Serological diagnosis of Legionella species in 2,307 serum samples, collected in
Seoul, was conducted by an indirect fluorescent antibody assay(IFA). With an antibody
titer of ≥ 1:128 determined to be positive, 19(0.8%) of these samples were positive and
4(21.1%) positive serum samples were cross-reactive between Legionella species. The
number of samples with antibody titers ≥ 1:128 to Legionella pneumophila sg 1, L.
pneumophila sg 2, L. pneumophila sg 4, L. pneumophila sg 5, L. pneumophila sg 6,
Legionella longbeachae sg 1, Legionella feeleii sg 2, Legionella busanenesis, Legionella
anisa were 3(12.5%), 1(4.2%), 5(20.8%), 5(20.8%), 2(8.3%), 1(4.2%), 1(4.2%), 1(4.2%),
and 5(20.8%) respectively. Among 19 positive serum samples, 11(57.9%) were from
males and 8(41.2%) from females. Except for two samples(twenty), 17 positive samples
were from those older than 50 years of age.
