RESEARCH PROJECT TOPIC ON INACTIVATION OF MALARIA PARASITES IN BLOOD

ABSTRACT

Malaria parasites are frequently transmitted by unscreened blood transfusions in Africa. Pathogen reduction methods in whole blood would thus greatly improve blood safety. We aimed to determine the efficacy of riboflavin plus irradiation for treatment of whole blood infected with Plasmodium falciparum.
Riboflavin plus irradiation treatment of whole blood damages parasite genomes and drastically reduces P. falciparum viability in vitro. In the absence of suitable malaria screening assays, parasite inactivation should be investigated for prevention of transfusion-transmitted malaria in highly endemic areas.
Malaria causes hundreds of thousands of human deaths every year, and the World Health Assembly has made it a priority. To help eliminate this disease, there is a pressing need for the development and implementation of new strategies to improve the prevention and treatment, due in part to antimalarial drug resistances. This chapter focuses on two strategies to inactivate the malaria parasite in blood, which are photodynamic therapy (PDT) and inhibition of hemozoin formation. The PDT strategy permits either a control of the proliferation of mosquito larvae to develop some photolarvicides for the prevention or a photoinactivation of the malaria parasite in red blood cells (RBCs) to minimize infection transmission by transfusion. The inhibition of hemozoin formation strategy is used for the development of new antimalarial drug by understanding its formation mechanism. Malaria in humans is an infectious disease caused by parasites of the genus Plasmodium, and it is spread to humans by the bite of the female anopheles mosquito. Among the species of Plasmodium, five are capable of inducing human disease. These are the species: falciparum, vivax, malariae, ovale, and knowlesi. The first is the most widespread and the most virulent, which is responsible of 80% of infections and about 90% of deaths, especially in Africa
