Especially, the median levels of CRP (68.89 mg/L) and SAA (280.75 mg/L) in the bacterial infection group were significantly higher than those of CRP (20.26 mg/L) and SAA (81.16 mg/L) in the viral infection group and the healthy control group (CRP = 1.67 mg/L; SAA = 2.96 mg/L; p < 0.05). This evidence concerns the gene CRP and bacterial infectious disease.
