摘要 目的:描述波兰耐药结核分枝杆菌分离株的特征,估计人群中近期传播的数量。设计:应用间隔区寡核苷酸分型及 IS6110DNA 指纹图谱法对2000年波兰251名耐药肺结核患者分离株进行分析。对部分菌株进行 rpoB、katG 和/或 inhA基因调节区测序分析。结果:应用间隔区寡核苷酸分型/IS6110-RFLP 相结合的成簇定义,29%的菌株成簇,提示存在近期传播。成簇菌株中某些病例的传播联系得到了流行病学资料证实,多数分离株的突变与利福平和异烟肼耐药相关。年龄、性别、移民身份、用药史和成簇没有关系,耐多药病例更容易成簇。在波兰,也发现了北京基因型分离株,但频率较邻国偏低。结论:证实了耐药结核菌的传播及其对波兰发生耐药结核病的作用。
