Abstract

The New World primate Aotus nancymaae is susceptible to infection by the human malaria parasite Plasmodium vivax and has therefore been recommended by the World Health Organization as a model for malaria vaccine candidate evaluation. We report the isolation, adaptation, titration and genetic characterization of a P. vivax wild strain in splenectomized A. nancymaae monkeys. Parasitemia remained high after 22 passages, reaching 7.88% by Giemsa and Acridine Orange staining and Real-Time PCR determination, making this P. vivax strain a highly infective and reliable asset to be used in P. vivax biological studies and vaccine development. © 2003 Elsevier Science Ltd.
