Relapses in malaria are caused by hypnozoites, the latent hepatic stage formed by species such as Plasmodium vivax and Plasmodium ovale. Drug discovery programs have been severely hampered by a lack of in vitro cultivation methods for malarial hypnozoites. Only one drug, primaquine, is currently available, but its use is limited in people with glucose-6-phosphate dehydrogenase deficiency. Here, Laurent Dembélé and colleagues offer a system that can be used to monitor the growth and development of Plasmodium cynomologi liver-stage forms, a model for P. vivax, for up to 40 d.
