Criteria for Evaluation of the Immunoblot in the Diagnosis of LymeBorreliosis Using Borrelia afzelii, Borrelia garinii and Borrelia burgdorferi sensustricto

Overview

The immunoblot was prepared from genotypes Borrelia afzelii (KC 90), Borrelia garinii (M 192) andBorrelia burgdorferi sensu stricto (B 31). Sera of 63 patients with different forms of Lyme borreliosiswere examined and 40 healthy donors in the endemic area of the disease. In class IgM in the groupof patients significantly more frequently antibodies against OspC, p39, p41 B. afzelii, p39, p41, p66,p83 B. garinii and OspC1, OspA, B. burgdorferi sensu stricto were found. In class IgG there wereantibodies against p39, p41, p93 B. afzelii, p14, p41, p93 B. garinii and OspA, OspC p93 B. burgdorferisensu lato. Based on the assembled results by means of discrimination analysis and logisticregression the most suitable combinations of antigens for evaluation of immunoblots in differentgenotypes were determined. Furthermore evaluation was suggested using a combination of antigens of several genotypes which led to an increased sensitivity and specificity of the immunoblot.Tables were prepared for easier evaluation of newly examined sera samples.

Key words:
immunoblot – Lyme borreliosis – Borrelia burgdorferi sensu lato.
