Falciparum isolates prepared directly from 5 cases of cerebral malaria patients'blood in Mengla County, Yunnan Province and in Yingjiang County, Yunnan Province were used for polymerase chain reaction amplification and the two pairs of oligonucleotides for the highly conserved genes encoding the regions 12—17 in MAD20 merozoite surface protein 1(MSP1) of Papua New Guinea strain of P . falciparum were used as primers. The PCR products were digested with EcoRI and KpnI, respectively, and the generated fragment regions 16—17 were cloned into M13mp18 and M13mp19 vectors and their DNA were analyzed as the templates for DNA sequencing by the dideoxy chain-termination method.

Methods Genomic DNA samples of two isolated Plasmodium falciparum isolate strains prepared directly from 5 cases of cerebral malaria patients′ blood in mengla County, Yunnan Province and in Yingjiang County, Yunnan Province were used for polymerase chain reaction amplification and the two pairs of oligonucleotides for the highly conserved genes encoding FC27 merozoite surface protein 2 (MSP2) of Papua New Guinea strain of Plasmodium falciparum were used as primers. The PCR products were digested with BamH1 and Hind Ⅲ respectively, and the generated fragment MSP2 were cloned into M13mp18 and M13mp19 vectors and their DNA was analyzed as the templates for DNA sequencing by the dideoxy chain-termination method.
