Cytokines and chemokines associated with immune cell development, virus infection, and aging, including IP-10, eotaxin, and IL-3, showed no difference among these strains (p = 0.343–0.918 and p = 0.089–1.000 for USA300-C2406 compared with M92 and USA400-CMRSA7). The gene discussed is IL3; the disease is viral infectious disease.
