摘    要:传染性萎缩性鼻炎是养猪业中的一种重要的呼吸道传染病,产毒素多杀性巴氏杆菌是其重要的病原之一,外膜蛋白H(OmpH)在该菌的致病和免疫中发挥重要作用。本研究克隆了产毒素多杀性巴氏杆菌HN-13株的ompH基因,进行了序列分析,并在大肠杆菌中高效表达,用表达产物建立了间接ELISA方法。同时用生物信息学方法对ompH基因及其编码蛋白的结构特性进行了分析和预测,表明OmpH是一种通道蛋白。

关 键 词:多杀性巴氏杆菌  外膜蛋白H  克隆  表达  结构预测  ELISA

Abstract:Progressive atrophic rhinitis is an important respiratory disease in swine industry, caused by toxigenic Pasteurella multocida. The OmpH of Pasteurella mumtocida is a major outer membrane protein involved in the pathogenesis and immunity. In this study the ompH gene of P. multocida strain HN-13 of swine origin was cloned, sequenced and highly expressed in E. coli, and an indirect enzyme-linked immunosorbent assay (ELISA) was established using the recombinant protein. The structure of the ompH gene and its protein was analyzed using bioinformatics methods, suggesting that the OmpH is a porin.
Keywords:Pasteurella multocida  outer membrane protein H  cloning  expression  structural prediction
