| 摘 要： | 通过PCR反应扩增7株鸡奇异变形杆菌和1株兔奇异变形杆菌的23SrRNA基因片段(1045bp),经克隆测序,用DNA Star分析软件将所获得的序列与GenBank中收录的奇异变形杆菌、普通变形杆菌以及其他相近属的23S rRNA基因序列进行同源性比较,并由此构建奇异变形杆菌系统进化发生树。结果表示,本实验室保存的7株鸡奇异变形杆菌核苷酸序列与GenBank中收录的奇异变形杆菌核苷酸序列同源性为99.4%～99.8%,与兔奇异变形杆菌核苷酸序列同源性为98.8%～99.3%,与普通变形杆菌的核苷酸序列同源性为95.4%～96.2%,而与其他相近属同源性只有92.9%～93.4%。结果表明,23S rRNA基因序列分析可以作为鉴定奇异变形杆菌的一种快速、简便的方法。

| Abstract: | To assess the evolution of Proteus mirabilis by 23S rRNA genes,To establish the sequence analysis of 23S rRNA of Proteus mirabilis was analyzed.The fragments(1 045 bp) of 23S rRNA genes of seven chicken Proteus mirabilis strains and one rabbit Proteus mirabilis strain were amplified by PCR and were sequenced.The sequences obtained in this paper were compared with the Proteus mirabilis 23S rRNA sequence reported in GenBank and other similar generas by the software of DNAStar analyses.The phylogenetic tree of... |
