A new commercial low-density microarray which identifies common extended-spectrum β-lactamase plasmid-mediated cephalosporinase genes, as well as carbapenemase (bla(KPC) and bla(NDM)) genes, was evaluated. We tested 207 clinical and reference/collection isolates of the Enterobacteriaceae possessing different bla genes. Overall, the sensitivity and specificity of the microarray were 100% for the detection of the plasmid-mediated bla(AmpC), bla(KPC), and bla(NDM) genes using bla gene sequencing as the reference method.
我们评估了一种新的商用低密度微阵列,该微阵列可识别常见的扩展谱β-内酰胺酶质粒介导的头孢菌素酶基因,以及碳青霉烯酶(bla(KPC)和 bla(NDM))基因。我们测试了 207 株具有不同 bla 基因的肠杆菌科临床和参考/收集分离株。总体而言,使用 bla 基因测序作为参考方法,该微阵列检测质粒介导的 bla(AmpC)、bla(KPC)和 bla(NDM)基因的灵敏度和特异性均为 100%。
