After thecomplete genome extraction of the strain was performed, the genomic DNA was partiallydigested by restriction enzyme Sau3AⅠ, the DNA fragments from 1 to 5Kb was clonedinto prokaryote expression vector pET-28a-c, and transformed host bacteria. The resultsshowed that we succeeded in constructing the gene expression library of haemophilusparasuis serovar 5, which is fundamental for the study of advanced gene screening. Inaddition, primer design was performed based on haemophilus influenzae in this study. In addition, PCR was performed by using genomic DNA of haemophilus parasuisserovar 5 as the template. The results demonstrated that we obtained two neo-gene:23SrRNA gene(conserved gene belonging to the large-subunit of ribosome) and adenylatecyclase gene(encodes adenylate cyclase and participates in converting adenyl nucleosidetriphosphate to cyclic adenosine3",5"-monophosphate). Furthermore, the phylogeneticanalyses between the species was performed, and neighbor-joining tree was constructedbased on comparison of 23S rRNA gene sequences, so it was illuminated betweenHaemophilus parasuis and other species in molecular evolution relationship.

选择我国流行优势菌株副猪嗜血杆菌血清5型地方株为研究对象，提取细菌基因组DNA，用限制性内切酶Sau3AⅠ对基因组DNA进行部分酶切，回收大小为1～5Kb的DNA片段，将其连接入原核表达载体pET-28a-c，最后转化宿主菌，结果成功地构建了基因表达文库，为后续的基因筛选工作奠定基础；另外，本研究选择嗜血杆菌属的流感嗜血杆菌为参考对象进行引物的设计，以副猪嗜血杆菌血清5型地方菌株的基因组DNA为模板，进行PCR扩增反应，结果表明成功地获得两个新基因：23S rRNA基因(存在于核糖体大亚基中的保守性基因)和腺苷酸环化酶基因(负责将腺嘌呤核苷三磷酸转变为环腺苷酸)，并进一步做了不同物种之间的分子系统发育分析，构建了基于23S rRNA基因的邻接法系统发育树，阐明了副猪嗜血杆菌与其它菌种的分子进化关系。
