Chronosexuality of Plasmodium species of Central African Muridae.
A host harbouring many parasite species of the same genus is a phenomenon frequently observed in numerous parasitic infections. This is the case for the Plasmodium parasites of Muridae in Central Africa, where three different parasite species are found in the same rodent host species. It is highly likely that these three Plasmodium species are transmitted simultaneously by the same vector. We and others have shown that the maturation periods of the various asexual and sexual stages in the rodent, differ amongst the three parasites. In this article we propose that these differences are the product of complex adaptations which result, for all three Plasmodium species, in a maximum peak of infectivity to the insect vector occurring around 3 a.m., the period of highest activity of the nocturnal host rodent.
