[Antibodies against Borrelia garinii in diagnosis of Lyme disease].

Prevalence of antibodies against Borrelia garinii (Bg) was analysed in sera of 42 patients with Lyme borreliosis confirmed through demonstration of antibodies against antigen 41 kDa of Borrelia burgdorferi sensu stricto (Bbss). IgM or IgG antibodies against Bg were found in sera of 88% patients. Agreement of the results between Bg and Bbss tests related to IgM antibodies reached 84% and to IgG antibodies 76%. Comparison of individual results revealed significant positive correlation of optical densities in respect to both IgM and IgG antibodies. These results indicate possible use of detection of anti-Borrelia garinii antibodies in diagnostics of Lyme borreliosis in Poland.
