A rapid, 2-well, multiplex real-time polymerase chain reaction assay for the detection of SCCmec types I to V in methicillin-resistant Staphylococcus aureus.
For us to assess the spread of methicillin- resistant Staphylococcus aureus (MRSA), typing of the staphylococcal cassette chromosome mec (SCCmec) is a valuable addition to existing typing methods, such as multilocus sequence typing (MLST). Traditional SCCmec typing assays, that is, that of Oliveira et al. and Ito et al., are polymerase chain reaction (PCR) based, requiring electrophoresis. We introduce a rapid, 2-well, multiplex real-time PCR assay that can be used directly on bacterial suspensions and is able to characterize SCCmec type I to V based on the detection of the ccr genes and the mec complex. The assay was evaluated on 212 clinical MRSA isolates from various countries, associated with MLST clonal complexes (CC) 1, 5, 8, 22, 30, and 45, as well as pig-associated CC398. When comparing the real-time PCR assay with traditional methods, the correct SCCmec element was identified in 209 (99%) of the 212 MRSA isolates. The new assay enables high-throughput analyses for SCCmec on large strain collections.
