Abstract

We developed a novel PCR-restriction fragment length polymorphism test for the ccrB gene by using HinfI and BsmI for rapid typing of staphylococcal cassette chromosome mec (SCCmec). When tested with reference strains and methicillin-resistant Staphylococcus aureus isolates, the method proved to be valid and useful for rapid identification of four SCCmec types, especially type IV.
