The detection of spirochetes in 15 patients with clinically documented early disseminated LB has been analysed when using cultivation method of the plasma or the cerebrospinal fluid, electron microscopy, commercial Western blot and detecting the DNA of the pathogen in vitro cultures by PCR-RFLP. Spirochetes were isolated in eight blood and one cerebrospinal fluid culture samples. In seven cases (47%), previous serodiagnostic laboratory tests were negative. Borrelial DNA was detected by PCR in 67% patients (9 blood samples and 1 CSF sample). Using MseI restriction fragments of PCR products of the amplified rrf-rrl region, we identified Borrelia garinii (80%), one B. afzelii isolate and one B. burgdorferi s.s.
