Figure 2From: Polymorphism of Plasmodium falciparum Na+/H+ exchanger is indicative of a low in vitro quinine susceptibility in isolates from Viet NamAssociation between QN IC 50 (nM) of parasite isolates and the number of (A) DNNND repeats or (B) NHNDNHNNDDD repeats in Pfnhe-1. (A) Median QN IC50 of isolates with 2 or more DNNND repeats are significantly higher than isolates with less than 2 DNNND (p = 0.015) (B) Median QN IC50 of isolates with 1 NHNDNHNNDDD repeat are significantly higher than isolates harbouring 2 repeats (p < 0.01).Back to article page
