For this study, we focused on a smaller number of MRSP isolates for SCCmec characterization and subsequent analysis of PSM-mec production using the following isolate selection process: We chose approximately 50% of the mecA-positive isolates for each ST/Agr group and in a manner in which each group contained at least one isolate from pyoderma, urinary tract, or surgical wound infections (Table 1). This evidence concerns the gene CCL28 and Pyoderma.
