Abstract

We compared carbapenemase detection among 266 Gram-negative bacilli (161 carbapenemase producers) using the Carba NP tests issued by the CLSI (CNPt-CLSI) and a novel protocol (CNPt-direct) designed for carbapenemase detection direct from bacterial cultures (instead of bacterial extracts required by the CLSI tests). The specificities were comparable (100%), but the CNPt-direct was more sensitive (98% versus 84%). The CNPt-direct was easier to perform due to the direct use of colonies and offered a more robust detection of carbapenemase producers.

摘要

我们使用美国临床和实验室标准协会（CLSI）发布的碳青霉烯酶检测方法（CNPt-CLSI）和一种专为直接从细菌培养物中检测碳青霉烯酶而设计的新方法（CNPt-direct，而非CLSI检测方法所要求的细菌提取物），对266株革兰氏阴性杆菌（161株碳青霉烯酶产生菌）进行了碳青霉烯酶检测比较。两种方法的特异性相当（均为100%），但CNPt-direct更敏感（98%对84%）。由于直接使用菌落，CNPt-direct操作更简便，且对碳青霉烯酶产生菌的检测更可靠。
