    Colonization of Legionella Species in Turkish Baths in Hotels in Alanya, Turkey
    (2015) Erdogan, Haluk; Arslan, Hande; 0000-0002-5708-7915; 0000-0002-9033-4236; 25850992; ABG-7034-2021; O-2247-2015
    This study evaluated the prevalence of Legionella species in water samples collected from Turkish baths in hotels in Alanya, Turkey, from August 2003 to September 2013. Water samples were collected in 100-mL sterile containers and then concentrated by filtration. Heat treatment was used to eliminate other microorganisms from the samples, which were then spread on Legionella-selective-buffered charcoal yeast extract alpha (BCYE-alpha) agar and on BCYE-alpha agar supplemented with glycine, vancomycin, polymyxin, and cycloheximide. Cysteine-dependent colonies were identified by latex agglutination. In total, 135 samples from 52 hotels with Turkish baths were evaluated. Legionella species were identified in 11/52 (21.2 %) hotels and 18/135 (13.3%) samples. The most frequently isolated species was Legionella pneumophila, with most isolates belonging to serogroups 6 (55.6 %) and 1 (22.2 %). The colony count was <100 colony-forming units (CFU) mL(-1) in nine samples, from 100 to 1000 CFU mL(-1) in six samples, and >1000 CFU mL(-1) in three samples. These findings suggest that the hot water systems of Turkish baths in hotels must be viewed as a possible source of travel-associated Legionnaires' disease, and preventative measures should be put in place.

    Domestically Acquired Legionnaires' Disease: Two Case Reports and a Review of the Pertinent Literature
    (2016) Erdogan, Haluk; Arslan, Hande; 27308081
    Background: Legionella species may colonize in home water systems and cause Legionnaires' disease (LD). We herein report two cases of sporadic LD associated with the solar energy-heated hot water systems of the patients' houses. Case Report: A 60-year-old woman with chronic bronchitis and diabetes mellitus presented with a high fever, abdominal pain, and diarrhea. Physical examination revealed rales, and her chest radiograph showed a homogeneous density in the left lung. The Legionella urinary antigen test was positive, and an indirect fluorescent antibody test revealed a serum antibody titer of 1/520 for L. pneumophila serogroup 1. In the second case, a 66-year-old man with diabetes mellitus was treated for pneumonia at another hospital. After the patient's general condition worsened and he required mechanical ventilation, he was referred to our hospital. The Legionella urinary antigen test was positive. Neither of the patients had been hospitalized or travelled within the previous month. Both patients used hot water storage tanks heated by solar energy; both also used an electrical device in the bathroom to heat the water when solar energy alone was insufficient. The hot water samples from the residences of both patients were positive for L. pneumophila serogroup 1. Conclusion: These cases show that domestic hot water systems heated by solar energy must be considered a possible source of community-acquired LD.
