Legionella pneumophila was found in the infected hemodialysis fistulas of two patients. The first patient developed an infection of the fistula during acute illness with Legionnaires' pneumonia. Legionella organisms were shown to be present in the graft by direct immunofluorescent staining. The second patient developed an infection of the hemodialysis fistula 3 weeks after completing a course of erythromycin therapy for Legionnaires' pneumonia. Legionella organisms were found by direct immunofluorescence in purulent material that was obtained from the graft, and serogroup 1 L. pneumophila was isolated from the pus. The frequency with which the organism causes infection of hemodialysis access sites is unknown. Increased awareness by physicians that L. pneumophila produces extrapulmonary disease may result in more frequent detection of these infections.
