假单胞菌污染的相关性。
结果：我们评估了来自254家工厂的11,014个样本。在30.7%的病例中检测到至少一个法定参数的不可接受水平，牵涉到15.9%的闭合，铜绿假单胞菌是关闭的主要原因。病原体的患病率为14.2%,在外游泳池中存在较少。消毒剂水平影响铜绿假单胞菌污染，与用氯处理的池相比，溴保持池受到的污染更多。患病率多年来一直保持不变，虽然在2019年有所增加。
结论：P.我们休闲水域的铜绿假单胞菌患病率与其他国家相似，和污染率取决于安装和类型和消毒剂水平。仍然需要采取纠正措施来改善病原体控制。
