Abstract:
Serological investigation of antibodies to Legionella species in 1,802 sera collected in seoul was conducted with indirect fluorescent antibody assay (IFA). With an antibody titer of > or =1:128 to be positive, 17 (0.9%) of these sera were positive and 6 (35.3%) of positive sera showed cross-reactions between Legionella species. The number of sera with antibody titers of > or =1:128 to L. pneumophila serogroup 1, L. pneumophila serogroup 4, L. pneumophila serogroup 5, L. bozemanii, L. micdadei, L. anisa were 6 (35.3%), 3 (17.6%), 3 (17.6%), 2 (11.8%), 1 (5.9%), 2 (11.8%) respectively. Among 17 positive sera, 10 (58.8%) sera were from male and 7 (41.2%) from female. An average age of them was 68.9 (+/-15.3; 27~89). Except for one serum, 16 (94.1%) of positive sera were from those older than 50 years old. The result suggests that the aged over 50 years old should be more careful of Legionella infection.
