SCIN and bacterial infectious disease with sepsis: The antigens associated with the most significant elevations in IgG levels in bacteremia patients compared to controls were SA0688 (Figure 4) and glucosaminidase (P<0.0001), the immune modulators SSL5 (P<0.0001), SSL1 (P  = 0.0007) and SCIN (P  = 0.0004), and the toxins gamma-hemolysin B (P  = 0.0007) and leukocidin F (P<0.0001).
