Figure: anti-α-Gal antibody responses in Plasmodium vivax-infected (Pv-infected) patients. Levels of IgG (A) and IgM (B) against α-Gal were evaluated in plasma from healthy individuals (n = 20) and patients with vivax malaria (n = 112) by enzyme linked immunosorbent assay (ELISA) and were expressed as values of optical density (OD). Results are shown as median values and interquartile ranges. Anti-α-Gal antibodies levels were compared between non-exposed and Pv-infected patients using Mann-Whitney U test and asterisks indicate statistically significant difference (p-value < 0.05).
