NIAID media availability: Examining genetic variability of malaria parasite offers insight
...hers understand the parasite's evolution and study malarial
drug resistance. Two companion studies being published simultaneously include one led by NIAID scientists that identifies new antigens--pieces of the pathogen that are recognized by the immune system. Some of these new antigens may be potential targe...
