Background And Objective
The Plasmodium falciparum EBA-175, via Sialic acid dependent glycophorin A, binds to red blood cells and thus plays a critical role in cell invasion. Some part of second allele in its gene encoding in FCR-3 (Section F) and CAMP (Section C) can be found. This study aimed to determine the prevalence of Plasmodium falciparum EBA-175KD alleles in southeastern Iran. Material And Methods
In this cross-sectional study, using polymerase chain reaction Nest (Nested-PCR) with specific primers was used for the two parts of the EBA-175 gene to be proliferated. Ninety–four microscopic positive blood samples from individuals infected by Plasmodium falciparum were obtained from four different locations in southeastern Iran. Results
Of 94 positive samples, 88 were antigen EBA-175KD. Genotype CAMP (714 bp) and FCR-3 (to 795 bp), respectively, in 31 (32.97 %) and 49 (52.12 %) were found. Eight samples have both FCR-3 and CAMP. Conclusion
Both of EBA-175KD dimorphic genes were found. The frequency of FCR-3 allele was higher in the South East of Iran. Thus, this pattern can be considered in making Plasmodium falciparum vaccines for this area.Keywords:
