    • An expression vector for expressing a protein or polypeptide in a bacterium, which comprises a first DNA sequence encoding at least a secretion signal of a lipoprotein, and a second DNA sequence encoding a protein or fragment thereof, or polypeptide or peptide heterologous to the bacterium which expresses the protein or fragment thereof, or polypeptide or peptide. The bacterium expresses a fusion protein of a lipoprotein or lipoprotein segment and the protein or fragment thereof, or polypeptide or peptide heterologous to the bacterium which expresses the protein or fragment thereof, or polypeptide or peptide. Such expression vectors increase the immunogenicity of the protein or fragment thereof, or polypeptide or peptide by enabling the protein or fragment thereof, or polypeptide or peptide to be expressed on the surface of the bacterium. Bacteria which may be transformed with the expression vector include mycobacteria such as BCG. The expression vectors of the present invention may be employed in the formation of live bacterial vaccines against Lyme disease wherein the bacteria express a surface protein of Borrelia burgdorferi, the causative agent of Lyme disease.
    • 用于在细菌中表达蛋白质或多肽的表达载体,其包含编码脂蛋白的至少一种分泌信号的第一DNA序列和编码其蛋白质或其片段的第二DNA序列,或与该细菌异源的多肽或肽 表达蛋白质或其片段,或多肽或肽。 细菌表达脂蛋白或脂蛋白片段的融合蛋白,以及与表达其蛋白质或片段,或多肽或肽的细菌异源的蛋白质或其片段或多肽或肽。 这种表达载体通过使蛋白质或其片段或多肽或肽在细菌表面上表达而增加蛋白质或其片段或多肽或肽的免疫原性。 可用表达载体转化的细菌包括分枝杆菌如BCG。 本发明的表达载体可以用于形成针对莱姆病的活细菌疫苗,其中细菌表达布氏疏螺旋体的表面蛋白,其是莱姆病的致病因子。
