Electricity-dependent hot-water tanks are widely used in the province of Quebec (Canada) and have been shown to be frequently contaminated with<jats:italic>Legionella<\/jats:italic>spp. We prospectively investigated the homes of culture-proven SCAL patients from Quebec in order to establish the proportion of patients whose domestic potable hot-water system was contaminated with the same<jats:italic>Legionella<\/jats:italic>isolate that caused their pneumonia. Water samples were collected in each patient's home. Environmental and clinical isolates were compared using pulsed-field gel electrophoresis. Thirty-six patients were enrolled into the study.<jats:italic>Legionella<\/jats:italic>was recovered in 12\/36 (33%) homes. The residential and clinical isolates were found to be microbiologically related in 5\/36 (14%) patients. Contaminated electricity-heated domestic hot-water systems contribute to the acquisition of SCAL. The proportion is similar to previous reports, but may be underestimated.<\/jats:p>","DOI":"10.1017\/s0950268811000355","type":"journal-article","created":{"date-parts":[[2011,3,14]],"date-time":"2011-03-14T11:36:01Z","timestamp":1300102561000},"page":"172-181","source":"Crossref","is-referenced-by-count":15,"title":["Sporadic Legionnaires' disease: the role of domestic electric hot-water tanks"],"prefix":"10.1017","volume":"140","author":[{"given":"S.
