The patient was diagnosed as nosocomial Legionella pneumonia by a polymerase chain reaction (PCR) from bronchoalveolar lavage and a culture of L. pneumophilaserogroup 2–14 from patient’s room faucet water. Legionella was eradicated from our hospital’s water distribution system by superheating and chemical eradication methods (hyper-chlorination and hydrogen peroxide). We did not detect any case after this event. Early recognition of contamination of hospital water system with Leigonella proves the importance of prevention new cases. ER -
