Isolation of Borrelia burgdorferi from the CSF is relatively rare. The present report describes the first three isolations in Switzerland. Clinically, our first observation confirmed the frequent association of B. burgdorferi with peripheral facial paresis in children. The other two cases illustrate the variety of symptoms in neuro-borreliosis. In the first case the culture was positive after 6 weeks. The results of serologic tests (indirect immunofluorescence and ELISA) for detection of antibodies against B. burgdorferi were negative or non-significant in this child's serum. On the other hand, specific antibodies (IgG) were detected in the serum by western blot. Culture of the second CSF already showed Borrelia growth after 10 days. Immunofluorescence revealed high antibody titers (1/256) against B. burgdorferi in this patient's serum. IgG showed a weakly positive reaction in western blot. The reliability of this result was confirmed by isolation of Borrelia. In neither of the two CSF could intrathecal synthesis of specific antibodies be demonstrated. In the third case, however, immunofluorescence showed IgG antibody titers of 1/128 in the CSF and 1/512 in serum. Intrathecal synthesis of specific antibodies was demonstrated with an index of 13.4 (norm < 2). Western blot confirmed the specificity of the reactions observed with the serum and CSF IgG. Culture of CSF produced significant growth of Borrelia within 7 days. Protein profile and reactions with poly- and monoclonal antibodies confirmed that the three strains belonged to B. burgdorferi.(ABSTRACT TRUNCATED AT 250 WORDS).
