Considering transfer and genetic dynamics of the parasite population in a specific area can help us to predict the spread of the infection either emergence of new cases or drug resistance in the context of elimination program in the malarious areas. Study on the genetic diversity of common alleles in a given geographical area, for vaccine and immune level studies can be important. The purpose of this study was to know the status of P. vivax Duffy Binding Protein (PvDBP) polymorphism in patients infected with the parasite in malaria endemic southeastern Iran. The fragment of gene corresponding to PvDBP of thirty P. vivax malaria infected individuals was amplified. A 1176 bp band related to this fragment was purified and PCR--RFLP method was employed using enzymatic digestion with PstI and RsaI restriction enzymes. Ten percent of samples were sent for sequencing. PCR--RFLP showed that 99.7% of the samples were cut as the same together, either the PstI enzyme or the enzyme of RsaI. In each case, only 2 isolates were unlike others. Findings revealed that there is at least 96% identity among isolates in the nucleotide level. Amino acid pattern of PvDBP in Iranian isolates showed little discrepancies with those PvDBP genes that have been recorded in GenBank. Sequencing of PvDBP isolates of Iranian P. vivax infected patients showed low level of genetic polymorphism among them. Results of this study can prepare valuable information for malaria policy makers to intend them in their malaria control program.
