title: DISTRIBUTION OF LEGIONELLA PNEUMOPHILA SEROGROUPS ISOLATED FROM WATER SYSTEMS OF PUBLIC FACILITIES IN BUSAN, SOUTH KOREA.
abstract: Legionella pneumophila is the major causes of legionellosis worldwide. The distribution of L. pneumophila was investigated in water systems of public facilities in Busan, South Korea during 2007 and 2013-2014. L. pneumophila was isolated from 8.3% of 3,055 samples, of which the highest isolation rate (49%) was from ships and the lowest 4% from fountains. Serogroups of L. pneumophila isolated in 2007 were distributed among serogroups (sgs) 1-7 with the exception of sg 4, while those of isolates during 2013 and 2014 included also 11 sgs ( 1, 2, 3, 4, 5, 6, 7, 8, 12, 13, 15). L. pneumophila sg 1 was predominated among isolates from fountains (75%), hotels (60%), buildings (44%), hospitals (38%), and public baths (37%), whereas sg 3 and sg 7 was the most prevalent from ships (46%) and factories (40%), respectively. The predominated serogroup of L. pneumophila isolates from hot and cooling tower water was sg 1 (35% and 46%, respectively), while from cold water was sg 3 (29%). These results should be useful for epidemiological surveys to identify sources of outbreaks of legionellosis in Busan, South Korea.
