title: Rapid detection and sequence-specific differentiation of extended-spectrum beta-lactamase GES-2 from Pseudomonas aeruginosa by use of a real-time PCR assay.
abstract: The LightCycler was compared to nested PCR for the detection of bla(GES/IBC) genes from 100 Pseudomonas aeruginosa clinical isolates. The real-time PCR assay detected a bla(GES/IBC) gene product from 83 isolates, exhibiting a sensitivity and specificity of 94.3 and 100% respectively, compared to nested PCR and DNA sequencing.
