There was no association between levels of C1q-fixing antibodies and CRP RBC expression for either P. falciparum– or P. vivax–infected malaria patients (Table 2 and Supplemental Figures 7 and 8) and no association between levels of C1q-fixing antibodies and serum complement activation (as indicated by quantification of complement activation products C3a and C5a) in either P. falciparum or P. vivax malaria (Table 2). The gene discussed is CRP; the disease is malaria.
