Types of nucleotide sequence mutations detected in Plasmodium falciparum isolates imported from Africa in Henan province. The position of mutations was indicated by a rectangle box. N664D was observed in three samples and R471R, A578S, M579I and Q613E were found in two samples. The rest mutations were detected in only one sample. a Four synonymous mutations detected in isolates from Africa; b Two nonsynonymous mutations were associated with ART resistance; c 17 nonsynonymous mutations weren’t associated with ART resistance.; (B = C/G; K = G/T; M = A/C; N = T/A; S = G/A; Y = T/C)
