Levels of antibody against Legionella pneumophila serotype 1 in healthy populations in five areas in New Zealand.
Levels of antibody to Legionella pneumophila serogroup 1 in five areas of New Zealand were determined by indirect immunofluorescence. Both immunoglobulin G (IgG) and IgM levels were separately assessed. Of the 500 people studied, 2.8% had IgG titers of greater than or equal to 1:128 and 4.0% had IgM titers of greater than or equal to 1:128. Higher levels of IgG reactivity were noted in the southern part of New Zealand, but neither age nor sex appeared to be related to variations in antibody levels.
