A set of microsatellite markers to differentiate Plasmodium falciparum progeny of four genetic crosses.

ABSTRACT: BACKGROUND:Four Plasmodium falciparum genetic crosses (HB3×3D7, HB3×Dd2, 7G8×GB4, and 803×GB4) have produced sets of recombinant progeny that are widely used for malaria research, including investigations of anti-malarial drug resistance. It is critical to maintain the progeny free from cross-contamination. Microsatellite polymorphisms can be used to validate parasite identity. RESULTS:A set of 12 markers was developed that differentiates the parents of the four P. falciparum crosses. This typing set identified distinguishing patterns of inheritance (fingerprints) in segregant collections of 15 progeny clones from HB3×3D7, 32 from HB3×Dd2, 33 from 7G8×GB4, and 81 from 803×GB4. Stronger amplification was observed with shorter relative to longer alleles of individual microsatellites. In expe
