The objective of this study was to investigate the frequency of contamination of Legionella in the
King Fahd Hospital of the University (KFHU) cooling tower water of air conditioning system and other water
supplies. A total of 300 samples were collected from various sites in KFHU. Water samples were collected from
the cooling tower (88), hot-shower head (40), cold-shower head (59), engineering building (12) and drinking
fountain (12). Swab samples were also collected from shower heads (44) and air ventilator (45). Overall
Legionella was detected in only 5 (5.68%) out of 88 water samples and yielded 7 isolates. All other water
samples that were collected from other sites were negative for the presence of Legionella. Culturing the hospital
water supply for Legionella was the first step in the assessment of the risk for hospital-acquired Legionnaires’
(LD). Legionella is a common cause of hospital-acquired pneumonia, especially for immunocompromised
patients.
