Fatal nosocomial Legionella pneumophila infection due to exposure to contaminated water from a washbasin in a hematology unit.

摘要

A fatal nosocomial infection with Legionella pneumophila serogroup 5 occurred in a patient with leukemia. Isolates recovered from both the potable water supply and the patient showed an identical genomic profile. With no other exposure identified, the water from the washbasin was evidently the source of infection.
