The use of the COBAS AMPLICOR System (Roche Molecular Diagnostics, Basel, Switzerland), the only automated system for PCR testing, was evaluated for a rapid identification of mycobacteria with positive BACTEC 12B cultures. Two hundred ninety-six specimens with a growth index of >/=30 were analyzed for the presence of Mycobacterium tuberculosis complex, Mycobacterium avium, and Mycobacterium intracellulare. Compared to traditional methods and provided that samples with PCR inhibition are retested at a 1:10 dilution, the sensitivity and specificity of the COBAS AMPLICOR System with BACTEC 12B cultures were 100 and 98%, respectively. The COBAS AMPLICOR method is rapid and reliable for identifying the most common mycobacteria in cultures.
对唯一的PCR检测自动化系统COBAS AMPLICOR系统(罗氏分子诊断公司,瑞士巴塞尔)进行了评估,以快速鉴定BACTEC 12B培养阳性的分枝杆菌。对296份生长指数≥30的标本进行分析,检测是否存在结核分枝杆菌复合群、鸟分枝杆菌和胞内分枝杆菌。与传统方法相比,且前提是对有PCR抑制作用样本以1:10稀释度重新检测,COBAS AMPLICOR系统对BACTEC 12B培养物检测的灵敏度和特异性分别为100%和98%。COBAS AMPLICOR方法在鉴定培养物中最常见分枝杆菌方面快速且可靠。
