Phylogenetic relationship of Plasmodium vivax circumsporozoite 3′ terminal region. The vk210a from Mexico and those from Nicaragua cluster together with other Latin American (LA) isolates in one branch of the tree. However csp sequences vk210 (b and c) cluster with sequences from Korean parasites. As well, the vk210d sequence clustered with parasites from other regions outside LA. All constructions were inferred using the Neighbour-Joining method. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) are presented next to the branches. Csp sequence analysed in here are in blue.
