Laboratory and Clinical Evaluation of DNA Microarray for the Detection of Carbapenemase Genes in Gram-Negative Bacteria from Hospitalized Patients

(a) Sensitivity of the microarray assays. The indicated carbapenemase reference plasmids were subject to series dilutions and hybridized to the DNA microarrays. The plasmids copy numbers are diluted from 3×10¹ to 3×10⁵ copies/μL. (b) KPC reference plasmids (3×10¹ to 3×10⁵ copies/μL) were detected by real-time PCR, (c) NDM-1 reference plasmids (3×10¹ to 3×10⁵ copies/μL) were detected by real-time PCR.
