  1. Both lineages' global distribution contradicted Li et al's Old and New World lineages hypothesis; however, the sympatric distribution of lineages was not sufficient to refute the two-lineage hypothesis; rather, understanding their genetic relatedness would seem to be more important. Ninety-six single-clone isolates (48 S type-1 and 48 S type-2) were selected and characterized using a panel of mini-satellite markers to unravel genetic relatedness between P. vivax lineages.
