摘要 目的研究河南省结核分枝杆菌基因型别与耐药性和地区分布关系。方法用间隔区寡核苷酸序列(Spoligotyping)基因分型技术对344株结核分枝杆菌进行分型。结果 344株结核分枝杆菌分为4个基因群[Beijing和Beijing近似群(简称北京群)、T群、Manu2群、S和LAM3群],共24个基因型,北京基因型有299株,占87.7%,但北京型与非北京型之间耐多药(MDR)株所占比例差异无统计学意义(χ2=1.46,P>0.05);北京基因型在≤60岁感染者中分离率占83.6%;除个别地区外,不同地区间的分布无显著性差异。结论河南省结核分枝杆菌以北京基因型为主要流行型,与MDR和任意耐药无相关性,以≤60岁感染者居多,嵩县分离率略低。
