Abstract

We evaluated a new mycobacterial culture system, MB Redox, for recovery rate and time to detection of mycobacteria from 742 consecutive respiratory specimens and compared the results to those found with Löwenstein-Jensen (LJ) medium. Twenty specimens (2.7%) were positive for M. tuberculosis: 17 on LJ medium and 19 in MB Redox, with 16 specimens positive in both media. In addition, 24 specimens (3.2%) were positive for nontuberculous mycobacteria (NTM), 20 on LJ medium, 18 in MB Redox, and 14 in both media. For M. tuberculosis, the mean times to detection were 28.9 days on LJ medium and 23.6 days in MB Redox, and for NTM, the mean times to detection were 40.6 days on LJ medium and 32.3 days in MB Redox.

摘要

我们评估了一种新的分枝杆菌培养系统MB Redox,用于从742份连续呼吸道标本中回收分枝杆菌的回收率和检测时间,并将结果与 ​​Löwenstein-Jensen(LJ)培养基的结果进行比较。20份标本(2.7%)结核分枝杆菌呈阳性:17份在LJ培养基上呈阳性,19份在MB Redox中呈阳性,16份在两种培养基中均呈阳性。此外,24份标本(3.2%)非结核分枝杆菌(NTM)呈阳性,20份在LJ培养基上呈阳性,18份在MB Redox中呈阳性,14份在两种培养基中均呈阳性。对于结核分枝杆菌,在LJ培养基上的平均检测时间为28.9天,在MB Redox中为23.6天;对于NTM,在LJ培养基上的平均检测时间为40.6天,在MB Redox中为32.3天。
