Abstract

Linezolid-resistant enterococcus spp. are increasingly recognized by diagnostic laboratories. Resistance can be mediated by the expression of cfr, optrA or poxtA. We developed a multiplex-PCR to simultaneously detect all three genes. The PCR is suitable for microbiological diagnostics in order to restrict further spread of resistances in enterococci.

Keywords: Enterococcus spp.; Linezolid resistance; Multiplex-PCR; cfr; optrA; poxtA.
