Abstract
Malaria is a potentially mortal disease caused by parasites of the genus Plasmodium spp. It has a wide distribution in the world and unfortunately there are several factors that make its control difficult; among which the development of pharmacological resistance to the different drugs used to treat this disease stands out, which makes it necessary to design new compounds that have an antimalarial effect. Previous studies have shown that vanadium has a broad antiparasitic spectrum and is also safe for the host, so the objective of this research was to evaluate the antimalarial potential of sodium metavanadate (SM) and to analyze the ultrastructural changes in parasites exposed. The method consisted of inoculating CD-1 male mice with Plasmodium yoelii yoelii and administering a 10 mg/kg/day dose of SM orally for 4 days. On the fifth day, whole blood samples were obtained, processed for ultrastructural analysis, and the changes in the different parasite stages were compared against the control. Our results showed that SM decreased parasitemia compared to the group that did not receive treatment and modified the ultrastructure in all parasitic stages because it damaged the membranes, causing alterations mainly in the nucleus and in the mitochondria as well as the loss of cellular organization, which could affect the integrity of these parasites and decrease its viability.

Abstract
BACKGROUND Malaria is a parasitic disease with the highest morbidity and mortality worldwide. Unfortunately, during the last decades, the causal agent, Plasmodium spp., has developed resistance to chloroquine and artemisinin. For this reason, metallic compounds have been proposed as an optional treatment since they have shown a potential antimalarial effect with diverse action mechanisms in the parasite and the host. OBJECTIVE To show the possible targets of metallic compounds in Plasmodium spp. CONCLUSION The metallic compounds are an option attractive to treatment for the malaria, for its low cost and its great activity to reduce parasitemia; however is necessary more studies principally in vivo in order to know the interactions that it can have in an experimental model.
