摘要
The fla gene of Borrelia burgdorferi GeHo was analyzed and expressed in Escherichia coli. The structural gene encodes a flagellar protein of 336 amino acids. Comparative sequence analysis of the amino acid sequence revealed a high degree of sequence conservation with flagellins from both phylogenetically related and unrelated bacteria. The antigenic properties of the B. burgdorferi Fla protein were studied by synthesizing overlapping octapeptides, which were screened by using a battery of different monoclonal and polyclonal antibodies from various species directed against native and denatured flagellar proteins. No single species-independent immunodominant epitope could be located. However, immunoreactive oligopeptides clustered within the variable middle region (N-180 to I-260). This region could constitute a candidate antigen for more specific and sensitive serodiagnosis of Lyme borreliosis.
