Anti-Plasmodium Compositions and Methods of Use

The present invention comprises peptides/antibodies specific for the binding proteins of Plasmodium, a parasite responsible for malaria, hence in effect blocking the parasite’s binding to the erythrocytes. Also included are methods for their use in preventing, diagnosing or treating the related infections.

Although malaria is virtually eradicated in the United States, it continues to be one of the most serious infectious diseases in the world, killing millions of people each year in the countries throughout Africa, Asia and Latin America. In fact, over 41% of the world population lives in the regions affected by malaria. In vitro studies using the antibodies described in the current technology showed ~80% reduction in the number of blood cells infected with Plasmodium parasite. Infectivity studies using peptides demonstrated that they are also specifically able to prevent binding of parasites to blood cells. The claimed antibodies and peptides can also be used for immunization of humans and animals, or for development of diagnostic kits capable of detecting the presence, localization and quantity of the Plasmodium parasites in tissues and cells.
