In murine typhus, PMN counts correlated well (Spearman’s Rho, p-value) with plasma levels of protein C (Rho = 0.37, p = 0.0089), CRP (Rho = 0.31, p = 0.0026), and the presence of skin rash (Rho = 0.23, p = 0.031), but not with ELA complex levels (p = 0.074). The gene discussed is CRP; the disease is Skin rash.
