G.; Perkins, Douglas J.; Mukundan, Harshini; McMahon, Benjamin H.; Doggett, Norman A. (PLOS ONE, 2021-01-01)

Non-typhoidal Salmonella (NTS) is a major global health concern that often causes bloodstream infections in areas of the world affected by malnutrition and comorbidities such as HIV and malaria. Developing a strategy to ...

Direct detection of bacteremia by exploiting host-pathogen interactions of lipoteichoic acid and lipopolysaccharide

Kubicek-Sutherland, Jessica Z.; Vu, Dung M.; Aneesa, Noormohamed; Mendez, Heather M.; Stromberg, Loreen R.; Pedersen, Christine A.; Hengartner, Astrid C.; Klosterman, Katja E.; Haley, A. Bridgewater; Otieno, Vincent; Cheng, Qiuying; Anyona, Samuel B.; Ouma, Collins; Raballah, Evans; Perkins, Douglas J.; McMahon, Benjamin H.; Mukundan, Harshini (Scientific Reports, 2019-04-17)

Bacteremia is a leading cause of death in sub-Saharan Africa where childhood mortality rates are the highest in the world. The early diagnosis of bacteremia and initiation of treatment saves lives, especially in high-disease ...

Integrated OMICS platforms identify LAIR1 genetic variants as novel predictors of cross-sectional and longitudinal susceptibility to severe malaria and all-cause mortality in Kenyan children

Achieng, Angela O.; Hengartner, Nicolas W.; Raballah, Evans; Cheng, Qiuying; Anyona, Samuel B.; Lauve, Nick; Guyah, Bernard; Foo-Hurwitz, Ivy; Ong'echa, John M.; McMahon, Benjamin H.; Ouma, Collins; Lambert, Christophe G.; Perkinsa, Douglas J. (EBioMedicine, 2019-07-02)

Background Severe malarial anaemia (SMA) is a leading cause of childhood mortality in holoendemic Plasmodium falciparum regions. Methods To gain an improved understanding of SMA pathogenesis, whole genome and transcriptome ...

Nonsynonymous amino acid changes in the α-chain of complement component 5 influence longitudinal susceptibility to Plasmodium falciparum infections and severe malarial anemia in kenyan children

Raballah, Evans; Wilding, Kristen; Anyona, Samuel B.; Munde, Elly O.; Hurwitz, Ivy; Onyango, Clinton O.; Ayieko, Cyrus; Lambert, Christophe G.; Schneider, Kristan A.; Seidenberg, Philip D.; Ouma, Collins; McMahon, Benjamin H.; Cheng, Qiuying; Perkins, Douglas J. (Frontier in genetics, 2022-08-14)

Background: Severe malarial anemia (SMA; Hb < 5.0 g/dl) is a leading cause of childhood morbidity and mortality in holoendemic Plasmodium falciparum transmission regions such as western Kenya. Methods: We investigated ...

Ingestion of hemozoin by peripheral blood mononuclear cells alters temporal gene expression of ubiquitination processes

Anyona, Samuel B.; Cheng, Qiuying; Raballah, Evans; Hurwitz, Ivy; Lambert, Christophe G.; McMahon, Benjamin H.; Ouma, Collins; Perkins, Douglas J. (Biochemistry and Biophysics Reports, 2022-01-11)

Plasmodium falciparum (Pf) malaria is among the leading causes of childhood morbidity and mortality worldwide. During a natural infection, ingestion of the malarial parasite product, hemozoin (PfHz), by circulating phagocytic ...

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 ...
