Fig. 2From: Distribution patterns of molecular markers of antimalarial drug resistance in Plasmodium falciparum isolates on the Thai-Myanmar border during the periods of 1993–1998 and 2002–2008Distribution patterns of pfcrt and pfmdr1 polymorphisms in P. falciparum isolates collected during period 1 (1993–1998) and period 2 (2002–2008). Significant differences in the prevalence of pfcrt A326S (p = 0.003) and pfmdr1 copy number (p < 0.0001) were found during years of sample collectionBack to article page
