Abstract

The Xpert Carba-R kit, version 2 (v2), which has been improved for the efficient detection of blaOXA-181 and blaOXA-232 genes, was tested on a collection of 150 well-characterized enterobacterial isolates that had a reduced susceptibility to carbapenems. The performance of the Xpert Carba-R v2 was high, as it was able to detect the five major carbapenemases (NDM, VIM, IMP, KPC, and OXA-48). Thus, it is now well adapted to the carbapenemase-producing Enterobacteriaceae epidemiology of many countries worldwide.

摘要

已改进用于高效检测blaOXA - 181和blaOXA - 232基因的Xpert Carba - R试剂盒版本2(v2),在150株对碳青霉烯类药物敏感性降低的、特征明确的肠杆菌科分离株样本上进行了测试。Xpert Carba - R v2的性能很高,因为它能够检测出五种主要的碳青霉烯酶(NDM、VIM、IMP、KPC和OXA - 48)。因此,它现在非常适合全球许多国家产碳青霉烯酶肠杆菌科细菌的流行病学情况。
