Abstract

We have compared the BACTEC 460 system with the BACTEC MGIT 960 system for culture of mycobacteria from 1800 routine clinical specimens. Rate of isolation of M. tuberculosis and time to detection of positive culture was comparable for both systems (BACTEC 460, 35 isolates, BACTEC MGIT 960, 34 isolates). Contamination of cultures was more common with the BACTEC MGIT 960 system. With intensification of the decontamination process an acceptable contamination rate was achieved in the BACTEC MGIT 960 system but time to detection of positive culture was increased by 1 to 2 days.

摘要

我们将BACTEC 460系统与BACTEC MGIT 960系统用于1800份常规临床标本的分枝杆菌培养进行了比较。两种系统中结核分枝杆菌的分离率和培养阳性检测时间相当（BACTEC 460系统有35株分离菌，BACTEC MGIT 960系统有34株分离菌）。BACTEC MGIT 960系统的培养污染更为常见。通过强化去污过程，BACTEC MGIT 960系统达到了可接受的污染率，但培养阳性检测时间增加了1至2天。
