title: [The presence of antibodies to Borrelia burgdorferi associated with immunologic complexes in sera of foresters].
abstract: Binding of antibodies specific to Borrelia burgdorferi in circulating immune complexes can lead to false negative results in serological tests. The aim of our study was to determine the presence of IgM antibodies to Borrelia burgdorferi bound in immune complexes in 52 sera of foresters the National Park in Karkonosze. Free and bound in immune complexes IgM antibodies present in 6 (11.5%) examined sera. In 24 (46.2%) seronegative sera after dissociation of immune complexes IgM antibodies to spirochaeta were found. The rest of the examined seronegative sera we failed to find IgM antibodies to Borrelia burgdorferi. The diagnostic assay, such as antibody analysis of immune components is useful in establishing of the diagnosis of borreliosis in seronegative cases and monitoring of disease activity. That method should be introduced for routine diagnosis of Lyme disease.
