Legionella Colonization of Hotel Water Systems in Touristic Places of Greece: Association with System Characteristics and Physicochemical Parameters.

This study aimed to assess the colonization of hotel water systems in central Greece and Corfu by , and to investigate the association between physicochemical parameters and colonization. Standardized hygiene inspection was conducted in 51 hotels, and 556 water samples were analyzed for spp Free chlorine concentration, pH, hardness, conductivity, and trace metals were defined in cold water samples. The results of inspections and chemical analyses were associated with the microbiological results using univariate and logistic regression analysis.

Clusters of Healthcare-Associated Legionnaires' Disease in Two Hospitals of Central Greece.

Healthcare-associated Legionnaires' disease often leads to fatal respiratory tract infection among hospitalized patients. In this report, three cases of Legionnaires' disease among patients in two different hospitals (Hospital A and Hospital B) were investigated. After conducting an epidemiologic and environmental investigation, the water distribution systems (WDSs) were identified as the possible source of infection, as serogroup 1 (1) was isolated from both clinical and environmental samples.
