Changes in the frequencies of Plasmodium falciparum dhps and dhfr drug-resistant mutations in children from Western Kenya from 2005 to 2018: the rise of Pfdhps S436H
Pacheco, M. Andreína; Schneider, Kristan A.; Cheng, Qiuying; Munde, Elly O.; Ndege, Caroline; Onyango, Clinton; Raballah, Evans; Anyona, Samuel B.; Ouma, Collins; Perkins, Douglas J.; Escalante, Ananias A. (Malaria Journal, 2020-10-22)Background Sulfadoxine-pyrimethamine (SP) is the only anti-malarial drug formulation approved for intermittent preventive treatment in pregnancy (IPTp). However, mutations in the Plasmodium falciparum dhfr (Pfdhfr) and ... -

Genetic variation in CSF2 (5q31.1) is associated with longitudinal susceptibility to pediatric malaria, severe malarial anemia, and all-cause mortality in a high-burden malaria and HIV region of Kenya
Kisia, Lily E.; Cheng, Qiuying; Raballah, Evans; Munde, Elly O.; McMahon, Benjamin H.; Hengartner, Nick W.; Ong’echa, John M.; Chelimo, Kiprotich; Lambert, Christophe G.; Ouma, Collins; Kempaiah, Prakasha; Perkins, Douglas J.; Schneider, Kristan A.; Anyona, Samuel B. (Tropical Medicine and Health, 2022-06-25)Plasmodium falciparum infections remain among the leading causes of morbidity and mortality in holoendemic transmission areas. Located within region 5q31.1, the colony-stimulating factor 2 gene (CSF2) encodes granulocyte ... -
Human NCR3 gene variants rs2736191 and rs11575837 alter longitudinal risk for development of pediatric malaria episodes and severe malarial anemia
