Evidence for intragenic recombination in Plasmodium falciparum: identification of a novel allele family in block 2 of merozoite surface protein-1: Asembo Bay Area Cohort Project XIV.

We have investigated intragenic recombination in Block 2 of the merozoite surface protein-1 (MSP-1), where three allele-specific families: K1, Mad20, and RO33 were previously known. Using parasites from western Kenya, we have found a fourth Block 2 allele type, which is a recombinant between Mad20 and RO33 alleles. These recombinant alleles, which we have… CONTINUE READING
