The Carba NP test was evaluated against a panel of 61 carbapenemase-producing bacterial species (15 producing class A carbapenemases, 15 producing class D carbapenemases, and 31 producing metallo-β-lactamases) and against 111 isolates with non-wild-type carbapenem susceptibility but not producing carbapenemase. Carbapenemase production was verified by PCR and UV-spectrophotometric measurement of imipenem hydrolysis. No false positives were seen, but there were consistent problems with the detection of OXA-48-like enzymes and also some rarer class A enzymes.
针对一组61种产碳青霉烯酶的细菌(15种产A类碳青霉烯酶、15种产D类碳青霉烯酶和31种产金属β-内酰胺酶)以及111株碳青霉烯药敏非野生型但不产碳青霉烯酶的菌株,对Carba NP试验进行了评估。通过PCR和亚胺培南水解的紫外分光光度法测定来验证碳青霉烯酶的产生。未发现假阳性,但在检测OXA-48样酶以及一些罕见的A类酶时存在持续问题。
