The multiplex PCR assay described here provides a simple, reliable method for classifying types and major subtypes of SCCmec I-V in Staphylococci, with simultaneous discrimination of MRSA from MSSA. The assay is robust, conveniently done in a single PCR reaction and results are easy to interpret. The assay does have limitations in that it targets individual loci within each SCCmec type, but does not offer comprehensive ccr and mec complex typing, and therefore cannot be considered a go...

multiplex pcr assay for typing of staphylococcal cassette chromosome mec types i to v in methicillin-resistant staphylococcus aureus

Stafilokok Kaset Kromozom mec (SCC mec) yazarak

This updated M-PCR is able to determine (classify) SCCmec types I-V, as well major subtypes of SCCmec IV. The assay targets unique and specific loci of SCCmec I, II, III, IVa, IVb, IVc, IVd, IVE and V, with concomitant mecA gene detection. Tentative identification of SCCmec VI and VIII is also possible, but would require further testing to confirm. Figure 3 illustrates representative SCCmec I-VI and VIII and the locations of each target within the ele...
