Multicenter Evaluation of a New DNA Microarray for Rapid Detection of Clinically Relevant bla Genes from β-Lactam-Resistant Gram-Negative Bacteria

12 Jul 2011

Abstract excerpt

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...
