The molecular and antigenic variabilities of BmpA (P39) among European isolates of Borrelia burgdorferi were analyzed. The bmpA sequences of 12 isolates representing all three species of B. burgdorferi sensu lato pathogenic for humans were amplified by PCR, cloned, and sequenced. The BmpA protein of Borrelia garinii is heterogeneous, with an amino acid(More)
To improve IgG antibody detection in the serodiagnosis of Borrelia burgdorferi infection, indirect enzyme-linked immunosorbent assays (ELISAs) were developed utilizing purified recombinant antigens of B. burgdorferi sensu lato: the chromosomally encoded proteins p100 of strain PKo (B. afzelii) and p4li (internal flagellin fragments) derived from strains(More)
Infection with Borrelia garinii outer surface protein (Osp) A serotype 4 strains has been correlated with the development of neuroborreliosis in Lyme borreliosis patients in Europe. OspA serotype 4 isolates have been recovered primarily from human cerebrospinal fluid, suggesting a tropism for this environment. Previous studies with monoclonal antibodies(More)
Molecular analyses of the genes encoding OspC, a major immunodominant protein of Borrelia burgdorferi sensu lato, revealed a considerable degree of heterogeneity. In the present study, we investigated whether a similar heterogeneity of the OspC phenotype can be shown by analysis with monoclonal antibodies (MAbs). Thirteen OspC-specific MAbs (L22 MAbs) were(More)
Neuroborreliosis is the most frequent manifestation of the second stage of Lyme borreliosis in Europe. However, only few isolates from the cerebrospinal fluid (CSF) have been characterized with controversial results. A large panel of 36 CSF isolates isolated over a 10-year period in Munich has now been analyzed for their OspA and OspC type, resulting in at(More)
Borrelia burgdorferi sensu lato, the etiological agent of Lyme borreliosis, has been divided into three genospecies: B. burgdorferi sensu stricto (OspA-type 1), B. afzelii (OspA-type 2) and B. garinii (OspA-type 3-7). Whereas in Europe B. afzelii (OspA-type 2) is predominant among human skin isolates and B. garinii (OspA-type 3-7) among human CSF isolates,(More)
We have previously described the use of the following recombinant antigens for serodiagnostic immunoblots: p83/100, p39, OspC and p41 (flagellin) internal fragment [Wilske et al. (1993) Med Microbiol Immunol 182:255-270; Rossler et al. (1997) J Clin Microbiol 35:2752-2758]. In our currently used immunoblot p83/100 is derived from strain PKo (Borrelia(More)
25 skin biopsy isolates of Borrelia burgdorferi sensu lato, mainly from German patients with erythema migrans [EM], borrelial lymphocytoma [BL] and acrodermatitis chronica atrophicans [ACA], were species-differentiated using pulsed-field gel electrophoresis (PFGE). The isolates revealed 15 B. afzelii, 8 B. garinii and 2 B. burgdorferi sensu stricto species(More)
Immunodominant proteins are variable in molecular and antigenic structure among different genospecies of Borrelia burgdorferi sensu lato. We have recently developed an immunoblot using five recombinant antigens: the chromosomal-encoded B. burgdorferi proteins p100, the flagellin and an internal flagellin fragment thereof, and the plasmid-encoded(More)
It has been shown by analysis with monoclonal and polyclonal antibodies that outer surface protein C (OspC) of Borrelia burgdorferi sensu lato is highly heterogeneous. To determine if the heterogeneity has a genetic basis, the genes of 18 different B. burgdorferi sensu lato strains have been amplified by PCR, cloned, and sequenced. The ospC genes could be(More)
