Plasmodium vivax blood stage antigens, PVESP-1, antibodies and diagnostic assays

摘要

This invention is directed to novel species-specific P. vivax malarial peptide antigens which are proteins or fragments of proteins secreted into the plasma of a susceptible mammalian host after infection, and to monoclonal or polyclonal antibodies directed against those antigens. The peptide antigens, monoclonal antibodies, and/or polyclonal antibodies are utilized in assays used to diagnose malaria, as well as to determine whether Plasmodium vivax is the species responsible for the infection.
