Rapid PCR amplification protocols decrease the turn-around time for detection of antibiotic resistance genes in Gram-negative pathogens

摘要

A previously designed end-point multiplex PCR assay and singleplex assays used to detect β-lactamase genes were evaluated using rapid PCR amplification methodology. Amplification times were 16-18 minutes with an overall detection time of 1.5 hours. Rapid PCR amplifications could decrease the time required to identify resistance mechanisms in Gram-negative organisms.
