Analysis of the C-terminal nucleotide diversity of imported PfCSP in Henan Province. The nucleotide sequences of the C-terminal nonrepeat region (amino acid sites 311 ~ 363 fragments) of imported PfCSP in Henan Province were selected. The nucleotide diversity (π) was calculated by DnaSP software with a sliding window length of 10 bp and a step size of 5 bp
