We evaluated the performance of the RESIST-4 O.K.N.V. assay (Coris) with 98 isolates to detect OXA-48-like and KPC-, NDM-, and VIM-type carbapenemases directly on positive human blood cultures. OXA-48-like and KPC-type isolates were correctly detected, but the detection of NDM- and VIM-type carbapenemases was weak and variable. We show that repeating the test on a 4-h subculture improves the detection of NDM- and VIM-type carbapenemases to 100%.
我们用 98 株分离株评估了 RESIST-4 O.K.N.V. 检测(Coris)在阳性血培养物上直接检测 OXA-48 样、KPC-、NDM-和 VIM 型碳青霉烯酶的性能。OXA-48 样和 KPC 型分离株被正确检测到,但 NDM-和 VIM 型碳青霉烯酶的检测较弱且不稳定。我们表明,在 4 小时的亚培养物上重复测试可将 NDM-和 VIM 型碳青霉烯酶的检测提高到 100%。
