Fig. 1From: Chloroquine sensitivity: diminished prevalence of chloroquine-resistant gene marker pfcrt-76 13 years after cessation of chloroquine use in Msambweni, KenyaResults obtained after Pfcrt amplicon digestion using ApoI restriction enzyme. Of the 99 samples analysed in the study, 59 % (95 % CI: 0.4824–0.6826) were found to be sensitive to ApoI digestion, thus sensitive to chloroquine, while 41 % were resistant to chloroquine (95 % CI: 0.3221–0.5126)Back to article page
