目的 探讨多态性相同的位点对北京家族结核分枝杆菌多位点可变数目串联重复序列(MIRU-VNTR)基因分型的影响,为合理选择分型位点提供科学依据.方法 分别选取9个及12个位点,构成4组MIRU-VNTR位点组合,其中,9位点组成的两个组合中,分别有两个不同位点(MIRU40/MIRU16)多态性一致,其余为相同位点;12位点的两个组合则分别包括另外两个多态性相同的位点(MIRU39/MIRU31).进行聚类分析,比较含有相同多态性的不同位点组合的分辨能力、成簇能力以及基因型特点.结果 9位点两个组合都将菌株分为三群,其中,Ⅲ群菌株仅有1株相同,分别占组合1、2的2.0%和1.6%.12位点组合也将菌株分为三群,第Ⅱ群菌株组成差异非常明显,完全没有相同的菌株.结论 多态性相同的位点对北京家族菌株MIRU-VNTR基因分型影响较大.在选择MIRU-VNTR分型位点时,应不仅仅检验位点的分辨能力和对成簇的影响,还应考虑有相同/相近多态性的位点对基因型构成的影响.
目的 探討多態性相同的位點對北京傢族結覈分枝桿菌多位點可變數目串聯重複序列(MIRU-VNTR)基因分型的影響,為閤理選擇分型位點提供科學依據.方法 分彆選取9箇及12箇位點,構成4組MIRU-VNTR位點組閤,其中,9位點組成的兩箇組閤中,分彆有兩箇不同位點(MIRU40/MIRU16)多態性一緻,其餘為相同位點;12位點的兩箇組閤則分彆包括另外兩箇多態性相同的位點(MIRU39/MIRU31).進行聚類分析,比較含有相同多態性的不同位點組閤的分辨能力、成簇能力以及基因型特點.結果 9位點兩箇組閤都將菌株分為三群,其中,Ⅲ群菌株僅有1株相同,分彆佔組閤1、2的2.0%和1.6%.12位點組閤也將菌株分為三群,第Ⅱ群菌株組成差異非常明顯,完全沒有相同的菌株.結論 多態性相同的位點對北京傢族菌株MIRU-VNTR基因分型影響較大.在選擇MIRU-VNTR分型位點時,應不僅僅檢驗位點的分辨能力和對成簇的影響,還應攷慮有相同/相近多態性的位點對基因型構成的影響.

Qbjective To investigate the effects on mycobacterial interspersed repetitive units-variablenumber tandem repeat(MIRU-VNTR) genotyping of loci with same allelic diversity in Mycobacterium tuberculosis Beijing genotype strains.Method R 2.9.1 software was used to construct phylogenetic tree based on two 9 and two 12 MIRU-VNTR loci combinations which have the same loci except MIRU40/MIRU16 and MIRU39/ MIRU31 respectively.The Hnnter-Gaston index,cluster rate and the characteristic of genotype were analyzed of two combinations.Results The phylogenetic tree based on the two 9 loci combination can be both divided into three groups.There is only one identical strain in group Ⅲ which accounts for 2.0% and 1.6% in the two 9 loci combinations,respectively.The phylogenetic tree based on the two 9 loci combination can be also devided into three groups.There is no identical strain in the three groups of the two 12 loci combinations.Conclusion Loci with the same allelic diversity have significant effects on MIRU-VNTR genotyping of Mycobacterium tuberculosis Beijing genotype strains.The effects on genotyping of loci that have the same or similar allelic diversity should also be considered besides the Hunter-Gaston index and cluster rate.
