| 摘 要： | 为了探讨鸭疫里默氏杆菌(Riemerella anatipestifer, RA)云南流行株的外膜蛋白A (OmpA)的基因序列差异及其与16S rRNA序列的相关性,PCR扩增18株云南流行株鸭疫里默氏杆菌OmpA基因及16S rRNA核苷酸序列,分别构建其系统进化树,分析其系统进化关系。结果表明,18株鸭疫里默氏杆菌OmpA基因分为2个群,其同源性分别为86%~99.2%和92.6%~100%。18株鸭疫里默氏杆菌16S rRNA基因同属1个群,同源性高达96.1%~100%。 RA-1、RA-2、RA-11和RA-39 4株分离株的OmpA基因位于进化树的同一个亚群,其16S rRNA基因也位于进化树的同一亚群,两者呈现出明显的相关关系,其他14株分离株的OmpA基因系统进化树与16S rRNA基因系统进化树无明显的相关关系。

| Abstract: | To analysis the OmpA and 16S rRNA gene of Riemerella anatipestifer isolated strains in Yunnan province and explore the correlationship between OmpA and 16S rRNA gene on phylogenetic trees, OmpA and 16S rRNA gene was amplified respectively by PCR to construct the phylogenetic trees. Results analysis showed that the OmpA gene of 18 Yunnan isolated RA strains were situated in two groups and their homology were 86% to 99.2% and 92.6% to 100% respectively, the 16S rRNA gene of 18 Yunnan isolated RA strains were situated in one group and their homology was 96.1% to 100%.It’s worth noting that the RA-1,RA-2,RA-1 and RA-39 isolated strains belonged to the same subgroup on both the OmpA phylogenetic tree and 16S rRNA phylogenetic tree with the higher homology 97.3% to 99.2% and 99.6% to 100% respectively, the two phylogenetic trees showed a significant correlation within RA-1,RA-2,RA-1 and RA-39 isolated strains and showed no correlation within the other 14 isolated strains. |
