Summary Intrahepatocytic transformation in vivo of the rodent malaria sporozoite of Plasmodium berghei, into the young trophic exoerythrocytic tissue stage was studied by immunofluorescence, light- and electron microscopy. The first 20 h of intracellular life were involved entirely in dedifferentiation with limited proliferation of organelles. From about 20 h onwards nuclear division commenced, rough endoplasmic reticulum became markedly expanded, and mitochondria increased in numbers. However, remains of the sporozoite pellicle (i.e., inner membranes and subpellicular microtubules) persisted for at least 28 h, which correlates with the persisting reaction of young exoerythrocytic forms with antisporozoite antibodies. In general, the basic mechanism of transformation resembles that of the ookinete into oocyst and that of the merozoite into erythrocytic trophozoite.
