The aim of the present study was to determine the prevalence of Legionella spp. in water systems of hospitals and hotels located in South Western Greece, to study the molecular epidemiology of the isolated strains and their possible association with bacterial contamination (total count and Pseudomonas aeruginosa), the water pH, and temperature. A prevalence survey for Legionella spp. by culturing techniques in water distribution systems of eight hospitals and nine hotels occurred in South Western Greece. Water sampling and microbiological analysis were carried out following the ISO methods. Legionella pneumophila was detected in 33% and 36% of the distribution systems of hospitals and hotels, respectively. Our survey results suggest a frequent prevalence of elevated concentrations of Legionella spp. in water systems of hospitals and hotels. Our investigation has confirmed the need to regularly monitor the microbiological condition of water systems in hospitals and hotels.
本研究旨在确定南希腊地区医院和酒店供水系统中军团菌属的流行情况，研究分离菌株的分子流行病学及其与细菌污染（总计数和铜绿假单胞菌）、水的 pH 值和温度的可能关联。采用培养技术对南希腊地区 8 家医院和 9 家酒店的供水系统进行了军团菌属流行情况调查。水样采集和微生物分析按照 ISO 方法进行。分别在 33%和 36%的医院和酒店的供水系统中检测到嗜肺军团菌。本调查结果表明，医院和酒店供水系统中军团菌属的浓度经常偏高。本研究证实，有必要定期监测医院和酒店供水系统的微生物状况。
