伯氏疏螺旋体会导致莱姆病,这是一种可在人类身上持续多年的多系统疾病。我们描述了同源基因之间的重组编码的主要外表面蛋白(Osps)A和B的B。Burgdorferi,其既缺失OSP基因序列又产生嵌合基因融合体。重组osp基因存在于多种菌株中,并编码缺乏某些特征性Osp表位的独特蛋白质。Osp中通过重组产生的抗原变异可能与B的持续存在有关。在感染的宿主中,OspA和OspB的表达与伯氏螺旋体的表达相关,并且对于OspA和OspB作为莱姆病的诊断或疫苗候选物的实用性具有重要意义。我们还描述了Osp的变化所产生的无义突变和序列的分歧,这也可能是Osp多态性的重要来源。
Borrelia burgdorferi causes Lyme disease, a multisystem illness that can persist in humans for many years. We describe recombination between homologous genes encoding the major outer surface proteins (Osps) A and B of B. burgdorferi which both deletes osp gene sequences and creates chimaeric gene fusions. Recombinant osp genes occur in multiple strains and encode unique proteins that lack some characteristic Osp epitopes. Antigenic variation in Osp through recombination may be relevant to the persistence of B. burgdorferi in an infected host, and has important implications for the utility of OspA and OspB as diagnostic or vaccine candidates for Lyme disease. We also describe Osp variation arising from nonsense mutations and sequence divergence, which may also represent significant sources of Osp polymorphism.
