摘要 背景:利用现代分子生物学来帮助我们理解结核分枝杆菌的传播和流行病学机理。目的:分析耐药结核分枝杆菌分子流行病学和1995—2004年芬兰耐异烟肼及利福平相关突变菌株。设计:对3959株新结核分枝杆菌菌株进行了药物敏感性试验,如有必要,所有的耐药性表型菌株都进行了IS6110限制性片段长度多态性和间隔寡核苷酸分型分析。对耐异烟肼及利福平菌株分别进行了katG 315位密码子和rpoB耐性基因测序。结果:在测试的3959(92.4%为培养阳性)株分离株中,183个(4.6%)对至少一种一线抗结核药耐药;14(0.4%)株为耐多药。37株(20.4%)耐性菌株属于17个簇,其中最大的簇包括4个分离株。北京家族占所有耐药菌株的8.8% (16株)。在异烟肼耐药菌株中,katG的Ser315Thr突变占46.7%(56株);在利福平耐药菌株中rpoB突变占85.7%(18株)。结论:耐药结核病在芬兰传染率很少,尤其在本地和外来人口间。如果存在产生耐多药的危险因素,筛查异烟肼和利福平耐药相关突变是可行的。
