中文摘要: |
目的:探讨结核分枝杆菌eis 基因突变与氨基糖苷耐药之间的相互关系。方法:以本室保存的35 株已确定耐一线药物(异烟
肼、利福平、乙胺丁醇、链霉素)的结核分支杆菌为研究对象,应用BECTEC960 测定其二线药物(阿米卡星、卡那霉素)的耐药情
况,同时应用基因测序的方法测定结核分枝杆菌eis 基因突变情况,分析eis 基因突变与氨基糖苷耐药之间的相互关系。结果:氨
基糖苷耐药的部分结核分杆杆菌中,eis 基因487 位碱基出现突变,相应的163 位氨基酸密码子由CGT 突变为CAT,即由缬氨酸
变为异亮氨酸。结论:eis 基因V163I 突变(缬氨酸变为异亮氨酸)可能与结核分枝杆菌耐氨基糖苷类药物有关。 |

Objective: To investigate the relationship between enhanced invracellular survival (eis) gene mutations and aminoglycoside-
resistance in MTB. Methods: 35 strains of MTB resistant to isoniazid, rifampicin, ethambutol and streptomycin were chosen, the
resistance to amikacin and kanamycinwere determined byBECTEC960, eis genemutationswere identified by PCR and sequencing. Results:
There was Eis gene mutation of G487A in 4 strains and the amino acid changed from valine to isoleucine. Conclusion: The eis V163I
mutation might associate with aminoglycoside-resistance in MTB. |
