Sequencing profile of nested PCR product of pfcrt genotypes detected in Plasmodium falciparum isolates imported from Africa in Henan province. a The wild type. The haplotype named CVMNK was got from 3D7. b and c The mutation. The haplotype was named CVIET and CVIEK, respectively. d The mixed type. The position was showed by degenerate base. The haplotype was named CVM/I N/E/D/K T/K. The mutation position is indicated by the arrow
