Phenotypic and cytotoxicity assays between the ST59-t437 and ST239-t030 strains in this study. *Statistically significant difference (p value < 0.05), and “ns” indicated no statistical significance. A. The growth curve of three MRSA strains; B. The staphyloxanthin results of three MRSA strains; C. Whole blood survival test of three MRSA strains; D. H₂O₂ killing examination of three MRSA strains; E. The light microscopy results of three MRSA-infected Hep2 cells (200×). The lab numbers in the figure indicated that the cells were infected with each strain; F. Cytotoxicity results of three MRSA strains infected with Hep2 cells
