Pseudomonas aeruginosa was isolated from seven commercial and two residential whirlpools that were treated with halogens. None of the commercial whirlpools was constantly maintained at appropriate disinfection levels. Superchlorination or the draining, cleaning, disinfection, and refilling of whirlpools markedly reduced densities of P. aeruginosa in whirlpool water, but the bacterial populations were rapidly reestablished (less than 10(3) cells per ml) when disinfectant concentrations decreased below recommended levels (chlorine, 3.0 ppm [3.0 micrograms/ml]; bromine, 6.0 ppm). P. aeruginosa in the water was replenished from various sources, such as hoses used to fill the whirlpool and the biofilm in the filter and piping of the whirlpool systems. Daily monitoring and adjustment of chemical characteristics (regardless of bather load) were essential for controlling densities of P. aeruginosa.
从七个商业用和两个家用的经卤素处理的漩涡浴池中分离出了铜绿假单胞菌。没有一个商业漩涡浴池能持续维持在适当的消毒水平。对漩涡浴池进行超氯消毒或排水、清洁、消毒和重新注水，可显著降低漩涡浴池中铜绿假单胞菌的密度，但当消毒剂浓度降至推荐水平以下（氯，3.0 ppm [3.0微克/毫升]；溴，6.0 ppm）时，细菌数量会迅速重新建立（每毫升少于10³个细胞）。水中的铜绿假单胞菌可从各种来源补充，如用于填充漩涡浴池的软管以及漩涡浴系统过滤器和管道中的生物膜。每日监测和调整化学特性（无论沐浴者数量）对于控制铜绿假单胞菌的密度至关重要。
