Simple and Reliable Multiplex PCR Assay for Surveillance Isolates of Vancomycin-Resistant Enterococci

Conditions have been optimized for the use of a multiplex PCR for the detection of vancomycin-resistant enterococci in nosocomial surveillance specimens. Seven primer sets targeting the genes vanA, vanB, vanC1, vanC2/C3 Enterococcus faecalis-specific, Enterococcus faecium-specific, and rrs (16S rRNA) were used in one reaction tube. The PCR method developed in the present study is simple and reliable for the rapid characterization of vancomycin-resistant enterococci.
