Case Report: First Report of Fatal Legionella pneumophila and Klebsiella pneumoniae Coinfection in a Kidney Transplant Recipient

A very rare case of pulmonary Klebsiella pneumoniae-Legionella pneumophila coinfection in a double kidney transplanted man affected by the chronic renal disease is described. Cases of Legionnaires' disease with an incubation period of 14 days have rarely been documented. Despite the long period of hospitalization, typing of clinical and environmental L. pneumophila strains demonstrated that the patient's home water distribution system was the source of infection, highlighting that Legionella house contamination can be a hidden risk, especially for immune-compromised people.

This article describes a rare case of pulmonary Klebsiella pneumoniae-Legionella pneumophila coinfection in a man with chronic renal disease who had undergone a double kidney transplantation. Cases of Legionnaires' disease with a 14-day incubation period are seldom documented. Despite a lengthy hospitalization, typing of clinical and environmental L. pneumophila strains revealed that the patient's home water distribution system was the source of infection, emphasizing the concealed risk of Legionella contamination in households, particularly for immunocompromised individuals.
