It has been proposed that changes in the pH of the digestive vacuole might underlie the decreased accumulation of chloroquine by chloroquine-resistant. Our view is that use of this term applies most precisely to the P. falciparum phenotype distinguished by 2 features of parasites cultivated in vitro 1 the confirmed ability to survive at 100 nM or 33 ng/mL of chloroquine base in standard conditions of continuous culture and 2 chemosensitization of the chloroquine response by 1.0 μM.
