The use of the (GTG)5 oligonucleotide, a repetitive marker in the Mycobacterium tuberculosis chromosome, as a primer in association with an IS6110 outlooking primer has been successfully applied to a PCR-based fingerprinting method. This method classified 62 strains of M. tuberculosis, isolated from human immunodeficiency virus-seropositive and -seronegative patients in different regions of Italy and Pakistan, as having 53 different patterns. The results were compared with traditional IS6110 fingerprinting, by which 47 distinct patterns were observed.
(GTG)5寡核苷酸是结核分枝杆菌染色体中的一种重复标记,将其用作引物并与IS6110外显引物联合使用,已成功应用于基于聚合酶链反应(PCR)的指纹识别方法。该方法对从意大利和巴基斯坦不同地区的人类免疫缺陷病毒血清阳性和血清阴性患者中分离出的62株结核分枝杆菌进行分类,结果显示有53种不同的模式。将这些结果与传统的IS6110指纹识别结果进行比较,后者观察到47种不同的模式。
