摘要

目的:对奇异变形杆菌、洛菲氏不动杆菌16s rRNA 3’

3s rRNA 5’间序列（16S

3S rRNA intergenic spacer region

ISR）进行克隆测序

为分子探针技术鉴定两菌奠定基础。方法:针对临床常见致病菌16s rRNA 3’

3s rRNA 5’间序列两端的16S及23S rRNA保守序列设计PCR扩增的通用引物

对两菌进行扩增

利用PMD-18TVector质粒对两菌的PCR产物进行T载体克隆构建

测序后申报Genbank。结果:两菌的通用引物扩增产物构建的T载体克隆

测序结果经Blast分析

确定为两菌的ISR序列

申报Genbank获得接收。结论:成功的对奇异变形杆菌、洛菲氏不动杆菌ISR序列进行了克隆测序

该序列可以用于两种菌的通用引物PCR扩增技术鉴定。

Abstract

Objective:To clone and sequence of 16S~23S r RNA intergenic spacer region of Proteus mirabilis and Acinetobacter lowffii for further identification of these two bacteria by means of molecular probe.Methods: The PCR universal clinical common pathogenic bacteria primers for 16S and 23S rRNA’s conserved sequences were designed.Then the genomes of these two bacteria were amplified

T Vector clones were constructed with PMD-18 T Vector ad PCR products.The vectors were sequenced and the sequence was submitted to Genbank.Results: T Vector clones were constructed with products amplified by using universal primers;according to Blast analyses

the results of sequencing were determined as ISR sequences of the two kinds of bacteria.And the reports to Genbank were accepted.Conclusion: Genbank accepted the cloning and sequencing results of Proteus mirabilis and Acinetobacter lwoffii as new sequences.And these sequences can be used to identify the two bacteria by universal primers.
