Towards an in vitro model of Plasmodium hypnozoites suitable for drug discovery. Failure to detect hypnozoites in hepatic tissue containing exoerythrocytic schizonts of Plasmodium knowlesi.

P. malariae and susceptible P. falciparum infections are eliminated by treatment with chloroquine alone. • When there is little or no likelihood of immediate reinfection, elimination of naturally acquired P. vivax and P. ovale infections requires subsequent administration of primaquine to eliminate persistent intrahepatic forms hypnozoites.
