Subjects with detectable bacteremia had lower levels of HGF (p = 0.005), IL-15 (p = 0.002), IL-6 (p = 0.05), IP-10 (p = 0.008), MIG (p = 0.03) and MIP-1α (p = 0.03) (Fig 1, S1 Table) compared to subjects without bacteremia. The gene discussed is IL15; the disease is bacterial infectious disease with sepsis.
