Abstract
目的对荧光PCR熔解曲线法检测结核分枝杆菌耐利福平突变方法进行临床研究,评价检测能力及在国境口岸的应用价值。方法应用荧光PCR熔解曲线法检测结核病人临床分离结核分枝杆菌,以传统药物敏感性试验为标准,获得该方法的灵敏性、特异性。结果对347例结核病人临床分离培养样本,传统药物敏感性试验检出271例利福平敏感标本,76例利福平耐药标本。荧光PCR熔解曲线法检出269例利福平敏感标本,78例利福平耐药标本,灵敏性为93.42%,特异性为97.42%,符合率为96.54%。结论荧光PCR熔解曲线法检测速度快速、灵敏度高、特异性强,可用于结核分枝杆菌利福平耐药突变的快速检测,适于国境口岸对耐多药结核病的快速筛查
