PfHAD1 Protein (IMAGE) Washington University School of Medicine Caption Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery, at Washington University School of Medicine in St. Louis, also is relevant for other infectious diseases including bacterial infections and tuberculosis. The research team defined the crystal structure of the PfHAD1 protein, above. When PfHAD1 is dysfunctional, the malaria parasite is resistant to fosmidomycin, an antibiotic in clinical trials for the treatment of malaria. Credit Niraj H.
