Enterococcus gallinarum carrying both vanA and vanC1 genes were detected from a surveillance culture from a patient staying at the surgical intensive care unit for a few years. E. gallinarum, SI04, was highly resistant to vancomycin (MIC of >or=256ng/mL) and teicoplanin (MIC of >or=256ng/mL). Multiplex PCR for vanA, vanB, vanC1 and vanC2/3 genes revealed SI04 to be positive for both vanA and vanC1 genes. This finding supports the fact that genotyping is needed to classify vancomycin-resistant enterococci (VRE). This is the first report on VanC VRE accompanying vanA gene in Korea.
