The distribution of MLST types, SCC<i>mec</i> types and virulence genes in different MRSA clones according to <i>spa</i> clone complex.

aCC: clone complex. bAllelic profile in order of arcC-aroE-glpF-gmk-pta-tpi-yqiL. SLV: single locus variant. NT: not typeable, the reasons for the nontypeable of some isolates were mainly due to that a low quality of sequence chromatogram was present for spa typing, or at least one new allele was identified in the seven housekeeping genes for MLST typing, or no corresponding band was found in the multiplex PCR for SCCmec typing. The typing experiments were repeated at least twice for the nontypeable isolates.
